FOMATONE MG Classic B&W Variable-Contrast Photographic Paper (42.5 x 33', Roll Sheets, Chamois) from Foma is a fiber based, warm tone paper. Featuring a cream tone this Chamois paper is both subdued in color and heavily-textured, much like watercolor paper. Fine art photographic prints, handcoloring, and other alternative processes do well with this paper.
Aside from being a heavier weight paper with a pleasant tone, the MG Classic Chamois Paper features the same contrast latitude as the others in the FOMATONE line. Contrast varies from 0 to 5, providing flexibility when printing. When it comes to storage, it is recommended that FOMATONE is kept in a cool 68°, in a dry place, in the original light-tight packaging. This ensures that the paper will keep its maximum validity throughout its lifetime, for rich, engaging prints.
- In General
- FOMATONE MG is a variable-contrast photographic paper working in a warm tone, specially designed for portrait photography and retro style works. Its contrast can be varied in a large extent from extra soft up to ultra hard by using color filters at exposure. The paper is manufactured using a special silver chlorobromide emulsion that gives the silver image a brown-green to warm-brown tone that can further be influenced by the type of developer used. The paper base involved is colored in compliance with the tone of the developed silver. This accentuates rich scale of warm half tones ranging from light cream up to saturated brown-to-green black ones. Regarding its low speed, the paper is designed primarily for contact work, it can be, however, used as an enlargement paper as well
- When working with FOMATONE MG, the same safelighting can be used as with other common black-and-white photographic papers, i. e. yellow-green, orange and red safelighting with filters (e.g. Ilford 902, Osram Duka 50, Durst Sanat, Agfa G7,Agfa YJ7 etc.)
FOMATONE MG can be exposed in all types of enlargers and printers equipped with tungsten or tungsten halogen lamps. Particularly suitable are devices with a special color mixing heads for multi-contrast papers. Other enlargers can also be used, but separate correction filters should be inserted during exposure.
During enlarging, a fact has to be taken into account that the speed of this paper is considerably lower than that of other Foma photographic papers so exposure times have to be adequately longer
- Contrast Control
The contrast can be continuously varied from extra soft (contrast grade 0) to ultra hard (contrast grade 5). FOMATONE MG being sensitized in blue and green spectral areas, its contrast is controlled using yellow and magenta filters during exposure. If only the blue sensitized part of the emulsion is exposed (under magentafilters), the contrast will increase; if the green sensitized part of the emulsion is exposed (under yellow filters), the contrast will reduce. If no color filtration is used, the contrast grade of the paper equals 2 (special).The following methods and devices are recommended for the contrast control:
- Standard sets of filters for variable-contrast papers (e.g. Foma Variant Filters, Ilford Multigrade Filters, etc)
- Magenta and yellow filters in color mixing heads
- Special enlarging heads for variable-contrast papers
- Color printing filters (yellow and magenta)
- Color printers with a program for variable-contrast papers
- Black & White printers with an inserted magenta filter for hard and ultra hard contrast grades
- FOMATONE MG can be toned using the Fomatone Sepia two-bath toner by which a yellow-brown image tone can be obtained. In this case the temperature of the toning bath is not as relevant as with Fomaspeed-type photo papers. The prints should be mildly overexposed for toning. A blue tone can be obtained using the Fomatoner Indigo Set. The resulting image tone depends on dilution, temperature, and toning time
- FOMATONE MG should be stored in intact original packaging in a dry, cold place (temperatures of up to 68°F and relative humidities ranging from 50 to 60%), out of reach of harmful vapors, gases, and ionizing radiation
- FOMATONE MG can be processed both manually in trays and automatically in roller developing machines. The processing procedure does not differ substantially from that of other Foma photo papers. Any common developers are suitable but FomatolLQN, Fomatol P, and Fomatol PW developers are particularly recommended for their brown-green and warm-brown image tone respectively; the last developer having specially been formulated for this paper. In general it is necessary to take into consideration that any developers giving more expressed images usually reduce contrast and the yield of speed. To obtain warmer tones of developed silver, shorter development times are recommended (up to an optimum of 3 minutes, depending on the type of developer used). Stopping the development before fixing is very important with this paper - any neglecting the procedure recommended can cause non-homogenities of gray areas on prints. To accentuate the resulting image tone, special developers of foreign manufacturers designed for warm image tones are recommended, e.g. Agfa Neutol W A, Tetenal Neutral type Liquid and the like
