Printing papers warm-tone

This information can be quite useful. For example, giving a print more than the usual exposure and developing it for less than the normal time, say 45 seconds to 1 minute, will often enhance warm tones, especially with chlorobromide papers. Using a warm-tone chlorobromide paper and developer combination will further heighten this effect. With bromide papers the results may be less than satisfactory as the color may be muddy olive depending on the paper. 

Another combination is to use any sepia or polysulfide toner, then Kodak T-26 Blue Toner. To use this combination, wash the print thoroughly after using sepia or polysulfide toner then use T-26 as per directions. The red tone should appear after approximately 15 to 30 minutes in this solution at 90F/32C. This technique usually produces a density loss in the shadows. Start with a print that has higher-than-normal contrast. Cold-tone papers will produce a truer red warm-tone papers will produce an orange hue. 

Excessive fixing times will promote adsorption or retention of the fixer complexes in gelatin, or more particularly on the fibers of paper base, and should be avoided. In addition, excessive fixing can bleach silver images, especially those on paper prints. Warm-tone images are particularly at risk. 

Changes and variations in image tone may not always be as glaringly apparent. Often the difference is subtle, so much so that someone viewing a print might not even be aware that it is neutral, cool, or warm, unless the fact is drawn to their attention, or they see an example of each, side-by-side. The simplest test to determine whether or not a paper is cold-, warm-, or neutral-toned, is to develop it for two minutes in a neutral tone developer such as D-72 and compare it to other papers developed similarly. If a paper is warm- or cold-toned the color can be seen in the shadows. 

Many substances will color prints. In fact, a beautiful and permanent warm tint can be achieved on many papers by using your morning coffee. 1 After fixing and a brief rinse in running water, immerse the print in cold or warm coffee until the desired brown tone is reached. Finish by washing the print in the usual manner.
