F/stop Chart

Here is an F/stop chart created to help in figuring Full, Half, Third & 2/3 settings for your Aperture.  A trick to memorizing the full stops is to remember the numbers 1 & 1.4 then double them(approximately) & alternately until you get to 64!  I'm still learning these myself but I hope this helps!

The Sunny 16 Rule:

If you don't have a Light Meter, Here's a great way to set your Camera Exposure outdoors on a SUNNY day! It's called the Sunny 16 rule... also known as the Sunny f/16 rule:

The basic rule is, "On a sunny day set your aperture to f/16 and shutter speed to the ISO film speed."

Example If the sun is shining and your camera is set at an ISO of 200 you can use an aperture of f/16, set shutter speed to 1/200 or 1/250. An ISO of 400 @f/16 would require an aperture of 1/400 etc.

In the same way if you remember these numbers for other lighting situations, You could shoot anywhere without a meter with as close to the correct exposure as possible!
