Lesson 1: Learn what your camera does (for those of you using SLR cameras)

A friend sent me this link today and i think that it might shed a little on what all those settings do on your camera that you never bothered using. (the green square or the little pictures work good enough for you, right?)

Because i am lazy, I'm going to let this explain Aperture, Shutter Speed and ISO for me.

This will give me more time to procrastinate before writing my next post: MOVE CLOSER. (or, Nobody needs to see grandma blowing her nose in the corner of your picture)
