EXERCISE 3:3

Working with black and white materials doesn't mean that you can't work with color in the darkroom!  Add color to your silver gelatin prints using a process called toning.  To tone a print, is to change the color of an image by chemical reaction. This color shift happens after your print is processed in the darkroom, depending on the solution, the color change can be temporary or permanent.  Images can also me toned, or stained, with organic materials.

[ PART ONE ]

For this exercise, I want to encourage you all to dry different types of paper. Trade with your classmates or buy something that you haven't tried before.  Everyone will be required to print at least 1 of their finished exercises on fiber (FB) paper, which will be provided by the Instructor.  Before you start toning, your assignment is to pick 1 negative (or equivalent) and make 6 copies total of the same image.

[ PART TWO ]

Now that you have all 6 copies of your image, you are ready to experiment with the variety of toners we have available to you.  Follow the instructions for each toner accordingly, paying special attention to the washing and drying of your print.  By the end of this exercise you should have the same image in 6 different colors - don't forget to keep 1 original!  The organic toner can be any material of your choice.

In photography, toning is a method of changing the color of black-and-white photographs. In analog photography, toning is a chemical process carried out on silver-based photographic prints. This darkroom process can not be done with a color photograph. There is debate as to whether a toned black-and-white photograph should be considered to still be black-and-white, as simply being monochromatic is not a sufficient condition for an image to count as black-and-white. The effects of these processes can be emulated with software in digital photography.

HOW DOES IT WORK?

Most toners work by replacing the metallic silver in the emulsion with a silver compound, such as silver sulfide in the case of sepia toning. The compound may be more stable than metallic silver and may also have a different color or tone. Different toning processes give different colors to the final print. In some cases, the printer may choose to tone some parts of a print more than others.  Areas of a print can be masked to stay its original color, or to tone a different color to create a duotone print.

DIFFERENT TYPES OF TONERS

LEGACY SEPIA TONER  
Legacy Pro Sepia Toner produces warm brown tones on cold-tone papers or yellowish brown tones on warm-tone papers. A two-solution bleach and redeveloper-type toner similar to Kodak Sepia Toner. Legacy Sepia Toner MSDS

BERG’S BLUE TONER  Model: 232032
Berg Brilliant Blue Toner is used, in ordinary room light, to convert black and white prints or films to a rich, deep blue color.  The toning result depends on the time of treatment and the nature of the black and white material. All silver-based black and white images may be toned; however more rapid toning occurs with warm-tone papers. Toned images are often reversible, either partially or totally, simply by redevelopment in ordinary print developer. The product has no offensive odor. Berg's Blue Toner MSDS

BERG’S COPPER TONER Model: 232042
A single bath solution used for toning black and white prints or films. The tonal range is a warming effect, a brown tone, a sepia tone or a deep metallic copper tone depending on the time of toning and the nature of the photographic materials. The toner has been specially formulated to work well with modern papers, including resin-coated and variable contrast papers. The product has no offensive odor. Toned images are reversible, either partially or totally, simply by redevelopment in ordinary print developer. Berg's Copper Toner MSDS

KODAK SELENIUM TONER Model: 1464486
Kodak Rapid Selenium Toner produces several cool chocolate-brown hues with warm-tone papers, purplish brown tones with neutral-tone papers and very little or no change with cold-tone papers. Use the 1:20 dilution for print protection. To increase shadow contrast and maximum density with a minimum tone change, use a 1:20 or 1:40 dilution. Kodak Selenium Toner MSDS

THESE TONERS WILL BE AVAILABLE TO STUDENTS DURING THE DEMONSTRATION, AND DURING OPEN LAB, UNTIL EXHAUSTED.  Students that are interested in the chemistry, and plan to tone more than 5 prints in any one solution are advised to purchase their own chemistry and storage containers. 

HEALTH & SAFETY

As most photographic chemistry is hazardous, please continue to keep you and others safe by using:

Tongs
Gloves
Apron

IT IS IMPORTANT TO UNDERSTAND THAT EACH TONING SOLUTION CONTAINS A DIFFERENT COLLECTION OF CHEMISTRY.  The combination of certain chemistries can be dangerous.  Follow all directions for the preparation and disposal of chemistry and how to properly wash your prints.

NO TONERS GO DOWN THE DRAIN, ALWAYS RETURN THEM TO THEIR BOTTLES.  If chemistry is exhausted, let the Instructor to Teaching Assistant help you with proper disposal in our hazardous waste cabinet.

DO NOT CROSS CONTAMINATE THE SOLUTIONS.  You can avoid this my using water baths when appropriate, and  handling all prints with labeled tongs.


TONING WITH ORGANIC MATERIAL

Red Wine

Soy Sauce

Food Coloring

 

Coffee

Tea

Beets

For those of us who want to “tone” a print without the use of chemicals, there are some options. The most important thing to keep in mind when toning with organic materials is that you are not increasing the archival properties of your print with their use. The chemical reactions to the silver halides embedded in photographic paper emulsions are not in play here, as the “toning” is really an overall staining of the print. Think of any time you spilled coffee, tea, or wine on your clothing or, even worse, your mother’s best white tablecloth, and you can well visualize the same effects on your print! While this staining does last for several years and keeps your home free of potentially dangerous chemicals, it will not extend protection of your print from the eventual effects of decay. If you have an important print you wish to tone, organic materials may not be the best choice.

START HERE

1. PRESOAK
Submerge the print in the PRE-SOAK tray for 1 minute.

2. PICK YOUR TONER.
Submerge the print in the TONER of your choice,  times will vary.

    SEPIA (2 part solution) Part A Bleach + 1 minute water bath + Part B
    BLUE (1 part solution) shorter soaks go blue, longer soaks also cause whites to go blue
    COPPER (1 part solution) shorter soaks blacks go reddish brown, longs soaks go maroonish red
    SELENIUM (1 part solution) short soak changes blacks, longer soaks purplish brown

3. WAITING BATH
Once your print has the desired tone of color, remove the print and place it in its LABELED WAITING BATH.  


DO NOT PLACE YOUR PRINTS IN THE STOP BATH OR FIXER.

4. WASH
    Sepia: 20 min. 
    Blue: At least 20 minutes, over washing can remove the blue.
    Copper: 20 min.
    Selenium: 30 min.

5. SQUEEGEE & DRYING SCREENS
After the wash, all toned print need to be squeegeed and placed on screens to air dry.
NO TONED PRINTS GO THROUGH THE RC OR FB DRYER!

6. HEAT PRESS
Before you submit this exercise, you will need to put them through the heat press as they won’t be flat after the toning.  Make sure you prints are completely dry before placing them in the press.
