SmugMug's Proof and Retouch Feature is useful even if you process your files perfectly ahead of time, and don't plan on retouching.  Why? 

Because SmugMug empowers your customer with the cropping knife, you can be certain, with Proof Delay turned ON, that your customers have made "just the right crop."  Set your galleries to a proof-delay between 1 and 7 days.  When the customers order, you'll get an email from us.  Go to the order in  your control panel, and verify that the crops are good. 

Sometimes we get asked, "why do we allow cropping?" We don't lock out cropping, because it becomes our worst nightmare if we do.  Honestly, the biggest thing we ever did in printing was to empower the consumer to set their own cropping.  They see the crop lines, they get it most of the time, and without it we had too many returns.   And the truth of the matter is, even the fussiest amongst us shouldn't worry now, because if you set your gallery to a proof delay,  you can always re-crop.

Grandpa's head is chopped off? No problem, just recrop it.  When you are done, hit the "Ship It!" button and the order goes off to our lab.
