I've been asked to use focus stacking on a jewelry shoot to render all parts of the items in sharp focus. Obviously I've never done that before, and even feel a bit aprehensive since I really like to throw uninteresting parts of the items OOF. Anyway, a quick google search returned a few free softwares and Helicon. I'm interested to know if anyone here uses this technique and would recommend a particular software (preferably free ) and of course, any advice would be very greatly appreciated.
Thanks in advance.
