Hi guys, i'm new so be nice

Got a dilema which perhaps you could help me with.

I have a FinePix F610 camera. I also have a number of Tropical Marine fish which i'd like to take pics of. Problem is I dont know my aperture from my elbow or shutter speed from my shoe. I'm just trying to get decent pics with the AUTO mode (and AUTO-MACRO mode) but with limited success.

Can anyone help out or give me a few tips?

I've included one of my better pics below of 'Nemo', as you can see it's still blury! It's taken me ages to take it 'that good' and i've taken hundreds since and they are no where near as good.

Help appreciated before i go completly bald!

Thanks,
Gary
