I discovered a shop that sells a package of 3x24exp. color C-41 films for just 2,99 euro, that is to say, 1 euro per roll. It was so cheap that I decided to give it a try. I was realy surprised with the quality. These films are produced in Japan for Anton Schlecker in Germany. They expire in July 2014, which means they are still valid. The next, I am buying a complete stock for years, if I find them again.
I exposed the film with a Konica point and shoot camera, Z-up 80 and developed using Dignan's 2-bath C-41 process. The film was scanned with an Epson V500 and treated with the free software Photoscape.
