Efke 11 x 14" Black and White Print Film has a high silver content and an orthochromatic emulsion. This polyester film is quite flexible in the darkroom. Varying the concentration of your developer can alter the ISO rating and also tweak the contrast. Originally produced to replace Agfa's Gevatone N31P, this warm chlorobromide based film is easily toned with items such as Cachet/MACO Sepia, Selenia and Azure Blue toners.
Note: Replaces Maco Genius Print Film; use a red filter during processing. Be sure the distance from tray to safelight is at least 40"
A fast emulsion - best to use a step wedge to determine proper exposure
Orthochromatic emulsion coated on a clear 170 micron polyester base
Efke Print film tones in all available toners: Cachet/MACO Sepia, Selenia and Azure Blue toners. With the blue toner, underexpose by 0.5-1.0 stops because blue toners add image density
