Cinematographer [[Joseph A. Valentine]] described his work on the film: "Our Santa Rosa location was chosen because it seemed to be typical of the average American small city, and offered, as well, the physical facilities the script demanded. There was a public square, around which much of the city's life resolves. There was an indefinable blending of small town and city, and of old and new, which made the town a much more typical background of an average American town than anything that could have been deliberately designed. The Santa Rosans were very cooperative, and most of our problems in these scenes were the ordinary ones of rigging scrims and placing reflectors or booster lights where they were needed."

"The most spectacular part of our work was naturally the making of the night exterior sequences. We had with us two generator sets, ten 150-ampere arc spotlights, and the usual assortment of incandescent lights...making a total of 3,000 ampere maximum electrical capacity. With this we lit up an expanse of four city blocks for our night-effect long shots!....Oddly enough, one of our less spectacular night scenes proved really the harder problem. This was a sequence played around the city's public library. This building is a lovely Gothic structure, almost completely clothed in ivy. I think all of us were surprised at the way those dark green ivy leaves drank up the light. Actually, on our long shots of that single building we used every unit of lighting equipment we had with us—and we could very conveniently have used more if we had had them!....Frequently people who have seen these night scenes of ours have jumped to the conclusion that with such an area to illuminate we must have filmed them by day with Infra-Red film rather than actually by night. If only they'd seen how we worked to finish our night scenes before the Pacific Coast's "dim-out" order [of WWII] went into effect, they'd change their minds. All of our night scenes were filmed actually at night—and we just got under the wire, finishing the last one scarcely a matter of hours before the dim-out became effective."<ref>Valentine, Joseph A.
