This is entirely insulting to the value of the time and skill and commitment of a photographer.
They even want to vet the quality of his work before "allowing" him to work for free.
" talk about looking a gift horse in the mouth"
They also "Require" the volunteer to be available on demand with out even paying a retainer or compensation for absence from employment.
I would also expect them to cover full insurance, or pay for its purchase.
It will be interesting to see if they get any "Takers"
However in the great scheme of things, I have no problem in doing voluntary photography, as I have done so for the local museum and the local church.
I have no problem in letting them use any photographs copyright free and for any purpose, though I retain the the Copyright myself.
As a retired professional I need to find such work "interesting" or I do not get involved. I certainly never feel "obliged" to do it.
This year I shall be volunteering to cover some major renovation work, which is taking the best part of a year to complete, for my local church, and supplying images to the Lottery fund who are paying most of the renovation costs.
