RE: haunted VDB
The silver image of VDB is said to be quite vulnerable to attack (by say pollution in the air), since the silver filaments of VDB (if they have that shape) are quite small, in general the smaller the silver filaments, the warmer/browner the image, and toning with gold protects these silver filaments..but also changes colour (for the better IMHO...) Did the white parts of the image change colour (towards yellow) because that would indicate that you did not fix strong enough, change of colour of the blacks could indicate that you did not wash the fixer out enough (I used also a hypo-clear step) ...but I should stop, my experience with VDB is limited and dated, Best, Cor -----Original Message----- From: Joao Ribeiro Globo [mailto:ribeiro.joao@globo.com] Sent: woensdag 30 september 2009 14:56 To: alt-photo-process-l@usask.ca Subject: Re: haunted VDB Hi Cor, No treatment other than normal processing and washing.
