Post-Processing: A Shadow Recovery Example

Note that this is an older article from 2012. While the concepts are largely the same with contemporary cameras and software, some aspects of the article are now a bit date.

(In another forum someone asked a question – actually, more like posed a challenge – related to how much usable detail and quality could be extracted from a raw file that contained areas of very low luminosity, as could happen with a badly underexposed image or with an image of a scene with a very large dynamic range. Since I went to the work of responding and illustrating my response, I figured that I might as well share it here, too. With minor revisions, here it is.)

First, I actually have a “real” version of this photograph in which highlights were slightly blown, but which I preferred to use since I could bring them back in post and get a bit more shadow detail to start with. (It looks a bit bright to me as an on-screen jpg, but it makes a fine print.) That photograph ended up looking like this:

Morning light slants over the top of sandstone cliffs above early autumn foliage in Kolob Canyon, Zion National Park

This photograph and the other I’ll move to below were both shot from a tripod with a Canon EOS 5D Mark II at ISO 100 using the Canon EF 24-105mm f/4L IS at f/16. While the “keeper” used for the photograph above had a 1/4 second exposure, the example I’ll use below was shot at 1/30 second.

The exposure challenge in this scene was the very large dynamic range between the bright spot of sky at the head of the canyon and the much darker colorful foliage in relatively deep shadow in the foreground. Exposing for optimal quality in the foreground would completely blow out the sky, while exposing for the sky would necessarily grossly underexpose the foreground.

I originally thought that I might like to have four bracketed exposures in case that would let me produce a better final image via layer blending, but it turned out to be unnecessary and the final image (as shown above) has a single source file with no blending. However, this means that I still happen to have one very badly underexposed (by three stops) version at 1/30 second which I’ll use here as the starting point for what I plan to illustrate in this post. Follow along with me and see what I can do with the very underexposed version of the file…

Selecting This Year’s “Favorite Photographs” – The Third Cut

I’ve taken one more step in the process of whittling down the original candidates for my “2012 Favorites” post –  the number now stands at forty. This still seems like too many, but it become harder to give up images at this point! (In fact, there are a few I removed that I really want to put back in!)

If you are interested in seeing them a bit larger, you can open the image and see it large enough to see a bit more detail. I’d be interested in your thoughts about these or even about some that have been left out.

Selecting This Year’s “Favorite Photographs” – the Second Cut

I’ve eliminated another 50 photographs from the running for inclusion in my “2012 Favorites” collection that I’m compiling for release sometime in the next week or so. It already hurts to pull some of them, but I still have way too many! Here is the current list of contenders:

I’d be happy to hear from anyone who has thoughts on this or who wants to suggest a favorite.

The Task of Selecting the Year’s “Favorite Photographs” Images

It has now become an annual ritual (obligation? ;-) to share a list of annual “best” or “favorite” photographs at about this time each year. I prefer to refer to them as my “favorites,” since it is very difficult to truly know which are “best.” Sometimes understanding that takes quite a while – photos that seemed amazing at first lose their magic and others that seemed less special grow on you.

So, how to do this? I exposed perhaps nearly 10,000 raw files last year. Most of those will never see the light of day. Of these, I was willing to share them at a rate of about one per day, though some will still be coming up here as “daily photos” for the first time in 2013. So I’m guessing that I might have 400 images to start out with. My target is a dozen photographs, but I’ve never distilled in quite to that point, and about 20 seems more likely.

My first step is to take all of the photos that I have shared online (or plan to share soon) that were made in 2012 and put them into a collection in Lightroom. I make a quick scan through these and start by generously giving anything that catches my eye a starting 3-star rating. That’s what I’ve done so far… and I have 119 photos!

The next step in the distillation process will be to go through those 119 photos and look for overlaps, images that I have a soft spot for but which don’t really work as well photographically, and photos to represent a certain diversity among the work I’ve done. I’ll share the results of that process here, too, once I complete it.

From that next selection, I’ll have the hard task of making the final cut.

If you have opinions about any of the photographs you’ve seen here this year, I’d love to hear your thoughts.
