I have set up a crude studio, mainly because I'm taking photos of a lot of RC car stuff to sell, just to give the photos an uncluttered background. I went and bought 3 clamp lights and 3 23W fluoursescent bulbs. Grabbed some posterboard(I know about the seams, they did not have a large size). Here is a picture: The yellow balance looks way off, if I use the flash, it looks better. Here are two examples.... I'm holding the 3rd light at 10-o'clock just above the camera lens pointing down at the subject. Manual mode, 1/60, f/5.6, WB flourescent, ISO 100, kit 18-55 lens @ 55mm focal length. No flash: With flash: The picture just seems yellow to me without the flash. But I think the no-flash picture looks better as far as contrast.... I know I can use the flash to make it look ok, but I want to learn what's causing the problem so I can correct it. I assume the bulbs are the cause of this? Do I need a "special" bulb for these types of photos?
