Nice read! Added ISO discussion on my first post.
As an update for myself, I started shooting in manual mode two nights ago (my night shots of my 335 are in the picture forum) because I needed too in order to get the shots, A, S, or Auto just didnt cut it. Ive been playing around with it a lot more and I now can somewhat put the pieces of Apeture, SS, and white balance together to get a good shot. Now I just need a strong editing software to perfect the pictures.
