I feel your pain. I was 'recruited' by the local adoption group that I work with to do Santa photos this past season. I agreed to do it because I have not been as active in the group lately as I had been in the past. For me, it assuaged my guilt for not helping out more but I couldn't imagine working directly for the pet store and not getting paid a fair wage. $75 for 8 hours of shooting plus set up/take down time is barely minimum wage, never mind the mileage you are putting on your equipment taking all those shots. I think your response plan for Easter photos was more than fair and agree with the others that whatever publicity you may have gained was not worth the effort. Put it this way - if you add up your time, equipment costs, gas, etc. and used the money that you spent doing this fundraiser for actual advertising which do you think would be a better investment?
