Fig. 2. Houston-Fearless Scene Tester — used for making scene test strips for color prints. The negative material is developed in a color developer containing a nontoxic color developing agent called S-5. The negative is developed approximately 10 min, based on a gamma of 0.85 for the cyan layer of the monopack film. The film is then short-stopped, hardened, washed, bleached, washed, hypoed, washed and dried. A scene test for prints from Ansco 843 Negative is similar to a cinex, the main difference being that each frame on the strip is made from a different filter balance, but each frame receives the same printing light intensity. This necessitates three tests being made on each scene, generally three printer points apart, in order to give a density range. The scene tests are developed in a positive developer similar to the negative developer, except that it does not have an accelerator in the solution. The negative is timed from the scene tests. Separate filters are made up for scene-to-scene color correction and a modified Bell & Howell printer with an automatic filter changer handles the filter combinations (Fig. 3). This filter change is made in conjunction with the notch used for the printer light changes. The positive stock used is Ansco Type 848 and is developed to a gamma of 2.30 on the red record, being the cyan layer. The sound is printed from a blackand-white negative track.
