NanoReefWanabe, thanks for the compliment ! I wish I could help you but I just keep snapping shots with dozens of different settings. Sometimes I will get one nice shot out of a hundred. That's the great thing about digital cameras ! It does not cost to develop your film. I used to spend a small fortune when I used to use my 35mm SLR.
Some tips I can give you :
Try the same shot with and with out flash.
Always clean your glass before shooting.
Shoot at an angle when using flash.
Keep your lights off in the room while shooting.
Pretty basic stuff , I know. You are probably doing it already.
