This imbalance is the issue. The photographer attempted to use a fraudulent system designed for the wealthy. Hopefully the loss disillusions those among us hoping for scraps. As an amateur photographer, post all you want, and expect nothing in return. If you shoot digital, keep your raw files to harvest lower-fidelty, online-ready formats. If you shoot film, you have both the scans and the negatives.
