Hi, I've been hired to do a number of product shots of coffee beans bags (shiny material) and have been running into problems. In addition to a tricky reflection, the bags are easily wrinkled and don't hold their shape very help. Its very difficult to remove one wrinkle and not create another. Thse are desktop shots against a seemless background. I'm not the most experienced product guy, does anyone have any tricks/suggestions to have the bags appear at their best?
