Aperture and I.S.O.

Watch this week's video by clicking the link at the bottom of this post.

The Basics:
Aperture is the diameter of the hole in the lens that light enters through, and it determines the brightness of the image. The larger your aperture is, the shallower your depth of field will be. Aperture is expressed as f/a number, and a larger aperture is expressed as a smaller number.
I.S.O. is how much light is needed for your camera to produce an image with the proper exposure. The larger your aperture is, the lower you can set the I.S.O., which will result in less grain. Grain usually becomes noticeable when using an I.S.O. of 1600 or above.
