In the past my only attempts at exposure bracketing were with a film camera and were limited to one or two additional images shot with minor variations in f-stop or shutter speed. Then, when developed, I would select the best image and put aside the others.
All that has changed with digital.
Recently I had a chance to explore a slot canyon in northern Arizona. Typical of many slot canyons is the significant variation in light from very deep shadows to brilliant sunlit canyon walls. My best images in these slot canyon have always been compositions that minimize this large variation. But with automatic exposure bracketing and the many available software packages to process the images it was time to give HDR a try.
With just a few images and using Photomatix HDR software I was able to bring out the subtle colors in the deep shadows of the lower canyon wall while capturing the more brilliant colors in the sunlit upper wall.
A second HDR image is able to capture both the well-lit areas and the shadows as twilight approaches over Lake Powell north of Page, Arizona.
