Toronto. Dr Edgerton experimented with high speed flash in the 1930s. He analysed motion by triggering the flash rapidly as the the subject moved. It was a precursor to electronic flash which was also called strobe light in the mid last century. Strobe was also known as speed light for its short duration. Even books were written about it like, “Strobe – The Lively Light“, which I bought back in the late 1950s. You can even ‘borrow’ the current edition on line.
With modern smart phones, one can experiment with various actions and settings without resorting to the built-in electronic flash. For example, as shown here, the smartphone camera (or digital camera in this case) can be set to ‘PANO’ and the subject tracked as they run past the camera. Not exactly how the PANO setting was intended to be used. You get the idea – change speed, subjects, background, etc. to create a suitable photograph.
