Hi, glad to join this forum! I have a Canon EOS 350D and I am doing some product photography, without using any flash. I have a Cubelite 6x6x4 ft (you know, this "box" made of nylon that diffuses light evenly) and I am taking my shots with white paper roll as background. My PROBLEM: I can't get the white balance right! I set up the lights (4x500W Tungsten) outside the box, 2 left and 2 right, then I take a shot of the white background and it does turn pretty dark on the screen of the camera. I set this as a reference image for the white balance, place the dummy with the clothes in front of the background, take the shots and they all look as the dummy is in front of a medium grey background!!! But I have shown the camera what the white/reference should look like!!! Am I doing sth wrong? I am not a pro, perhaps not even an advanced amateur but I think I am following the instructions of the manuals. Any advice please??? Thxs in advance!
