Sound / Eigengrau
'Own gray' or 'own light' is what you see when nothing is there. Modern language would call it 'visual noise' and label it something undesirable in photography. We even have invented editing software and photography techniques to reduce it for its much sought after bright, white light sister. What is it about eigengrau that makes us so uncomfortable? Next time you are waking up or going to sleep, lie in bed and search for the absence of light and there lies the ever omnipresent, eigengrau.
