Nice. When using DSLRs, it is all about learning to shoot on manual. I would pick up "Understanding Exposure" by Brian Peterson. It's a great book to help you learn more about exposure and aperture.
What glass do you have for the XTi?
Glass? Is that the lens? I think its a 72mm telephoto lens. Im using the manual mode, but I'm having a hard time figuring out what shutter speed, ISO, and aperture size to use. I looked online about it, and it helped a little bit but I'm still not completely sure. What confuses me is that aperture controls the ammount of light exposed, and also the depth of field?
Here's a scenario: Friday night, I was at my school's homecoming game trying to take pictures of the players and then people on the stands. One buddy tells me to set it to Aperture priority and another tells me to set it to Tv(Shutter Priority?), set the ISO too 800-1600, and have shutter speed at 1/60 to 1/125.
Not sure to do. And how do I adjust the aperture size on manual?
And here are the results:
