Check a Photographed Proof

Reading starts as soon as you choose a picture. Need a blank sheet? Print the proof template — proofs written on it are read more reliably than proofs on plain paper.

What happens next

The photograph is read, and the transcription appears beside it for you to check and correct. Only then is the proof checked — so a misreading costs you an edit, not a wrong answer. Pay particular attention to the Depends column: a blank cell there is meaningful, and it is the column most often got wrong.
