I have Nikon D3100 with DX 18-55mm lens. Can you please help me fix the problem of the background being too dark while photographing jewelry? I tried many settings and each time I have problem with the background being too dark. I use some programs on my PC to make the picture and the background lighter, but the object is also too light and that makes the object look unreal. I calibrated the light using the function in the camera with a white paper sheet, but that doesn't help too much. I used a SANOTO 12"x 8" light box, which has plenty of light, but the photo comes with grey background instead of white.
