So now film became ‘Orthochromatic’; sensitive to green and blue, but still red did not register.Red tones still registered as dark areas in an image.
I don’t want to teach you to suck eggs but it might be beneficial to this topic if we remind ourselves of the history that has led us out of the dark age of non-photography to where we are now; an age that may be described, by the sociologists of many millennia hence, as the beginning of the ‘Photograscene’ era – the era which will not exist without photography.
All early emulsions were only able to record one of the primary colours.
And then in 1941 they introduced a way of making prints from the transparencies so now photographers had a way of reproducing and disseminating visions of the world in something like a natural colour spectrum.
But what was added in the way of colour was deemed by many to ‘take something away’ from the power of a monochrome photographic image.
The reduction in optical data offered by the monochrome image requires greater engagement and subconscious insertion of ourselves into the image than the colour image requires.
In the case of the latter our brains are tricked into thinking that all the information available is there which has a deadening effect on our imaginations rendering the image more a depiction rather than a human interpretation of a scene.
It is a sensation that adds excitement and emotion to our lives.
Everything from the cloths we wear, to the pictures we paint revolves around color.
Nature is colour; man’s imagination can encompass black and white only through the complex combination of the neural system and psychology peculiar to human beings.
Only we humans choose to reduce the values of nature to shades of grey to better represent the externalised manifestation of our innermost vision.
