This is a bit of an unusual request/question as most photographers are concerned about archival rather than impermanence.
I'm planning a conceptual installation piece and my idea is for one wall of b&w photographs to deteriorate during the installation period of 4-6 weeks to simulate fading of memories.
I've looked through my books and done some internet searches - there's a lot on what to do to make prints archival but nothing on what not to do . Does anyone know of any chemicals / processes that I can utilize to make the prints "unarchival" so that they will visibly change over 4-6 weeks?
Much appreciated for any suggestions.
