"Pinhole Cameras"
This is the best one of the only two PinHole Images I have ever made (and its reverse image). At the time I calculated the f/ratio at 122.5 and exposured the paper for 30 seconds.
The above image was exposed at 5:10pm facing North from what was then TCJC-NE Campus' Photo Lobby (2nd floor of the SUB).
The image below is a reverse image I made in MS-Painbrush after scanning.
