Last October while walking around on the San Francisco Peaks near Flagstaff, I saw this scene where almost all of the aspen boles overlapped leaving very few gaps. This fall, I revisited the spot and redid the photo with a focus stack.
Did you turn OFF the sharpening in Raw before the auto blend? I find in my classes that so many forgetting to do this. The sharpening creates an artifacting that fools the blending algorithm to choose/mask pixels that are not actually the sharpest in the stack...
Thanks for the comments and suggestions.
Mark, I did not have sharpening at 0, so i just reset the raw default for next time. Thanks for the tip. Now if we can keep leaves from moving from shot to shot ;-)
