Adorama-Variable-Grade-Black-and-White-Fiber-Base-Photo-Enlarging-Paper-5x7-100-Sheets-Glossy-Surface

Adorama VGFB Gloss is a high speed variable contrast black and white enlarging paper with a double weight fiber base. The use of color filters permits selection of required contrast from a range of grades similar to that of graded papers, with the advantage to the user of reduced paper stock. A neutral image tone and a clean white base combine to give a high quality paper equally suitable for dish processing. The paper gives a consistent image tone across the grades and exhibits good sharpness. This paper 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 have the same speed (ISO P 250) and grades 4 and 5 require approximately twice the exposure. For the filter settings, grades 0 to 4 have the same speed (ISO P 320). Grades 00 and 5 require more exposure (ISO P 250). 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 darkroom illuminated by safelights Ilford 904 or Kodak OC containing 15W bulbs or equivalent; red safelights may also be used. The safelights should be at least one metre from the paper at all times and good working practice of keeping exposure to safelight at a minimum should be adopted. Unused paper should be returned to its original packaging for storage
