Hi! everyone, I am a new member who has been looking at the answers and info here for some time. I am also the new owner of a D5100. Yes the price has started to drop as inventories are being depleted in anticipation of the D5200. I have a question. When I transfer my files to a computer for processing I can open an information window that includes all the file data saved as part of the photo. One of the items listed is "exposure program: 0,1,2.....). The number changes as the program used to take the picture changes. Is there a list that compares this number to the program used on the Nikon? This info would be helpful as I learn the full use of the Nikon D5100. Thank you
