I can’t think of anything more satisfying then seeing one of my HDRs Printed large and hung on my wall. Well, maybe hung on someone else’s wall I like better. But either way, seeing that large print just completes things for me.
So I would encourage YOU to print your images and I’ll give you some tips to get great prints because many people don’t print anymore or haven’t printed since they got their digital cameras so they aren’t always familiar with the process.
This will be about printing at a commercial lab not home printing. Home printing on Large format Inkjet printers is and art and science all to itself and most people can’t afford to spend what it takes to do it right, so for their large format prints (larger than 8 x 10) most people turn to commercial labs.
Now if you want, you can off course go to the local drug store or big box stores like Wal-Mart and Costco. Most are now offering larger size prints and even things like stretched Canvas Gallery wraps but I would encourage you to use some of the consumer arms of professional labs or, well, if you are a professional, those professional labs.
The prints are of a much higher quality on quality papers and done by technicians that know what they are doing to assure the best possible prints.
I use Bay Photo labs but I have a professional account with them. However anyone can get their services if you use SmugMug Besides access to great Bay Prints, SmugMug is a fantastic photo sharing site and community serving both amateur or professional photographers
One of the other labs you may want to try is MPIX.com, they are the consumer arm of Miller’s professional labs. and offer a wide variety of Print products.
All online labs allow you to upload your images, choose your sizes of prints, pay for and then have your prints shipped directly to your door. Some even offer it the next day so while it may not be as quick as your 1-Hour lab (why do they always ask when I want my prints back? Ummm…in an …hour?) It is plenty quick and convenient.
There are generally two types of prints from Digital Files
- True Photographic prints also known as Digital – C Prints, Light jet or Lambda Prints. These prints are made on true light sensitive Photo papers that are excited by a laser and finished in a traditional photographic process
- Giclėe (pronounced zhee- clay) are Fine art Ink Jet Prints printed on a variety of papers from Photographic style; Glossy, semi, Gloss, matte. To fine art type papers
Either style can give you a very high quality print but they just have different looks and qualities. Digital-C prints tend to have a higher dynamic range and deeper blacks, but it can depend highly on what your images look like and how you want them to appear. The best thing to do is to get some sample prints made in different styles to determine what you like best.
Preparing your Image Files – Resolution
Probably the most confusing thing that people fid about printing and photo files themselves is; resolution. PPI, DPI, 8 x 10, 4800 x 3600, 250ppi, 300ppi, 360ppi etc etc etc…Yikes.
OK, so let’s make some sense of this all.
Your digital photo files have a pixel x pixel resolution. In the case of My Canon 5D, my images come off the camera at 2880 x 4320. This is the most important number you need to know. Forget just about everything else you may have heard or known. These are the numbers that matter when it comes to Resolution and printing.
The other number you will hear a lot about is PPI, or Pixels Per Inch. This number ends up being the source of more confusion than any other. But I will try to show you how to best use this number
From these numbers we can determine how big of a print we can make. All Print labs have a Recommended PPI Resolution and also a Minimum PPI Resolution. In most cases, labs recommend 250PPI for Digital- C prints and 300PPI for Giclėe prints. Most labs have a minimum resolution requirement of 100PPI
How do I determine my PPI for the print I want to have made?
Forget about what your image may say: “I have a 3000 x 2000 @ 300 PPI image or I have a 3000 x 2000 @ 72 ppi” PPI in that context does not matter one bit. Both of those digital files are identical in size.
So, the first thing you need to know is; Your Pixel by Pixel resolution and then the size print you want to have made. We’ll use my 5D image for example
File size 2880 x 4320 and I want to have a 12” x 18”, I simple divide the file size by the print size
2880 / 12” = 240ppi
4320 / 18” = 240ppi
So I know from the PPI number I got, that is close to the ideal ppi my print lab (250ppi) needs to make an excellent quality print. Don’t try to be perfect, close is good.
What if I want to make a larger print, say 20” x 30” I simply do the math again.
2880/ 20 = 144ppi
4320 /30 = 144ppi
My ppi is now 144. It’s less than the perfect number but still well within the minimum requirements my lab needs to print me a great print.
Now I really want to go big. I want to make a Wall Size 40” x 60” Print. Let’s do the math one more time
2880/ 40 = 70ppi
4320/ 60 = 70ppi
My ppi is 70. NOW I have a problem. This print size is below the minimum ppi resolution my lab requires and it will make for a poor quality print. (I will give a possible solution at the end of this post)
Now that you know you have a large enough file for the size print you want to have made. Let’s make sure that the file is in best shape to be uploaded and printed
Color profiles or ICC profiles are the bits of information in your images that tell others or other devices, this color is this color. The major ones we use are sRGB, Adobe RGB, and Pro Photo RGB. If you don’t know which one you use you are probably using sRGB but you can check your file’s EXIF data to tell you what your file is.
Most labs either have a color profile they want the files in or at the very least, ask that you embed the profile in the image so they know what to do with that file. For instance MPIX requires that your file be sRGB. While Bay will accept either sRGB or Adobe RGB as long as you embed the profile into your image. Check with your lab
Lightroom while it works for the most part in Pro Photo RGB, when you select an image for Export you can tell Lightroom what profile you want to use and Lightroom will convert the profile upon export (check your export settings)
Photoshop has a working profile that you set. But even if you are say working in Adobe RGB, before you save a print copy, you can Convert the profile to any you want by going to Edit> Convert to Profile and then save your image with that profile embedded.
Speaking of saving your file, almost every lab will accept JPEG files; some will also accept Tiff or other file types. Check first to make sure before you upload. Even though my portfolio files are all saved as either Tiff or PSD files, when I make a print copy, I save them as JPEGs for universal use at any of the labs I use. JPEGs even though they get a bad rap sometimes are fine for your print file. Save your JPEGs at the highest quality your software provides.
Nothing get new photographers mad than trying to understand cropping. They go to order an 11” x 14” print and can’t understand why parts of their image are cut off.
Aspect ratios: Most DSLRs have as aspect ration of 2:3 this translates in to print sizes of 4” x 6” and multiples there off.
But the problem is a lot of the common print sizes are based on either popular Frame size or print size of days gone by (that film stuff) So we have print sizes of 5” x 7”, 8” x 10” 11” x 14” or 16” x 20”. None of those sizes match up to our 2:3 aspect ratio of our Digital Images so part of our photos MUST be cut off to fit those sizes. So if you want to print in those sizes, you must keep this in consideration when shooting and shoot larger to allow that part will be cut off when you print.
The good news is, the frame industry and the print labs have known the photographers frustration with this so they have begun offering both prints and frames and/or mats, to work with the standard aspect ratios of DSLR camera.
Other sizes that require no cropping are:
6” x 9”
8” x 12”
12” x 18”
16” x 24”
20” x 30”
24” x 36”
Soft-proofing ( Advanced – Photoshop Full Version only)
This section is for more advanced user and those that use Photoshop (the full version) If you’re not skip over it, you’ll be fine.
We want our prints to look like what we see on our screen but the truth is Prints are different than what our image looks like on screen. Prints are front illuminated; Our LCD screens are back-lit. Also every print machine is different, every paper is different, they have a different look to them. They respond to different colors differently.
So how can we know ahead of time what our prints will look like? By soft-proofing.
Soft-Proofing is a simulation of what the combination of Machines and papers will look like. A Lot of print labs have ICC Profiles that you can download that you can use with Photoshop to do that simulation. Once you download the profile from the lab and install that profile to the correct location on your computer. In Photoshop you go to View> Proof Set-up and Custom. From there you will drop down a list of profiles till you find the one you want. Then by Ctrl +Y or (Cmd+Y mac) , you can toggle between your image ad the print simulation to see if you need to make any changes to the file to make it as good as you can get printed.
For more in-depth information on soft-proofing simply Google it. There are some good explanations to be found.
I cannot stress this enough how great it is to see your work in print. Even in my own home I have many 20 x 30 Standout Prints, 16 x 24 Matted and Framed Prints, 36 x 36 Stretched Canvas Gallery warps and even a 48” x 48” Photo Mural printed directly on Aluminum Metal (LOVE these). So give it a try.
One last thing to consider once you get your prints on the wall is how they are illuminated. Proper lighting on a photograph can make all the difference in the world. Whether that is halogen spots or Track-lights or just Portrait Lights Hung over a Framed Print. Putting good light on that print will be the difference between blah and wow.
OK, I know that was a lot to read on something that seems as simple as getting a print but I appreciate you making it all the way thorough.
Addendum: I said earlier I would talk about what to do if you want a bigger print than your file was capable of. One of the things you can try is resizing the image. Unfortunaly resing a image with too few pixels intoi a really large print usually is not that sucessful. If however you have a very good quality image that is sharp and low noise you can use a bit of software that has gotten me out of trouble many times. OnOne’s Perfect Resize (formally Genuine Fractals. This software uses a very powerful resizin algorythm that is much different than what we can do in our normal editing software. The good thing is we can try it and then see for ourselves how the image looks at that size and see if it has too many resizing artifacts tpmprint well. In most cases with a good file you can get at Least the next biggest size print than what you were capable before and sometimes much more than that.

Here are a couple of great HDRs from reader Duanne K Willis
The first one is an HDR Panoramic.
Layers of a Sunset (click image to enlarge)
THI: Where was this image shot?
DW: Table Rock Lake
THI: What Camera and Lens did you use?
DW:Nikon D7000 Nikon 18-105 shot at 50mm
DW: 4 shots -4, -2, 0, +2 ( 1/2500, 1/640, 1/160, 1/40)
THI: What Processing did you do?
DW: Photomatix; Lightroom and photoshop elements.Normal workflow for Levels adjustments and then Crop for Pano
THI: Thoughts behind this image?
DW: This was a image I had been thinking about for a while and had attempted it about 6 times over a 1 year time frame, but the conditions were just not right. Usually I had boats in the water, clouds or a heavy haze. Finally this summer we had a string of clear days and nights. This was taken about 15 minutes before the sun went down below the horizon. It was a perfectly clear night. I waited just until the sun did not have that bright white spot. The conditions allowed me to capture the nice vertical layers of the Sunset along with the layers of the hills.
Also from Duane is this HDR Image
WaterPainting (Click image to enlarge)
THI: Where was this image shot?
DW: Alley Mill Springs
THI: What Camera and Lens did you use?
DW:Nikon D7000 Nikon 18-105 shot at 32mm
DW: 3 images -2, 0 , +2 (1/2 sec, 1/8 sec, 2 Sec)
THI: What Processing did you do?
DW: Photomatix; Lightroom and photoshop elements.I used my normal workflow for Levels adjustment. I sometimes will get very saturated Greens and with this image I had just read the Post by Peter talking about using a Black and White layer to help tone down his colors in a night shot. I have been doing this a lot with my images and it really helps
THI: Thoughts behind this image?
DW: This was taken at about 6:30 am. I had really been wanting to add to my portfolio some water shots and was walking along the trail that goes behind the mill. I saw this opening with these great Moss rocks and the light just starting to highlight them on the top. When I shoot water I really want it to look like a paint brush made the strokes. I think sometimes the really silky water, just takes away from the scene. I knew I had no filter on my lens, but that morning there was a nice fog and the Sun had not poped up over the Cliff side, so I new I would get a nice shutter speed. As soon as I looked at the image in my screen I could see the nice brush strokes of the water. That just made the 2 1/2 hour trip worth the drive.
I really like both of these images and what I like is, Duane had an idea in his head and then used his knowledge to achieve that and they both work exactly as he had planned. I like the processing he did, it is of course to my style of doing things. But don’t think I don’t like other styles, Just do them well.
Thanks Dunne for sending in thses images.
Remember I’ll be more than happy to post images or critique reader images.
Please send Duanne some love or suggestion in comments. We all like to know what people think, good or bad because it helps us to get better.
I have a line of Christmas Cards called The Lone Ornament. So when it snows inSouthern California…yes, it snows here…provided you go above 7,000 feet – I head up to the mountains to shoot for the next year’s card. So after it rain here on Thursday I knew there would be snow up there on Saturday.
So I headed up to the mountain hamlet of Idyllwild. It started to snow as I arrived and when I got to Humber State park it was a “Picture” perfect scene. About 6 inches of white puffy freshly fallen snow and it was snowing lightly as the sun played in and out of the clouds. I could not have asked for a better day…and I LOVE snow.
I got the shots I needed for my cards and they came out fantastic (no you can’t see them, they are a secret till December of 2012). When I was done I thought I would hike up the trail and try having some fun shooting in the woods and do some HDR after all, surely snow have a high dynamic range…or… we would think.
Measuring the DynamicRange
I hiked up the trail (Huffing and puffing, 7,000 feet is rough) and set up my tripod amongst some beautiful scenes and I set about to measure the dynamic range. I set my meter to spot metering. In snow spot metering is essential for measuring the dynamic range, using other modes the snow played too big a part in the metering and threw off any real measurement. Using Evaluative/matrix metering actually showed NO dynamic range as it metered everything the same.
At the time the sun was out and at f/16 and ISO 160, for the brightest spot on the snow I got a shutter speed of 1/500, for the deepest shadow area of tree bark I got a shutter speed of 1/20. OK that sounds good, so roughly 5 stops of range to cover.
But wait a minute. We have to remember one of the most important facts about in camera metering. In camera meters are reflective meters; they measure the reflected light off our subjects. And they are calibrated for middle gray. They will get the exposure correct if the object you are metering is middle gray (18%) or a midtone. If we measure white or black, the meter tries to make them gray. It will do that by underexposing white and overexposing black, both by about 2 stops.
So knowing that, that 1/500th shutter speed would underexposure our snow by about two stops. So really the exposure for the snow would be 1/125th. So now 1/125th to 1/25 is really closer to 3 stops difference in range, which tells us we really don’t need HDR!
But I pressed on and did some anyway.
What I found worked best was 3 exposures. And if I was using auto Exposure Bracketing it was best to also add in +1 Exposure Compensation to make up for the meter misreading the snow. Even though we know that snow will make the meter under expose by 2 stops, using +2 Exposure compensation was too much and our final bracket image was just too blown out. If I shot manual, I took the same compensation in mind and started my bracketing at 1/125 or 1/200
The other thing I found was spacing, if the sun was shining bright on the snow, + – 2 stops worked fine. If the sun was not shining brightly on the snow + – 1EV actually worked better. Yes that is NOT a broad range but again, this is not as dynamic a situation as we may think it is.
Here are three images I shot
Processing for snow
Shooting snow in HDR is just half the battle, processing it correctly is the send part. The problem most HDR processing programs have is handling white and especially large amounts of white. This has been my one pet peeve will all the developers. But it’s actually to be expected. Just like our meters want to make everything gray, that is also the function of the tone mapping of HDR programs. They will try to make everything a mid tone. This results in graying of all things white. So we need to take some steps to assure that doesn’t happen.
Regardless if you are using Photomatix Pro or Nik HDR Efex Pro or any HDR program what we have to watch is how much compression we apply. In Photomatix this is Strength and Lighting adjustments. In HDR Efex Pro it is Tone Compression.
If we were processing in Photomatix we would want our Lighting adjustments to be Natural + and a strength of under 50. In Nik HDR Efex Pro, which I used here, I used Tone Compression. set to 0.
That still leaves us with some pretty dingy whites so we need to make an adjustment to our white levels and quite a bit of it to, I used between 20 and 40% more white levels to get the images right, you want the brightest parts of the snow just below blowing out. I also added about 12% blacks to bring back a little shadow detail and then about 20% to the structure. My fine adjustment just to bring out a bit more detail I upped the method strength to 20% with the Neutral method.
This gave me the most pleasing look to the image, the cool part was I needed no further post processing for any of the images in Photoshop or Lightroom.
Now comparing it to a single image shot with the correct exposure, you really won’t see a huge difference. In fact I think you could work with a single image and get similar results. We don’t really see a big difference in range because quite frankly, there isn’t much anyway. But there is an improvement in detail that I feel may be worth it. Would I shoot snow in HDR again? Maybe, but I am not sure it was worth the effort completely.
Perhaps since it was such a beautiful day in the wood and snow, I should have forsaken the tripod and all the set-up and time it took and just enjoyed the hike more and shot conventionally…but then again…I DO run The HDR Image…soooo
Hope that helps,
Final note to self, make sure you waterproof hiking boots, subset note to self, be thankful that wool socks keep you warm even when wet.
I’ve often talked about only shooting HDR when necessary and then have gone on to tell ways of measuring the Dynamic Range to see if it is sufficient to warrant shooting HDR.
But here is a quick way to determine if you do need HDR, It’s not fool proof but usually is a very good and quick way to at least know you may be on the right track.
I was coming back from hiking in the snow in the mountains and I saw this driving home thinking it might be an interesting shot. So I snapped one off. One quick look and I knew it would never be OK without HDR. I was just too tired from hiking to break out everything to set up so I just passed it by. But I noticed the histogram and really made the connection between the two
Here’s the image and the Histogram. Whenever you see two big peaks at each end and a really shallow valley in between, you may need HDR
Hope that helps,

For how to submit your image for feature or critique see THIS POST
So, I am the author of a blog on HDR so my images should be the best possible example of how to do HDR and be great images and I thought I was doing a fairly good job of that. But then for research on what people might be interested in learning I went on to a lot of forums to see what people were talking about and how they were doing things.
I knew my methods and I thought they worked. But people were talking so differently and in large numbers of people were doing it differently than I. Heck even when I visited a major HDR software company, THEY were doing it differently.
Everyone was talking about 7 and 9 images shot. 1EV or smaller increments. making adjustments on the raw images before processing into an HDR ( I will only do White balance adjustments pre conversion). All kinds of thins to get the perfect image. And I thought to myself, my old adage that in most cases to shoot just 3 frames 2EV apart, surely must be wrong. I must just be lazy and I wasn’t putting enough effort into getting the best image possible.
So lately I was shooting 7 frames, 9 frames 10 frames! Standing on my head, wearing copper bracelets, eating vegan…anything to get that ultimate HDR Image…and they weren’t
It smacked me in the face the other evening after I shot the Hotel Del Coronado, I wasn’t even excited about shooting it because. I had to get it perfect because it was for a tutorial so the pressure was on and surely I needed to shoot 20 frames and lock my mirror up and…ugh. When I got home and processed the images. I first did the 6 frames 1EV spacing I had shot, then I went back and just did 3 frames 2EV apart. There was NO difference in fact the 3 frames were slightly better on white areas and only then when zooming into 100%. Visibly there was no difference and shooting more than 3 frames with closer spacing was in fact just a huge waste of time.
Whih is which?
It was at that point I thought back to my most successful HDR images almost all of them were shot with just 3 exposures . The reason the software company wanted to talk to me was because I was getting results they weren’t (Lots of exposures) This image, my most successful selling image…3 exposures.
My magazine cover… 3 exposures
We need to remember that when we take an exposure it doesn’t just span that 1EV or 2EV spacing,most of the exposures are easily covering a dynamic range of 6 – 7 stops. As we move to the extreme ends of exposure our dynamic range will decrease because we fall into the noise floor or blowout region. But we still have a wide enough dynamic range in each shot that 2EV spacing is enough. Are there times that we need to do more than 3 exposures? Of course there is and we saw in the Shooting the Sun or Shooting Architectural Interiors post, you may need to shoot beyond 3 because there is just that much Dynamic range that needs to be covered. But still 2EV pacing is fine, cover the range you have measured and stop. The worst sin of all is overshooting the range. Totally Blown out or most black exposures do nothing and in fact detract and take away detail from the image.
So I will go back to my original statement. In most situations 3 Exposures 2 stops apart is sufficient and beneficial and will save you time in shooting and especially in processing time. You don’t need that agony of 10 exposures waiting for them to merge.
And my last bit of advice is; If the scene does not call for HDR, don’t use HDR. I think I was reminded of that when I was shooting the sun for that series. Later in the day in a pasture during the golden hour when the sun was low and soft and the dynamic ranges decrease and are able to be captured. I shot this image which turns out to be one of my favorite images of this year. Single exposure – no HDR. Is it a big and bold image like a lot of HDRs? Absolutely not. It’s a simple scene of a simple subject but with the essence of great photography…amazing and beautiful light
This all of course is just my opinion and I expect you to experiment and try and do what you find best. But this is my opinon for the day…and longer
Hope that helps,
Unified Color annouced two new releases to their HDR Software.
I’ve been interested in giving it a whirl but just haven’t had a chance yet so maybe with a couple of brand new releases it may be a good time to give them a try and then write a full review of the products. Heck all of us are always looking for new software that may do it better or quicker or both.
Here is their press release just to give you an idea of what’s new for them.
Check back here for a review shorttly.
UNIFIED COLOR ANNOUNCES HDR EXPOSE™ 2 AND 32 FLOAT® V2
Major upgrades to both products include more than 26 new and improved features, faster processing speed and streamlined user interface
SOUTH SAN FRANCISCO, CA – DECEMBER 13, 2011 – Unified Color Technologies, the high dynamic range imaging experts, today announced the latest upgrade to its popular HDR image editing software offerings, HDR Expose 2, the standalone HDR software that empowers photographers to create the most true-to-life HDR images possible, and 32 Float v2 an 32-bit HDR image editing plug-in for Adobe® Photoshop®..
Built upon Unified Color’s Beyond RGBTM color technology platform, both HDR Expose 2 and 32 Float v2 separate an image’s color component from its luminosity component, enabling photographers to adjust each independently; thereby preventing the tell-tale color shifts often associated with HDR photography and producing much more natural-looking tone mapped results. HDR Expose 2 and 32 Float v2 are also true 32-bit color editing tools that take full advantage of all the available shades of color and tone in a 32-bit HDR image for the smoothest, halo-free results.
With these upgrades, Unified Color has reengineered its base architecture to significantly improve performance and expand the programs’ tool sets to offer additional fine control over global and local tonal adjustments. This new architecture powers a real-time processing engine that enables image adjustments to be visualized immediately while applied to the full image, not just a proxy or scaled down preview version. Additionally, new color-safe Dodge & Burn Brush and Tone Curve tools supply unprecedented 32-bit local control, enabling photographers to selectively lighten or darken specific areas without inducing color shifts, gradients or posterization.
“With HDR Expose 2, our new flagship application, the 32 Float v2 Photoshop plug-in and our entry-level HDR ExpressTMproduct, Unified Color is providing a complete range of fully optimized HDR solutions for professionals and photo enthusiasts looking to create true-to-life HDR images,” said Alfred Zee, CEO of Unified Color Technologies. “We’re proud to offer these powerful tools that demystify the HDR process and make it accessible to the widest possible audience.”
Additional new features include:
- Batch Merge and Batch Processing tools: Commercial and high volume photographers will save valuable time with the new automatic batch merging process which automatically groups and previews images from exposure brackets of any size and then merges them to 32-bit HDR files. After the merge, 32-bit images can be batch processed for final TIFF or JPEG output by applying user presets. Users can even choose to process the same image up to 5 different ways by selecting multiple presets. All batch merge and processing can be applied as a background task to further enhance workflow efficiencies.
- User-Definable Global Presets: Providing a one-click starting point, the presets can be completely customized to personal preferences.
- Restructured User Interface: Users are seamlessly guided through the ideal order of operations that ensures each available adjustment is applied at the recommended step in a methodical workflow.

It’s that time of year when the world is aglow with Holiday Decorations, so I thought it would be a good time to do a quick lesson on how to shoot HDD using HDR.
First off, of course we want to shoot these at night, only we really DON’T want to shoot them at night. We want to shoot them at dusk, that time just after sunset and before the sky plunges into total darkness. This way we not only see the beautiful lights we also get a better rendition of the building or houses them selves
Hotel Del Coronado
So right after sunset I headed over to one of the most spectacular places for holiday light in an old style traditional way, The Hotel Del Coronado on Coronado Island California.
I set up my tripod but before I placed my camera on it, I took a few seconds to measure the dynamic range of the scene, It wasn’t that wide but would take 3 images 2 stops apart. I actually did do a few sequences of 6 shots 1 EV apart but I will talk about them in a post to follow this one tomorrow.
In this first shot I measured the sidewalk in front of me and got a reading of 6 seconds and then I moved to the brightest area of the sky and got a reading of .8 seconds. I merely needed to connect the dots from there.
I shot at f/22 and ISO 320. I chose f/22 because I was hoping to get some star effects on the light and that really didn’t work out unless you look at a couple of the chandeliers visible inside the building. If I were to do it again I would have gone with just f/16 since the point source lights were really too far away and too small to get a good effect on them.
I used a slightly higher ISO because there was a slight wind off the ocean and I was hoping to not have to go with super long exposure times. Plus being the time of year it was there were a lot of visitors and I was trying to shoot quickly to keep them from ghosting the image.
Here is my first shot, shot right after sunset by a small bridge
I processed it in Photomatix Pro 4.1, using most of my standard tone mapping mix, Strength 85
Light adjustment natural, Gamma 1.20 and a little kick of white and black levels.
I wanted to be a little different this time so I did all my final adjustments in Lightroom instead of taking the image to Photoshop. The biggest reason was there were some angular distortions shooting the architecture. So I straightened up some lines and then just added a little Vibrance and Clarity and I was done. No need for Photoshop at all.
In the next shot I changed positions and this was shot about 20 minutes later
The lighting conditions were now the same ISO320 and now f/20 (no reason for the change I just hit the dial by mistake). But the times for the three exposures bow ranged from 30 seconds to 2 seconds, again I covered them in 3 – 2EV exposures, and again, finished up my image all in Lightroom.
I then moved inside to the lobby of theDelto the beautiful all wood lobby and the magnificent tree. Unfortunately due to fire regulations, they now have had to change to an artificial tree and as much as I miss the great real trees they used to display, they still do an absolutely magnificent job of decorati8ng it with a different theme every year.
I took up position on the second floor ( where I’m not supposed to be) and because I knew it would be an easy shoot, set my camera on AV mode and just did an auto 3 exposure 2EV bracket.
For these images I turned to finishing them in Nik HDR Efex Pro because of the fine detail present. Photomatix does detail just fine. But I enjoyed using Nik HDR Efex Pro for out interior shoot 2 months ago, so I returned to it here.
I didn’t need to do much to get a great image. Compression was 22% a slight exposure adjustment of -.65% added 8% Black and then changed the HDR method to Crisp at 10% and that was it.
Again I finished the image in Lightroom with just a few corrections and slight adjustments and I had a final image
I changed to a vertical camera position and shot this sequence, using the similar adjustments
Well of course I know you are curios so I did one other exposure and instead used Photomatix for the Tone Mapping. Again like I always say, neither one is correct but they produce such different results
I also included a single image to show what it would look like without using HDR for our HDD. It’s OK but just doesn’t have the reality that our HDR does.
And just as I was leaving I spotted this Vignette in a small staircase and just fell in love with the light it had. While I was setting up a Bride and Groom went up there and got a couple of snaps by their friends with their P & S cameras. I SO wanted to shoot them in those chairs. It really could have been a magical shoot but I didn’t have the lighting I would have needed to carry it off.
BUT I LOVE this shot. It’s not Christmassy, but I love it.
I hope this helped a bit to show you how I shoot HDD with HDR. I have been shooting the Hotel Del Coronado for the past 15 years. Without a doubt this has been the best capture ever. Thanks for coming along
One of the best features of Nik HDR Efex Pro 2 is that they have Adjustable control points. Control points allow you to change the effect and exposure balance on selected areas of the image. Most HDR programs in tone mapping allow you to make adjustment globally but don’t let you work on Local areas. Nik HDR Efex pro does.
So let’s take a look at how Control Points work.
When I first saw Control Points in Nik HDR Efex pro when it was introduced, I actually was a little confused by them. I thought they just worked like a circular selection tool in Photoshop with a feathered edge. No, they are far more sophisticated than that and the fact they show that circle is probably what makes it confusing.
So before we use them let’s take a look at how they work and then it will make more sense. First the point itself. It is going to look at the tone of what lies directly underneath it, so in our sample image, if the point was over a cloud or the white sky, will make a difference on how the effect affect different ones. It won’t only affect that tone but the bias will be to those or similar tones first.
Then you have the area circle, this affects how big of an area the adjustment works on. But again, this will NOT be a hard edge or even feathered edges since that would sitill give you a strange circular pattern on your image. So instead, the effect continues to be adjusted outside of that area to the tones that the center point is over. They just are affected to a smaller and smaller degree as it moves away from the center point. There may be a pixel totally on the other side of the image and not in the circular pattern that may be affected. But just in a much smaller proportion to what is contained within that circle area. This keeps the image very natural looking and not these big haloed circular areas put all over the image.
Putting control points to use
I thought I would use an image we used last week in the post about problems and how to fix them. If you remember from that post, we wanted to get our building the right tone of white. So taking that image into HDR Efex Pro, I was easily able to get that building to look correct; however certain other areas of the image were affected globally and now looked bad. So let’s use control points to bring those areas back under control.
Here is the image and the problem areas pointed out.
We’ll start with the large area of sky that is now blown out and has no detail. I am going to place a point there by clicking the “Add Control Point” button and place it over an area of open sky and I adjusted the circle out to cover a good portion of the area I wanted to affect. I lowered the exposure by .5EV and also reduced the white level by about 21%
If we go over to the adjustments panel and to the control point section, we can turn on the mask area (Pointed out by the arrow) to see really what areas and tones are being affected by this adjustment. This is where you really can see better how things are affect and how while the areas that have the largest amount of the effect applied to are within the confines of that circle. It really is not applied in a circular fashion. We can also see in the adjustment panel that this control point affects 31% of our total image area.
Now I can go ahead and place more control points throughout the image and adjust each one of the separately to really bring out that areas so that it looks best.
With all of my control points in place and the mask on we can see the areas of the image that are affected by our control points.
One thing to take note of, see inside the garage where I am showing the active control point. I placed the control point on a midtone of the red Life preserver.
In the next image I show how the control point changes the affected area by moving the control point to dark area of the wall.
And here is our final image with all the control points in place showing how those point are now corrected without changing the global look of the image or how the building exterior looks.
Control points are available on various other Nik offerings like Sliver Efex Pro, Color Efex Pro and Sharpener Pro 3.0. Just their operation may vary depending on the program. But it sure is nice having that control.
