Speedlights flash, the picture is taken, the film automatically advances, the shutter is cocked, and all is in readiness for the next child in the line.

As late as 1905 a landscape taken with "the deepest ray filter" showing massive white clouds against "a sky as seemingly black as that of midnight" was criticized as false, and the amateur who sent it to Camera Craft magazine was advised to try to correct the distortion in printing the negative. When commercial large-scale production of panchromatic film which film was made possible in the 1920s, through the use of newly discovered dyes, the new emulsion soon came to be universally used.
