Adorama VGRC is a high speed, variable contrast, black and white enlarging paper with a medium weight, polyethylene coated base. The paper base is 190 g/m2 coated on both sides with 40 g/m2 of polyethylene giving a base weight of approximately 270 g/m2 and a thickness of approximately 245 microns. The silver halide emulsion has a silver content of approximately 1.5 g/m2. Adorama VCRC gives a consistent image tone across all grades, exhibits excellent image sharpness and is available in Glossy & Pearl surfaces. The use of yellow and magenta colored filters permits selection of required contrast from a range of grades similar to that of graded papers. A neutral-cool image tone and clean white base combine to give a high quality paper equally suitable for tray or machine processing. Adorama VGRC is designed for use with tungsten or tungsten halogen light sources, other light sources may give different contrast values. Exposure of the paper is straight forward, depending on which filter system is in use. For Ilford Multigrade filters, grades 00 to 3.5 have the same speed (ISO P250) and grades 4 and 5 require approximately twice the exposure. For the filter settings of table B, grades 0 to 4 have the same speed (ISO P320). Grades 00 and 5 require more exposure (ISO P250). When no filter is used, the paper has a contrast of approximately grade 2 and a speed of ISO P 640. Open only in a photographic darkroom illuminated by standard OC or red safelights con
