Grainy photos and troubles in macro

[Myka]

Thanks for all the ideas! I installed the software from my camera, and it really sucks. Or maybe I didn't figure it out...

One of my problems is that no matter what settings I try on Manual Mode the pics are super super dark, so i set ISO at 800 and then it's "normal" brightness, but pixelated. I tried somemore photos and got the best ones just setting everything on auto. Of course... *rolls eyes*

I will try some of these other programs. Thanks!
