Historically gold bullion has played an important role in the development of photography over the years. With its unique chemical properties gold is invaluable in the process of creating clear and precise images.
Gold was first used in photography by Sir John Herschel in 1842 in his invention known as the 'Chrysotype Process'. He discovered that because gold is a good conductor and is non-corrosive that it is ideal to use as a toner in the printing process resulting in the increased longevity of the resulting photographic print.
Gold is still used nowadays in all digital and film cameras where it can be found in the electronics of the cameras. As the price of gold bullion rises the more expensive it is for camera companies to buy gold and this is often reflected in the fluctuating prices of their cameras.
