This and your combination with PS stacking seems to work.
Did you ever try Zerene for this, or has PS slowly caught up with the dedicated stack s/w?
Thanks Colin,
I tried zerene a few years ago, conditions were different, I used 36mp raw files, and a 150mm macro therefore a shallower dof, also focus was adjusted manually using the d800 live view. The processing was slow and had many odd artifacts, I did not continue my efforts
This time, with the x-t3, the experience was much smoother, and ps did a good job with little effort. I noticed that even with jpgs , and only 20 images the file grew to 1.5gb while doing the stack, my machine has only 8gb , I doubt I can tackle much deeper stacks in ps.
