So I'm aspiring to be a better photographer and I figure the best way to do that on an amature level is to isolate some of the things that go wrong and learn to fix them. I'm still pretty hesitant with most of the manual setting on my Canon SD 700 but I'd like to improve on that. So here it goes, sometime I find certain shots grainy, I don't like that so I'll try again but "the" shot Im trying keeps coming out that way, here's a tame, albeit typical example.
I assume its related to the lighting, what should I do here? Change the ISO speed?
