I'm interested in taking sporting images, but am unsure how I go about setting the shutter speed, and aperture.....I took some shots yesterday, but struggled to get some consistency with the shots. it was late afternoon, and I was facing toward the sun. what is the best aperture to select and shutter speed for those shots. I think I was using 350 and f5.6 for some reason my camera wouldn't let me go down to 4.5. If i tried to go to 500 the shot would be too dark. Also when taking a shot in full sunlight what is the best method of shooting. Is it better to speed up the shutter, or decrease the aperture size.
