Anleitung Zusammenfassung
What does treatment with a toner solution do to a black-and-white print? • Changes or enhances the image color to convey a mood or impression, from subtle to extraordinary. • Extends the life of the print image during display or storage. Toning converts the black-and-white silver image to an inert compound, which reduces the harmful effects of intense light, ultraviolet radiation, oxidizing gases, extremes of temperature and humidity, and fumes. All Kodak toners will protect the image whether or not they produce a color shift. • Enhances the maximum density (D-max) in the image. With some toners, you can increase the shadow densities in prints with little or no change in the image tone. For example, you can treat KODAK PROFESSIONAL POLYMAX Fine-Art Paper (discontinued) in KODAK PROFESSIONAL Rapid Selenium Toner to produce a richer range of tones in the shadow areas.

ADJUSTING PRINT EXPOSURE AND DEVELOPMENT Some toners will have an effect on print density and contrast. If you know you will treat your prints with a toner before you expose and process them, you can plan ahead to allow for changes. • KODAK PROFESSIONAL Sepia Toner, KODAK PROFESSIONAL Sepia II Warm Toner, and KODAK PROFESSIONAL Brown Toner will reduce print densities. Develop prints fully, and make them slightly darker than normal. • KODAK PROFESSIONAL Rapid Selenium Toner tends to intensify the image. You may want to shorten print development time slightly. However, toning a fully developed print with this toner yields an increased tonal scale. Note: Exposure and development modifications also depend on the paper emulsion type and grade. GUIDELINES FOR PRINT PROCESSING Toning cannot disguise poor print quality. Use a properly exposed and processed print made from a high-quality negative. A good candidate for print toning should have a full tonal scale with good detail in the highlights and shadows. To obtain consistent results with toners, follow processing instructions exactly, use fresh processing solutions, and establish a consistent technique. Use standard materials and methods to control the factors that can cause toning variations. Development To obtain uniform image color, use the development temperature and time recommended in the paper instructions (unless you adjust the time for a specific toner as described under Adjusting Print Exposure and Development).
