I've always been curious what it would look like if magazines had to publish the "unphotoshopped version" side-by-side with the "final version" inside the magazine. Would people check the before/after and it would lessen any negative effects? Would magazines photoshop things less?

Note: I understand there is nuance in the definition of "photoshop", with respect to processing a "raw" photo for lighting/color/etc, versus manipulating it to add/remove/blur/liquify/shape.
