>>2985526In addition to having only one photo for person, I would suggest omitting names entirely. Just include a note somewhere in the book that each photo is by a different photographer. I don't think it would upset anyone (in fact, it would remove the opportunity for someone to be mislabelled) and it would streamline the design.
Creative layouts can make sense for a collection of one photographer's work, but in our case I believe the book should be square with one photo per page, centred and taking up most of the page in the long dimension. That will show off the photos best and be equally fair to everyone. It also makes the process of putting the book together a lot faster.
>>2985616I don't think this is a very good idea for a book being done just once a year. There are other avenues for collecting photos from /p/ that fit a theme.
Each person submits up to three photos and a small team of curators selects the best one. I think that would be the optimal way to do it.
