I do all the school photos for the enjoyment and for the kids. Also by doing the photos I get a lot more freedom to wander about on sports days and other days when otherwise I would be stuck timing or marshalling or something where I would have to be in the same place all day.
I dont make any $ out of parents or kids.
A lot of kids ask me to email them the originals which I dont mind doing at all. Aside from that the kids love seeing photos of themselves and their friends and I can take the worst photos and they love it anyway

lots of satisfaction !
