I volunteer teaching photography, doing Christmas Photos and helpping on photo shoots with local Veterans Admin Hospitals. If you have older cameras in great condition that you can't get much for on trade or trying to sell consider donating them to local VA Hospitals (or schools and art programs). The donations are tax deductible and probally worth more on your return than you could expect to get for selling them.
Each Christmas I take photos of the vets for them to send to their families, which is surprisingly a need. Most VA Hospitals are very co=operative in helpping to arrange this if anyone else is interested. last Christmas 2 friends and I helpped 500 of those that stood for us.
No matter how slow the film, Spirit always stands still long enough for the photographer It has chosen.
