There are times when we come across a scene that we, as experienced photographers, know has an exposure range that is beyond what our camera is capable of recording in a single frame.
With that in mind, and looking at this image above, do you think it is:
(A) – A multiple exposure which has been manually blended to combine the best areas from each exposure?
(B) – A Single RAW image file that has been processed multiple times, and then manually blended using masks to create the final image?
(C) – A multiple exposure that’s been run through an automated HDR process like PhotoShop “Merge to HDR”?
(D) – An in-camera HDR?
Here are the original RAW frames from this image:
Back in the days of shooting slide film, you had very little choice on how to solve this kind of exposure latitude dilemma. You could adjust your composition to eliminate problem areas, or you could use lights or reflectors to bring your darker problem areas of the scene into balance with the brighter areas of your shot. In some cases you could possibly use a graduated neutral density filter to help solve the problem, but that didn’t offer much help if problem areas were in multiple locations throughout a frame.
With the advent of digital photography, we now have some very handy methods for solving dynamic range issues in scenes that exceed what our camera is capable of handling on its own. These methods include blending multiple frames with masking techniques using either multiple frames, or multiple-processed versions of a single RAW file. There’s also the grand-daddy of all solutions, the automated HDR software processing of multiple frames, each with a different exposure value. This is a great option for scenes which have lots of details and where the light values are mixed among fine details, for example inside a high-contrast scene like a sunlit forest with lots of shade. The big problem with HDR and Tone Mapping multiple exposures is that some people simply use the technique to wander so far off into the “Electric Kool-Aid Candyland” that all sense of reality is tossed aside.
My Nikon D800 camera is pretty nifty, in that it will do HDR processing for me in the camera. I don’t even need Photoshop to make HDR images anymore. (Not that I’ve ever really made that many HDR images to begin with.)
Well for those of you who are wondering, the answer is Read the rest of this post »
