Tip number deux - ISO

Tip number two- master your ISO. ISO is the same thing that film speed used to be, back in the "dark ages." I have no idea what ISO stands for (like I said, I'm self-taught. Hold on, let me do a google search..........)

OK, voila! WikiAnswers says "ISO stands for 'International Organization for Standardization' and is taken from the Greek word 'isos', meaning equal. See ISO has replaced the older ASA designation. "

What does this mean to us? Nothing. Who cares? No matter what ISO means, what really matters is understanding how to use and apply it. ISO controls how light or dark your picture is (the "exposure".) The higher the ISO, the lighter the picture. Which you would think would be the answer to all low-light situations. But, there is a negative side to having a high ISO- the higher the ISO, the grainier the picture.

So here's your assignment- 1. Set your camera on manual (even if you haven't learned to shoot on manual yet). 2. Figure out how to change your ISO on your camera (look for a button on the menu or on the camera that says ISO), and 3. Stand in one indoor place and take a picture at each ISO setting. This will show you how ISO can affect your exposure.
