Why protected galleries sell
When the proof can't be screenshotted, the download is worth buying.
A sales gallery only works if the previews aren't already good enough to keep. With most galleries, clients screenshot the proofs and the order never comes.
ProofProtect previews are full-screen and sharp for the viewer, but screenshots and screen recordings come back black and every image carries the viewer's email. The only clean copy is the one they pay for.
