RE: haunted VDB
Are the prints also fading along with changing color? If they're also fading I'd suspect the porfolio and/or a mistake in processing. Have you cleared and washed well the prints? Do you notice a yellow stain (most notably when looking under a bluish fluorescent light? See my procedure below: 1. Wash 2 mins in 2 separate baths of dilute citric acid (a dessert spoon to 2000ml water) 2. Gold tone (optional) 3. Fix for 2 mins. in 2% plain sodium thiosulfate 4. Wash for 15 minutes chaning water at least 5 times. No problems with untoned (yet!) and toned prints as old as 6 years so far... -----Original Message----- From: Joao Ribeiro Globo [mailto:ribeiro.joao@globo.com] Sent: Wednesday, September 30, 2009 3:56 PM To: alt-photo-process-l@usask.ca Subject: Re: haunted VDB Hi Cor, No treatment other than normal processing and washing.
