Just a quick tip. don't waste your time deleting from memory card and checking photos on the spot, keep it for later one, the more delete/write cycles, the shorter the memory card and the higher the risk of losing all your shooting .....
In location just shoot, Then once at home download everything, don't delete anything , don't do cut/paste, just download everything then format your card in the camera, I have learnt it the hard way, it's rare it happens, but you imagine the disaster when it does happen.
Once the photos are on a hard disk, feel free to delete the ones you don't want, just resist the urge to delete blurry shots on the shooting location
