Here I tell you how to stack landscapes with movement in Zerene Stacker. Zerene Stacker is a focus-stacking program that does a very good job at stacking. In particular, it allows you to override parts of the focus stacking algorithm using two methods, and I will tell you how to use these to deal with areas where there is movement for landscape photography.
