A daylight loading film developing tank is shown, specifically adapted to permit sequential loading and a simultaneous developing of multiple reels of film under non-darkroom conditions. The tank has a removable upper film loading chamber containing a removable dark slide which permits the light-tight isolation of a developing tank chamber inner portion from the reel loading and film inserting portion of the daylight loader top. A separate, fully baffled, chemically passing developing tank cap is provided. A coordinated series of mating threads within the film loader top, the developing tank top, and the developing tank permit the chemical passing baffled tank top to be inserted into the developing tank through the interior of the film loading chamber of the daylight loading top. The daylight loading top portion can then be removed, converting the tank to a standard light-tight film developing tank suitable for sequential chemical processing. The overall system permits, without the use of a darkroom, a number of individual rolls of film to be sequentially loaded onto reels; these reels are then removed to a multi-reel film developing tank. The invention has a developing tank which can be enlarged by adding sections to it, permitting the invention to be used with any of a number of desired quantities of film reels.
