For concert performances like dance groups, I'm just figuring out a way to make purchasing of photographs appealing.
Where a concert is made up of different dance troupes (keeping in mind group and single portrait photos are already covered, I'm just doing "performance photos"), how to make an offer attractive.
The reason for this is that I have been told that a few years ago, another photographer was hired to do the performance photos only, but then none of the groups purchased any. Now the troupes organising the event have asked for performance photos again, I'm working out a system for ordering or purchasing at the event rather than afterwards and risk having none sell.
I'm taking into consideration that more people have websites, facebook groups, advertisements etc for their groups, there may be a small demand there for the photos now - in fact some groups do have professional performance photos already so some do use them.
Two options I've thought of are to firstly request a small "hire" fee from the event organisers (that way I get something at least for my time and effort). Secondly, ask that groups pre-purchase their set of photos on the night instead of being approached by individuals (this would be hard to guarantee photos of that one individual performing due to the scale of the event) and after the event. By having the whole group purchase one set of photos up front, would it be reasonable to allow them to copy & distribute images within their particular group (it's not really preventable anyway?).
