I presumed it would be fullscreen based on the amount of people doing it, so I assumed it had something to do with the differing aperatures in the test I did, I was just thrown for a loop when I read someone else describing it this way. I meant to try it with a 50, but it wasn't in front of me at the time, and I didn't feel like getting it out (what, me lazy?). Either way, that explains that. -- http://www.infotainment.org <-> more fun than a poke in your eye. http://www.eighteenpercent.com <-> photography and portfolio.
