1. THE USE OF FILM TYPE 2475 (ROYAL X PAN) FIR NIGHT
PHOTURAPHY EXPERIMENTS ON MISSION 4029 PRODUCED ONLY A RECORD
OF LI$HT SOURCE PATTERNS. NO IMAGERY ILLUMINATED BY REFLECTED
LIGHT WAS RECORDED. THE LIGHTS WHICH DID RECORD WERE SLIGHTLY
BREARED BECAUSE OF AN INTENTIONAL IMC ERROR. THIS SMEARING
1966
TECXNIOUE AFFORDED ADDITIONAL EXPOSURE THROUGH THE USE OF A 1 8 JU---- L.

SLOWER FILM VELOCITY AND PROVIDED THE INTERPRETER WITH A MORE li yy Office
POSITIVE MEANS OF IDENTIFYING GROUND LIGHTS FROM FILM DEFECTS,
DIRT, DUST, ETC.
2, IT IS OUR CONCLUSION THAT FOR GENERAL USE, NIGHT
COVERAGE OF THE QUALITY PRODUCED BY THIS MISSION, IS OF LITTLE

TO SERVE AS ABASE, THE LIGHT PATTERNS RECORDED ON THIS MISSION
COULD NOT BE EIS1 TO DETERMINE THE LEVEL OF ACTIVITY AT ANY
TARGET. WITH SUFFICIENT BASE INFORMATION AVAILABLE, THE
ACTIVITY LEVEL WOULD STILL BE ONLY A CONJECTURE DRAWN FROM THE
NUMBER OF LIGHTS WHICH ARE RECORDED RATHER THAN FROM GROUND
SCENE IMAGERY DISPLAYING A DEFINITE ACTIVITY LEVEL. UTILIZATION
OF HIGHER SENSITIVITY FILMS CAPABLE OF RECORDING SCENES LIGHTED
BY "MOON LIGHT," WOULD GREATLY INCREASE THE INFORMATION AVAIL-
ABLE ON NIGHT COVERAGE AND PROVIDE SCENE IMAGERY RATHER THAN
JUST LIGHT PATTERNS.
5. IT IS FELT THAT THE R&D EFFORT SHOULD BE CONTINUED
IN THE REGION OF NIGHT AND "MOON LIGHT" PHOTOGRAPHY. AT THE
PRESENT TIME, HOWEVER, SHOULD A SPECIFIC REQUEST ARISE
REQUIRING THE POSSIBLE USE OF OPERATIONAL NIGHT COVERAGE,
SHOULD BE CONTACTED SO THAT WE MIGHT DETERMINE THE
CAPABILITY OF SUCH PHOTOGRAPHY TO SOLVE THE PROBLEM AND ALSO
DETERMINE THE TYPE AND EXTENT OF SUPPORT INFORMATION WHICH
WILL BE REQUIRED FOR THE FULLEST PHOTOGRAPHIC INTERPRETATION.
6. FOR FUTURE R)D EXPERIMENTS, A RECOMMENDATION FOR
NIGHT PHOTOGRAPHY OVER A SPECIFIC TARGET HAS BEEN MADE BY
PHOTOGRAPHIC INTERPRETERS AT AND IS AVAILABLE UPON
YOUR REQUEST.
