I've just printed a neg that seems to be printing with too much contrast as a Van Dyke..is there any stategy for lowering the contrast of my VDB coating for this particular neg. I double coated a sheet of Crane Platinotype and used a VDB traditional mix..

You can try:

Different light source
less exposure
more exposure
longer/stronger fix
single-coating
diluting the mix
additional tartaric acid
a hint (note: hint!) of oxalic acid
different paper

All - or none - of these may work.

Wow, if it is too contrasty for VanDyke, the negative must be armor plated!

If you are really stymied, try reducing the contrast on your negative with the two-step farmer's reducer, which will remove more silver from your highlights than your shadows, causing a lowering of contrast. This trick has saved my bacon occasionally.

Get the recipe from Ed Buffaloe's unblinkingeye.com site. Soak your negative for about five minutes, then transfer to the ferricyanide bleach bath, and keep an eye on it.(probably no more than 3-5 minutes) Transfer back to a running water tray and rinse the bleach off of the negative and then put it in the hypo tray and fix and wash.

I would not try this unless you have some decent shadow density on your negative to begin with, since the shadows will be affected, but not nearly as much as the highlights. A one step Farmer's reducer will hit the shadows first, and is useful for reducing an overexposed negative. Since the process is irreversible, but repeatable, I would recommend doing the bleaching step in 2-3 minute chunks until you get your negative into line.

Of course, almost all my negatives are perfectly exposed and processed, so I guess I should make clear that I have used this trick for the benefit of my evil twin, who occasionally gets sloppy.
