As more and more photography books are published, more and more photographers find themselves in a position many literary authors know all too well: behind a table, pen in hand, signing their books. Oddly enough, many of the people attending these events seem completely unaware of the etiquette that has grown up around book signings. The new photography book enthusiast apparently thinks nothing of engaging the photographer in long, technical discussions and/or highly detailed questions about specific works, a discussion they seek to continue even as those in the line behind them present their books to be signed. They don't bother to open the book to the title page and present it thus to the photographer, instead creating an extra moment or two of work for the photographer. And they seem to delight in asking for tediously detailed personal inscriptions, which drag the process out even further.
The informal rules of a photography book signing are simple:
1. Have the book open and ready to sign. Pay attention to the person in front of you: if the photographer signs on a particular page, have the book open to it.
2. A brief comment or two is certainly permissable, but starting a Q&A isn't. There are people behind you, and even the most stalwart photographer quickly grows fatigued. At some events hundreds of people line up, and everybody wants the same thing.
3. Personalized inscriptions at lightly attended events are fine. In a crowd, however, they're not. Wait until the end of the event and see if you can be accommodated, or settle for the usual "To [your name here], best wishes."
4. Do not hang around the signing area and attempt to engage the photographer in conversation as he or she signs other people's books. That is hugely annoying to everyone.
5. Some photographers will sign just about anything that's put in front of them, such as postcards, reproductions, posters and the like. Many others, however, won't.
These conventions are more or less ingrained in literary book signings. They're applicable to photography book signings too.
