i'm new to the G2 & new to photography in general.
anybody have a good site where i can learn about aperture, shutter speed & everything else? specifically, i'd like to learn how to best use the setting on my G2 (M, Av, Tv, P & the others)... basically, what situation calls for what setting? when do i NEED a tripod? when do i NEED to use flash? questions like that.
besides that, i'd appreciate any general tips about how to use the G2. i found the histogram setting tip to be very helpful... thanks.
