Recording the Waveforms of the Luminous Flux and Ignition Current of Flash-Bulbs and Investigating the Working of Synchronous Contacts

  • J. Czech

Abstract

The eye reacts only to the incidence of luminous radiation, but photographic film reacts to the work performed by the light. It is only luminous intensity which stimulates the eye, but the film integrates the effect of radiant energy over a period of time; the density of the image produced on film therefore corresponds to the product of intensity and time, the work done by the light.
