Dun worry, Lazerlord is a established photographer, I'm sure He
is willing to give you some pointers if you ask. When I 1st started
"shooting" around with my retired A70, I jumped the boat. Without
much knowledge, I went straight into underwater photography
. Most of my
beginning photos were either greenish , blueish or with lots of
back scatter due to the lost to red,yellow, orange etc. and
particles in the water. After shooting lots more and reading up and
advice from old birds, can see my own progress.
And unfortunately desiring for more accessories.
Just shoot more, and try to figure out whats wrong with the pics.
The forum at www.clubsnap.com is a very good site for info. btw i'm
using another nick there. Shoot , shoot and just shoot. 
I'm only a amatuer, Lazerlord is the man . Rite bro ?
