Noise gradients inside pixel spaces without photographic information (2019).
How do you make (a photograph) (without a camera) in space that is increasingly electronic, mathematical, and abstract?
And what remains if our precious data is lost?
“The original meaning of “noise” was “unwanted signal”; unwanted electrical fluctuations in signals received by AM radios caused audible acoustic noise (“static”). By analogy, unwanted electrical fluctuations are also called “noise”. 
Image noise can range from almost imperceptible specks on a digital photograph taken in good light, to optical and radioastronomical images that are almost entirely noise, from which a small amount of information can be derived by sophisticated processing. Such a noise level would be unacceptable in a photograph since it would be impossible even to determine the subject.”–Wikipedia
