I just received my Nikon D5100 yesterday & after shooting a couple hundred photos I noticed quite a few have a pink cast to them. I switched the white balance to incandescent which helped some of the time, but in others made it worse. I've been using the Nikon D3000, so this was to be an upgrade, but so far I think the photos on my D3000 have better color. Any ideas? Do you think this is a problem with the D5100 or I just got a bad one? Debating if I want to keep it or just return it & go back to my D3000.
