In journalism, the “cutline” is the text below a picture, explaining what the reader is looking at. It’s what most people call a caption, but to a journalist, a “caption” is more like a title, while the “cutline” first describes what is happening in the picture, and then explains the significance of the event depicted.
Here, we see a dry, pointless cutline that offers nothing at all that the reader can’t gather from the picture. Yes, I can see the guy is gesturing. Snooze!
A much more effective cutline builds on the photo to draws the reader into the story.
