Man ray created the technique of making photographs through camera less photography made by placing objects or material on photosensitive paper and exposing it to light which he called rayograms a play on his name and the fact that a ray is a type of light. Mann ray’s photograms not only express how the use of light, texture and size can effect the outcome of a photograph turning ordinary objects into something completely different and almost unrecognisable they also show us that photography is more than just being able to take an ok picture .
Unlike photographs set in silver, like in black and white photography, cyanotypes are using a solution of iron compounds.
The photograph can be taken with a camera, like a digital camera, and the resulting photo turned into a negative that can be used to make a cyanotype.
The basic cyanotype recipe has not changed very much since Sir John Herschel introduced it in 1842.shorter exposure times and a longer density range can change an image in many way and my be seen as an easy thing to do, but it is also slightly more complicated to mix and uses more toxic chemicals.
