Prints of old negs that have been treated with chlorine to achieve a faded look, then cropped to a very small square size and binded in a book. Only one copy of this book was made, of course.
Thanks, David ! There's no mystery about the chlorine... I just used some diluted chlorine bleach on the prints, after I accidentally discovered that it quickly dissolves the emulsion. This is how it worked for me: I placed the print in a tray, then sprayed some diluted Clorox on it using a spray bottle (like the one we use for spraying the plants) and when the image started disappearing, I stopped the process using running water from a hose. Some images were "saved" at the right moment and some had to be thrown away because I wasn't quick enough and the image was completely gone. It was mostly a matter of luck, if the final result was going to be successful or not... luckily, there was enough material (prints) to play with and finally I ended up with a number of photographs that looked OK... in the end, I cropped most of the print out in order to keep the most interesting part and discard the areas where the marks that the bleach left were too disturbing. This left me with some nice but too small for wall display prints, so I thought that the best to do with them was to make a book. I contacted the brother of a friend who is a book binder, he accepted the task and a few weeks later I had the book in my hands.
