Re: For your consideration
I know one couple who have spent getting on for $50,000 between them for camera gear - MK-II's, 300 and 600 lenses, etc. They tread all over working photogs territory and give away their work for free. Their work isn't that good (good gear - no talent), but when it is free you can imagine everyone wants it.
One danger about giving work away for free is you could be taking bread out of the mouth of people who need to earn their living from it. If you want to do something for free, just be aware of the impact on other photographers, if there is any. You could find yourself a pariah, just like those above.
