Evaluating Imaging Performance @ 17mm, Single Frame vs Stacked: Bristlecone Log Low View
Based on extensive field shooting, it was seen that using f/13 versus f/9 added only marginal depth of field, did little to improve corner quality and degraded the entire image from diffraction, seemingly more than usual from f/9 to f/13.
The question thus arises: how does one deal with outdoor scenes in which the depth of field of f/22 would be desirable, but f/22 is unavailable and both f/22 and f/16 would degrade the image unacceptably (by diffraction)? The answer is focus stacking.
Focus stacking using Zerene Stacker. See tutorial/how-to in Making Sharp Images.
