just remember, if you move one setting one way, another setting must move in opposite direction to compensate for it (if the settings are good to start with).
So for example:
you are shooting in AV at f/4.5, speed 1/100, ISO 600.
The image is way over exposed. There are two things you can do
1 - move the f/stop to a smaller setting (remember, f/stops are backwards, higher number, smaller the setting). So you can move the f/stop from 4.0 to 4.5 (or even the next one), this will lower the exposure.
2 - lower the ISO.
A good basic thing to know, what these things are doing
F/stop is telling you how much the aperture is open. The more it is open, the more light gets in.
The speed is how long the aperture is open, so the faster the speed, the less light gets in
ISO is how sensitive the sensor is to light, so a higher ISO, the more sensitive the sensor is.
These three things work together, if one is moved, another one (or both) must be adjusted to compensate.
