Each scan is costing me around $750-$900?
I applaud your efforts and think what you do is amazing. That’s a very expensive hobby.
Does buying that film gain you copyright owner status? Does it give you the right to share digital copies that you’ve restored?
I get that it’s expensive and time consuming, and I think it’s pretty great.
However, you’re still buying and sharing without permission the copyright works of others. I support you in your efforts, but I’m not going to lie to myself and others that its somehow not still piracy.
