Tests were conducted to evaluate Kodak MX-857 and MX-641 chemistry systems for use with film Type 2485 to be used in the dim light experiments on Apollo 16. The test program objectives were to: (1) retain a minimum ASA speed of at least 4000; (2) maintain a base-plus-fog level of 0.21 density units or less; and (3) minimize the granularity but do not exceed the granularity level of the Apollo 15 imagery. Test results on the Versamat processor indicate that the use of MX-857 chemistry is preferred over MX-641 chemistry in satisfying the stated test objectives.
