Look at this. This is an actual photo that was taken by an SR 71 

The film inside the SR-71’s camera was five inches wide and two miles long. Once an SR-71 returned to base, the photo-maintenance division removed the film and cut it into 500-foot-long segments. 

From there, they would put on surgical gloves and go up and down the lines, inspecting this missive roll of film for cuts, tears, or scratches. This was a time-consuming process that had to be done correctly or else the entire mission may have been for nothing. 
This is the bay area of the city of Monterey in California taken from 85,000 feet from an SR 71
