One of the hazards of being a photographer is, running out of harddrive space.  One food shoot can easily produce 100 images and at 7MB an image, with ususally 3-5 shoots a week… well you can do the math if you want.  I’m lousy at math.  I just know it’s lots.  And lots. When I shoot with a 5D MKll the images are 28MB each.
