Sorry about he delay in replying. It's been a bit busy in the studio this week.
Covering a few of the topics a page or so back.
Slobodan, a tip for gluing rings. Don't use wax use hot glue. The Bosch hot glue guns with their own brand of glue stick can deliver a tiny dab of glue to the ring shank. It flicks off afterwards with your finger nail or if stubborn, a little lighter fuel loosens it. Only on the metal! never on precious stones or pearls. Ever!
Yes I shoot MF. Yes I also use focus stacking and tilt/shift and some times I use a combination of both. It depends on the shot.
