The September 1964 edition of “Practical Photography” published the above images of mine. Months earlier, its sister publication “Photo News Weekly” had published similar images by me.

These were “physiograms“, (swinging light images or “pendulum photographs“), but apparently unlike any that had been published before. They are possibly unlike any that have been published since. This is their story.



A friend (Peter Hunt) and I were studying “Mathematics, Further Mathematics, & Physics” at school. We set about applying mathematics to the topic. To do so, we had to swing the camera too. This transformed the possibilities, and this series of articles attempts to provide the basis for anyone else to build on what we started.

Here are 2 galleries: one of the original monochrome images, and the other of more colourful processed images. (See the examples above and below).
