These were taken with a 6d and a 17 40 I used timer, mirror lock up, tripod and focus stacked and still didn't get the sharpness I was after. What would you think I needed to do to get them sharper? Was it me or the lens?
I looked at the histogram on the 2nd one, and found it underexposed, with no data in the highlights and little in the midtones. I think there are situations where focus stacking on landscapes work, but the movement obstacles to overcome make it difficult to use. By comparison this was one shot, ISO 100, f/7.1, 1/8, in mixed light. Helen trip07092018_650.jpg If you do focus stacking it helps to make duplicates of your images as layers, then only blend either the originals or the duplicates, then if there are areas that are unsharp, create a merged layer with a white layer mask and move one of the unedited layers beneath it. With a black brush paint the sharp image back in.
