The Stearman Press SP-810 8x10 Daylight Processing Tray allows the photographer to bring large format sheet development out of the darkroom. The tray is easily loaded in a dark bag or dark room (no film holders needed!), and, when the lid is secured, the tray can be brought out into the light to be processed while reading a newspaper or looking at another image on a light table. With included dividers and tabs, the processor can be configured for 4x5, 4x10, and 5x7, too. The SP-810 is very economical, as it uses only 500mL of chemicals. Unit is supplied with Hold-Down Tabs that keep the film from floating out of the chemicals. Users rock/tilt for agitation. The tray bottom is designed with 4 separate fingertip indents for easy removal, when processing is complete. Pre-wetting your film in the tray is required, as it will flatten your film to prepare for proper processing.
