exposure tips please
I recently took the below shot using my 7d and 100-400 at 400mm handheld. When doing bird photography, 90% of the time I use AV mode with the lens wide open to give the maximum shutter speed possible. To meter the below shot, I used evaluative metering and the swallows came out really dark. I've managed to rescue it a bit in Photoshop, but have lost detail and colour on the birds becuase of this.
With hindsight I probably should have used spot metering and AE lock. Would this have been the best way to expose this sort of shot or are there better ways?
