Captions are everywhere. And so many of them could do with more thought.
For example, I saw this on Twitter:
The fundamental thing about a caption is that it goes together with a picture! So the caption only needs to contain details that the reader cannot see, or infer. No need then to say that so-and-so laughs as she meets her friends. If she is visibly laughing, the picture is doing its job. In the case of the camel, the offending word is “seen”. It’s just not needed. My suggestion for a better caption (and note – you don’t need to repeat Dubai):
A camel is readied for foot surgery at the Dubai Camel Hospital.
