Extreme macro does not mean bugs only, it can be applied to product photography, too. Here is my first attempt at shooting a watch at 2X with stack and stitch technique. Though it is not as big as others, it is big enough to have a decent print size -- 40 inches by 40 inches (or 1m by 1m) at 300 DIP with original file. I need a CPL filter to reduce reflections, so when that arrives, I will try again.

Total 1125 images, 3x4 = 12 frames. Again best viewed on EasyZoom
