Plant Photography

`Until the recent development of digital cameras, most photography involved the use of films coated with various light sensitive compounds of silver. The sensitivity of certain silver salts to light was known from about 1727, when Johann Heinrich Schulze published his findings in the Nuremburg Academy of Natural Philosophers. But many natural things are sensitive to light. Long ago people noticed the effect of light on green plants, or how it made coloured fabrics fade. It is the effect of light on plants that makes Roman Photography possible.’
