Hi, i'm just new on using the DSLR, just want to ask for advise on what to do because whenever I put my camera on shutter speed dial, if i take a picture, color will be very dull, a bit yellowish, and that's why i still use auto whenever i take shots, but i want to start using a different approach. Please advise how to get the best results when i'm on shutter speed dial or apperture. Thanks
