The Story Of Flash For Photography

The Story Of Flash For Photography

The arrival of panchromatic emulsions allowed him taking a picture in low light conditions using precisely an artificial light source powered Magnesium The magnesium powder was burnt to generate a flash (bluish) and then illuminate the scene.

Apart from the illuminator magnesium alive, whose drawback was the smoke production and magnesium oxide, in the second half of 1800 was carried out the study of a more comfortable solution, or a closed lamp that could retain the combustion residues akusaraprosound. It was J. Mc Clellan, in 1893, patented a glass bulb (indeed for underwater photography) inside with a wire coated with magnesium. Seven years later, June 14, 1900, Erwin Quedenfeldt patented the first real flash lamp in an electric lamp filament was coated with magnesium and the passage of electricity in the filament causing the power (and therefore the flash) magnesium.

In the meantime, they began to spread the raw fleece dry and this allowed him to make the magnesium flash a transportable object, though still lacking synchronization with the shutter of the camera.

In 1925, the work of Paul Vierkotter, came the revolution it was the predecessor of modern patented flash (remember the cubes that were used a few years ago on analog), Consisting of a glass bulb in which was contained oxygen at low pressure and the incendiary powder based on magnesium. A filament powered by electricity it caused an explosion resulting lighting release for a fraction of a second. Two years after the magnesium was replaced with aluminum foil, and in 1929 was placed on the market the first commercial lamp based on this patent, the work of Johannes Ostermeier and called Vakublitz lamp.now used by all, it is refined.

This was the beginning of the race illuminators in 1930 came the Sashalite, in 1933 the Photoflux whose characteristic was to have a ingrado splash of color to tell the photographer if the glass was damaged or not. This is because, prior to that, many bulbs literally burst creating many damage to the photographer.

They were then created multiple flashes called for example Flashcubes, Magicubes or Flipflash small bulbs placed inside a structure able to get them on fire in sequence.

In 1935 the Exakta SLR (model B) was equipped with electrical contacts for controlling a flash series opens the era of sync, made available on most cameras in the early ’50s.
