This is actually my second post here, but it certainly won't be the last. I work for a virtual skincare and cosmetic store BuyBeauty, and I just recently started doing some of the product photography as well as managing the shown inventory online. Well, my boss bought me a (in my opinion) cheap setup for a lightbox and lights. He got it on eBay, and it's just not really up to standard. My problem is that I can't often get the background washed out enough to be usable without editing it in photoshop, which is what I was trying to avoid when I asked him to buy a lightbox. I've tried everything. I've tried playing with the exposure, shutter speed, everything. The background looks white near the bottom but gets grey as you go up. Any ideas???
