As some what of a photographer I agree with you 100%. If your taking stills, dirty and ruff or not your hands should not be in it at all. Use something a little more appealing than a pink wrinkly palm to take your photos on. Try a rock, a piece of wood or branch, maybe a leaf. For lighter objects like silver you should have a dark background. For darker objects like dark green relics you should have a lighter background. If your taking a video I would not pay to much attention to it, if your shooting a lot of images your hands will get in the shot once in awhile. So don't worry about it, but if your shooting stills don't use your hands as a background.... Please !!

Keep @ it and HH !!
