I made a cheap photo studio in my guest room, and Have a TON of lights. So bright almost hurts your eyes, and heats up the room VERY fast. Lots of white sheets also to reflect light more. However, when I take a photo with my digital Nikon D50 set on Auto, or Portrait setting, the photos turn out to dark. Looks as thought I have no lights or very little lighting. (I am not using my external flash) I don't know what to do, or what I'm doing wrong. I am not very good with the Manual setting so I don't know if that would help. I'm attaching a photo that I took of my set up. A few diffrent angles. I have 2 100 watt lights, and 2 Holegen lights. I have white silk in front of the holegen lights to diffuse them. No difference in photo if I remove the silk. If anyone could give me a few tips, that would be great! thanks.
