Slow Speed (ISO 10) Orthochromatic Film. Maximum contrast for masks or special effects in Camera or Enlarger. Red Safelight OK. Can be processed in standard B&W paper developer or A&B developer for higher contrast. Used by many photographers for use in creating highlight masks for fine art printing and for creating enlarged negatives, in a two-step process, for contact printing and alternative processes. Extremely high contrast, orthochromatic (NOT panchromatic) film originally designed primarily for making line and halftone negatives for photomechanical reproduction and can be utilized as a continuous tone film, dependent upon handling, development, etc...
Wide exposure and development latitude. Produces sharp halftone dots suitable for dot etching. Can be used in professional applications for copying line originals, for producing negative slides from line copy (e.g., title slides), and for special effects photography. Can also be used for making highlight masks to improve the reproduction of important highlight detail when making duplicates from transparencies or color prints by the dye transfer process.
Continuous tone applications ISO/ASA 8-10 for general halftone works (process in an A&B type developer) ISO/ASA 10-25 when shooting continuous tone (process in any standard paper developer) Works with many different normal B&W developers and even homebrew developers such as Caffenol. These are some real basic guidelines. The film inherently has wide latitude in high contrast applications, and a much narrower window when utilizing as a mid-tone film.
Safelight Recommendations: Use a KODAK 1A Safelight Type Filter/light red or the equivalent, in a suitable safelight lamp equipped with a 15-watt bulb. Keep the film at least 4 feet (1.2 meters) from the safelight. Avoid prolonged exposure to safelight illumination. When processing you can use a Kodak 1A Safelight to check development. (Do NOT use an amber or OC safelight)
