Re: haunted VDB
The withe parts didn't change color.
Not all images changed, just a few.
Can it be paper contamination?
Thanks,
Joao

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,

Hi Cor,
No treatment other than normal processing and washing.

Hi Folks
After printing really brown prints with traditional formula on arches
aquarelle and archiving them in a portfolio, some prints changed from
brown to gray.
They were perfect 20 days before.
Does anyone know what might be happening?
Thanks in advance,
Joao
