Thanks for the advice. I took it in the first time you pointed it out and I added a comment in the PDF (right away) telling folks about it and where to get it . I also experimented with it, so I am up-to-date. That being said, I like doing it the way I do it, and others are free to do the same. I have a fast computer, and the retouching part of things takes longer than any amount of stacking calculations. If I have two many finished stacks ready at once, I feel pushed. For me focus stacking is a recipe in patience, and I appreciate that about it. Also, giving Lightroom too many tasks slows it down, and I tend to do other things while stacks are being processed. Trust me that I am not wasting any time.
