Selective Toning
Toning selective areas involves using a liquid or plastic frisket material to cover the parts of the image that you don't want to tone. For best results with this technique, choose scenes that have a distinct line between the areas that you want to treat differently.
You can apply a liquid frisket material, such as Photo Maskoid Frisket or Dr. Ph. Martin's Frisket Mask Liquid, with a brush. These materials are available from art-supply stores.
You can also use sheets of clear self-adhesive frisket material, such as Transpaseal or Grafix Frisket Film, sold for airbrush work. These materials are available from art-supply stores. After applying the sheet of frisket material to the print, use a frisket knife or an X-Acto blade to cut carefully around the areas you want to tone. Peel off the unwanted frisket material by picking up a corner with tweezers.
After you have applied the frisket material, follow these steps:
1. Soak the print in water (fiber-base for 10 minutes, resin-coated for 2 minutes).
2. Place the print in the toning solution. Let the toner flow freely over the uncoated portions of the print. Don't worry if the print buckles or curls during toning.
Note: If possible, keep the part of the print you don't want toned out of the solution in case the toner bleeds under the frisket. If you can't do this and the toner tends to bleed, try skipping the presoak step.
3. Wash the print as recommended in the instructions for the toner you're using.
4. Remove the frisket material. You can usually remove liquid frisket materials by rubbing your fingers gently over the print while it is still in the wash. Remove Photo Maskoid frisket by touching sticky tape to an edge.
When you use two or more toners sequentially, follow the same procedure for each toner.
