With only a couple of exceptions, all photos of mine that have appeared anywhere were digital images, either shot that way or scanned slides. By doing so, I don't need to worry about getting anything back.

All I expect is photo credit, beyond that I don't care. I have answered most requests, but one organization will NEVER,ever, no way, no how, get anything from me, digital or otherwise. When contacted several years ago by the California State Railroad Museum & Scrapyard, I responded I would burn everything before I would let them get their grubby hands on it. Why? They couldn't preserve rocks in a Mason Jar and, as a gun owner, I and everyone else with firearms has been screwed over by the State of California.
