Could someone please explain the differences in these and what they are suppose to do. I know apature is how much light is allowed in, and shutter speed is the speed of the shutter(duh) I assume exposure is basically a computerized way to force the picture to be lighter or darker? And ISO, I know the higher settings allow more light in...

I'm just curious... I've realized my Panasonic FZ-20 will set itself to F4.0 when on macro. I tried taking a picture of something(off macro mode) later on with a low then a high apature setting, and the higher had better color. So, does a faster shutter speed also allow less color?

The Exposure Triangle - http://digital-photography-school.co...l-photography/

Also have a look and play with the exposure calculator, lets you play with the all three values to see how they interelate.

The Triangle ISO link above.

Whomever wrote that article is incomplete in stating:

Aperture is the size of the window. If it's bigger more light gets through and the room is brighter.
They should state that the larger aperture opening has smaller f numbers as this could be a little misleading for the beginner.

Which is why of the 3 articlesIlisted it 3rd.

By the time you have read the other 2 you will already know about larger apertures-> smaller f number
