ARGH! I have been trying to work on my photography course, and I just can't get past the f-stop information. (Which means I haven't gotten very far because f-stops are at the very BEGINNING of the course!) It totally throws me for a loop. So, I have resorted to searching the internet for an easier explanation. Ya know! F-stops for dummies! LOL And most of it still sounds like gibberish to me.
I wish some of my photography buddies lived close to me so that they could "splain" it to me in person!
