Abstract

<p>In the era of wet plate photography of 1860, Sir Herschel, who was a scientist of universal and a mogul of photographic chemistry, proposed the concept of “Instantaneous Photography” that is to leave the video to offspring by recording the moving events in the world. He described that the thechnologies required to instantaneous photography were high sensitivity one to enable the snap-shot of 1/10 second exposure and that of plate replacement within 1/2 to 1/3 seconds. Proposal of a pipe dream had been embodied in the wake of the report of the gelatin emulsion by Maddox in 1871 and the launch of the photographic film by Eastman in 1889. And concept of Herschel led to the popularization of photography as represented by film with lens as “Quick-Snap” and the creation of the cinema industry as the popularization of movies. Today digital photography era, the integration of both still-photo and movie-photo is progressing by both functions are housed in a single camera.</p>
