If… your 32 bit image looks pretty good, most likely your scene did not need HDR
If …your 32 bit image looks really bad, chances are you captured a true High Dynamic Range scene
I don’t know how many of you stop Photomatics at the point when it creates a 32 Bit Image just before you go on to tone-mapping. If you don’t then maybe you should (it’s on the screen when you make your alignment and de-ghosting choices)
The 32 bit image can really tell you a lot about what you captured and how in the end your image will turn out.
Here is a 32 bit image of 3 exposures +/- 2 and it is somewhat fitting. As you can see it doesn’t look too bad right now, but the final result really wasn’t that much different than the 0 exposure.
While on the other hand, this 32 bit image shows that there was in fact a wide dynamic range that could not be capture in one exposure.
I’ll be back tomorrow with more on my Salton Sea shoot.
Hope that helps,
