The same prices as for photos taken in social events apply but, if you don't take the "Credit removal" option and once I got the entrance price back I'll keep only 2 EUR per photo and the options price, the rest of the base price will go to the event, or next year's event if not possible otherwise.
Which, at current rates, makes approximately 6 EUR/photo for the event, and 2 EUR+options/photo for me.
If you take the "Credit removal" option, I'll give only one Euro per photo. (That's because I'm not fan of credit removal, even paid.)
