Here's a shot of my sister right by the window, the shot was taken in RAW on a Digital XTi and Canon Digital Professional was use to edit the RAW file a few tweaks on lighting, white balance and RGB. Have I properly edited the picture? It seems as though there is more noise on a RAW file, could this be due to my editing? shot on 50mm 1:1.8 Aperature at 2.0 E1/40s ISO 400 let me know what you guys think, any tips on how to improve the picture editing and what not. thanks.
