Re: haunted VDB

Thanks Francis, I'll try.

Would you try this experiment. Store one VDB processed your current working method in the plastic and one processed the same way out of the plastic and compare them in three weeks time? I suspect it is the plastic causing the color shift.

Years ago I was working with a very transitive medium, fax paper, and plastic photo album pages caused extreme fading. Images stored in a plain box were unchanged.

I don't change the water during development. Should I?

Forgot to add this between 1 and 2:
- Wash in plain water for further 4-5 minutes, chaning water at least 4

BTW, I was chaning fixer every 3 prints since it was very diluted...

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...

Hi Cor,

No treatment other than normal processing and washing.

Did you gold tone them?

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,
