Overexposure. I need help!

[janeqb]

Hi, newbie here who just bought a Nikon D50. I have so much reading up to do and need to learn more about my camera and obviously brush up on my photography skills. I thought I would ask for some quick tips while I continue to read my manual.

Many of the pictures appear to be overexposed no matter what mode I use. I have played around with different modes (S- shutter priority especially). I know I must be doing something wrong. When set on Auto, some of the pictures still appear too bright, leaving highlights all white. Green trees are washed out and yellow in some pix. I know, I'm dense as all get out!! This is my first DSLR and I know it's just going to take time and patience. I'm a bit embarassed even posting this. I just didn't think this would happen in auto mode!

Thanks so much!
