Volunteer work is admirable but almost impossible to get around here. After 40 years of experience in city/town planning, civil engineering, architecture and teaching at Georgia Tech for years, I have been completely unable to obtain volunteer work of any kind. THAT is what makes one sour, not doing what one likes to do or has the talent to do.
Before the recession, I did a lot of volunteer work for ministries, churches and such and NOT one time did those people understand what it took to do professional work and since they did not pay for it, they never appreciated it. None of that work was photography. Now that I am a full-time photographer, I work for myself. If it sells, great. If it doesn't, no problem, but I will not give away my professional work or services. Even if I charge just $5, it is the message I am sending and that is just the way I do business.
Personal photography? Yeah, I give away a print here and there, mostly to family or someone who is genuine IMO and they are the folks who appreciate it. Just recently gave a couple of 5x7 portraits to an elderly historian and a cool guy on dialysis, oxygen and a heart patient in a wheelchair. Those are the people deserving of a lot more than I can give them.:angel:
Do what you want. If it makes you happy, then that is good. If you can make others happy, that is even better. If I can pay the bills, then everybody is happy.
