Is there a good resource/article out there for the basics of photo taking for the aquarium?  I've got a Nikon d3100 that I can't figure out.  I breezed through the manual once awhile back.  I don't understand what any of the buttons or settings do.  I see people talk about white balance but I don't know how to do that either.
Thanks
