Experiment M410: Color patch photography
A slate that supported four calibrated color targets was photographed during Gemini 10 mission extravehicular activity to determine if existing outdoor-type color films can reproduce colored objects accurately in the space environment. The experiment resulted in the acquisition of sufficient information to confirm that objects can be photographed in space with good color fidelity by the use of existing materials. Available color film is balanced to the solar spectrum in space, and the effect of ultraviolet energy on film degradation appears to be negligible.
