The Naughty Shutter (1963)

A big city reporter named Dick travels to a small Texas town 200 miles from his home to get a first hand look at the nudie cutie life when he stumbles upon a magical camera that takes photos of persons without their clothes. In the local hotel, the reporter tries to purchase the camera from the owner, only to loose the camera in which it gets stolen and ends up in the hands of various people, a businessman, a maid, and an undertaker who uses it to take pictures of a trio of nudest women in the room down the hall from his. Soon everyone is looking for the camera including the hotel manager, a spy wanting to sell it, and a pair of bumbling cops.
