I am currently putting together a piece that links the optical work of Christoph Scheiner (1573-1650), the invention by Marvin Minsky in 1957 of the confocal microscope, pinhole camera art, my own confocal images of shaving foam and structured light microscopy. The common theme is looking through a pinhole.
First a lovely pinhole image byChristian Poncet (examples
Here) -
And also my own confocal microscopy images through a fluorescently labelled shaving foam - as a function of time.
