Using the Histogram to Ensure you have covered the Dynamic Range of a Scene

HisogramAs I discussed in this article: How many Exposures are enough the most important part of the -How many exposures do I shoot – is the fact that you need to cover the entire dynamic range of the scene. As the article pointed out the spacing between exposures was not AS important as covering the entire range.

In this article  Measure & Exposing for HDR I told you how to meter different areas of the scene to know the range of shutter speeds you would need to shoot to cover the dyanmic range. But even though it’s a good way to get you close, there still can be some margin of error because of course we know…sometimes the meter gets fooled. Continue reading »

Depth of Field – In Depth

Depth of Field – In Depth

Everything you wanted to know about Depth of Field and some things you didn’t but you will be glad you did

So you may think you understand Depth of Field (DOF) but do you? Let’s try to confirm what you do know and maybe show you a couple things you didn’t.

What is Depth of Field?

Let’s start with a definition: Depth of field is the total distance that is in “acceptable focus” from our actual point of focus. Let’s clarify that definition further because we artistic minded hate reading definitions.

When you focus on an object, you have a “point of focus” that is the only part that is 100% sharp and in focus, then you have a “field of acceptable focus” in front of and behind that point. That area is the total Depth of Field Continue reading »

Advanced Metering

Advanced Metering

In the blog post “How to Shoot in Manual” I gave some very basic information about where you meter is in your camera and how to use it. In this post we’ll talk really In-Depth about your Camera’s meter

and how to get the most out of it and when to know when it is lying to you and how to correct for that.

What type of Meter do we have in our camera?

The Meter we have in our cameras are known as “Reflective” meters. What they actually meter is the light reflected off of our subject, what we are shooting. This is different than Hand Held Meters. While those meters can be used also to measure reflected light, they normally measure the light source itself also known as “Ambient” or Incident” light and are mostly used to measure the light from Strobes/Flashes that a reflected meter can not.
