I think we’ve all “lost” an image at one point in time. If you haven’t had it happen to you, then you’re not lucky, it’s just hasn’t happened to you yet.
Your still camera has issues, or there’s a bad import session between your computer and your still camera and suddenly, your images are gone. Or one of your kids, or someone playing a joke on you deletes an image you wanted to keep on your camera.
Well, there’s an easy solution…
(how seldom do we really get to hear that!)
