congratulations, you just found out one of bodybuildings secrets. A smart woman once told me that bodybuilders should think like magicans, makin illusions. Your goal is to make the illution that you are well muscled, defined and with the right proportions. This you do with lighting, put on tan, and so on. Thats why many bodybuilders look better on pictures taken with special lighting, than if they stand in front of you. its magic.
