Well, thanks to Kayla Lamoreaux of Digiscrap 101 I found a link to muddyboots where I found a link to this awesome site.
There is a SimCam where you can try out different apertures and shutter speeds to see what effects they have on the "sample" image. I found it a lot of fun as well as learning to understand the applications.
All of the links I have given you today are packed full of tutorials to help everyone from digi scrappers to hybrid scrappers to beginner photographers so I highly recommend you go take a look for yourself.
