external New Models are Changing the Way Photographers Publish Books —American Photo

“The publisher takes on the financial burden, and it goes out into the world, and if it sells 250 copies or it sells 2,000 copies, the photographer has got their 50 copies and they see the book in print [...] In our model, there’s a possibility that the book is not even going to happen. That’s scary for all of us. But the truth is, we have more books today than we have audiences to buy them—and so that’s pushing people to try things in new and different ways.”

hacking“Back in the days, when we were still capturing images on sheets of plastic, ISO (also known as ASA) was not a button on the back of a camera. It was a chemical property of the film. Some cameras could read the encoding on the film can and set the ISO accordingly. But sometimes you wanted to get more out of a film – to set it to a higher (or lower) ISO. This process is called pushing/puling the film, and if the camera you had could only do auto ISO decoding, you had to hack the film.”

Each image triggers associated recollections, and they roll alongside, hovering around each picture.
