I started working on a Blurb book just to have something to put out there for my climbing friends. But, in the process I have come across the perennial question: what is this book about? It was just a book of pretty photos but now I am debating whether I should broaden the audience. SImple questions like - should I put captions? I don't remember everyone's name though. But, each photo does have a story. I am concerned that in putting captions I will be making a radio edit (and then he walked through the door) which would be largely redundant if the photo does its job.
