i set my camera to the A setting, and I was using the command wheel (the one on the back, not the top) to change the numbers when i looked through my viewfinder. The numbers are changing, but I don't see any change in the depth of field. I put my hand in front of the lens, but far enough for it to focus, and my hand and the background were both equally as focused. What am I doing wrong?
Oh, one more thing: how do aperture, shutter speed, and iso play into each other? How should I adjust them to compliment each other?
Thanks in advance!
