Two motion-picture cameras were aboard Apollo{{nbs}}4. These were mounted on the Saturn{{nbs}}V so as to capture the separation of the first stage and interstage from the launch vehicle. They would then be ejected, descend to the Atlantic Ocean in pods with parachutes and radio beacons, and be recovered about {{convert|470|nmi|km|order=flip|sp=us}} downrange of KSC.{{sfn|Press Kit|p=12}}

The command module contained an automatic [[Medium format (film)|70{{nbs}}mm film]] camera which captured photographs of almost the entire Earth. For a period of two hours and thirteen minutes as the craft approached and passed its [[apogee]], a total of 755 color images were taken through the Command Pilot's (left-hand) forward-looking window, at altitudes ranging from {{convert|7295|to|9769|nmi|km|sp=us|order=flip}}. These were the color images taken from the highest altitude at that time. The photographs were not of sufficient resolution to obtain detailed scientific data, but were still of interest to those involved in the [[Earth sciences]].<ref name="photoAnal">{{cite book |last=Dornbach |first=John E. |title=Analysis of Apollo AS-501 Mission Earth Photography |url=http://apollo.sese.asu.edu/SUPPORT_DATA/ap04_index.pdf |access-date=July 8, 2013 |date=February 1968 |publisher=[[Lyndon B.
