Frank, I've been stacking a long time and really enjoy it, 'though by no means an expert. Stacking is for the few and the most will not care for it. My conclusion comes after leading 3 workshops on the subject, several with my photography club and one at a regional photography seminar. It was always gratifying to see photographers become excited and speak enthusiastically after the presentations. Yet, to this day, in my photo club which has 100 or more members, nobody, except myself, does any stacking. It is definitely not a technique for the faint of heart! (Should I say "lazy" of heart?)
