If you are taking lots of shots each day then I suggest you should come up with a system that would make your work faster and easier. If you’re still wondering how you should work with your photos, Stilllifewith.com has a quite interesting article on food photography workflow.
“I try to get the photos onto my computer the same day, hopefully within a few hours so I can remember what I was going for (and so I don’t accidentally forget and format the card as I am trying to get into a habit of it everytime I start shooting). I copy the photos onto my machine simply using Finder (I’m on Mac). Then I start up Adobe Bridge and do a quick browse of all the photos I’ve just taken. Before I touch any of them, I batch rename them based on their content.”
