Are the images crooked, or keystoned? Are they supposed to be the final images or just samples out of the camera and his customers get the edited files/prints after selecting the ones they like?
Bambi Cantrell claims she edits everything before a customer sees anything. Jeff Cable edits a few, shows the customer everything worth looking at and edits the ones the customer picks. His view is time is money and since he has a day job, he doesn’t have time for unnecessary editing.
If I recall, Cantrell also gives away a disk. Her view is she billed them enough to cover it so if they print elsewhere, oh well. Cable sells prints. I think you can get a disk suitable for Facebook.
If he outsourced post, and the keystoned photos on his page have been through post, he needs a new retoucher.
