A caption turns a photo into something that explains itself, which matters when it is going into a group chat or a listing without you there to describe it.
White text on a photo disappears the moment it crosses something pale. An outline in the opposite colour keeps it legible no matter what is behind it, which is why memes have always been set that way.
Keep captions short. Text across a picture is read at a glance, and anything longer than a few words will be skipped.
The caption is drawn at the photo's full resolution, so it stays sharp when the picture is viewed large or printed.
Captions sit top and bottom. For text anywhere on the picture, the watermark tool places a mark in nine positions.
