Canon 1Ds Mk II, Canon EF 50mm 1.4. The camera was set to Av mode where I control the aperture and the camera chooses my shutter speed. I set the aperture to f/2.8 to get relative sharpness all around. I shot this directly overhead so as not to have any shallow depth of field. Also shooting at larger apertures got rid of the vignetting. f/4 would have done a better job but at this time of the day, light was limited. The sun had dropped behind the trees before I attempted this shot. I dialed down the exposure compensation to -2/3 because it was important to me to expose the white golf balls correctly. If I kept the exposure bias on zero, then the artificial turf would be quite brighter, over exposed even, while the golf balls would simply be unrecognizably blank and lacking any detail.
