A Few days ago I asked for help as I had lost my settings for my camera 1d mk3 and Received a couple of replies which was most appreciated however the settings were nowhere near my originals so if anyone can help I would gladly send £20 for a drink. Really am clutching at straws but so disheartened thanks
that should give you a good idea on the setting that you've used in the past 
, you could open an old shot in the programs Canon Zoombrowser or DPP and look at the shot settings in there
