I shoot in manual mode most of the time, but will use Aperture Priority some. I shot for an ice hockey league a few years ago, and used shutter priority with exposure compensation, because the light varied depending on where in the rink my subjects were, so with fast action, I couldn't keep up with manual, and I was shooting at ISO 3200, so I needed to keep the histogram to the right, to limit noise. I never use Program or Auto mode.
