Probably the next step is laser disc, and I may live to see the end of film and darkroom type printing. The automatic printing on the one hour machines will seem like the mechanical typewriter in the computer age. I did some soul searching when it came to choose photos for this book. Some are so dark, poorly preserved or poorly copied that I finally gave up on them ever being anything. Where that is the only photo of someone, I weakened, but decided you can't use them all.
Cost is one limitation, time another, and just plain laziness has a place somewhere in there too.
I wanted to make it easy, so looked into Xerox printing as a way to go. There are techniques that work, making the pictures about as good as newspaper pictures, but cost plenty. Where thousands of copies are to be made, the number of cheap copies balances the setup cost, but my production runs are going to be small. I chose double sided tape tabs.
