However, the film was not qualified for the competition section, because it had been filmed in digital camera format.
The combination of a precision rotator and a digital camera allows the photographer to take rectangular slices of any scene (indoors or outdoors).
Even after that, it was not noisy enough to register on a digital camera.
An advantage of the digital camera was that only a single image file was taken for each focal level and dendritic section (compared to three color slides for photography).
A digital camera photographed the discharge light.
The digital camera is 'played' in time, somewhat like an instrument in the process of gathering material with a specific effect or image movement in mind.
When connected to a digital camera it is sufficiently powerful to allow on-board image processing, and it has the means of interacting with other sensors and actuators with high precision.
Furthermore, the field tests were carried out in good daylight conditions, such that image stabilization was not an issue even with a more sophisticated digital camera.
