I noticed the other day while taking pictures with a friend of mine who has a D50 ( I have a D70) That his exposures were a lot brighter than mine. I always knew that my camera took Dark pictures. The only differences were the lens and speed light. He has a digital lens and I have a 35mm Nikon lens. He also doesn't have a speed light and i have the SB600. Am I doing something wrong or does the D70 tend to expose towards the dark side? Thanks for the help.
