If I remember correctly someone posted a link longtime ago for an official Canon site where you can play with a virtual DSLR - such as changing aperture, shutter, and it shows changes in a virtual shot.
Does anyone remember what I'm talking about? I thought it was Canon Digital Learning center but its turned into a paid class link...
I have 2 friends who just picked up Xsi's and I thought it would help them greatly...thanks in advance!!
