Boolean Logic is not human.

Boolean logic is very simple. It expanded enormously in the computers. It works with just two propositions: true or false,  “1” or “0”. This is how work computers, hardware and software.
As an author ignorant of Boolean mathematics, but passionate about monochromatic photography, I wanted to experiment with the visual and subjective effects of reducing the image to two colours, black and white.
I took a analogue photograph, scanned with the digital camera and I opened it in Photoshop. I set up two layers: a curve and a posterization. It is therefore possible to change the curve to display different degrees of posterization. I set the second level with a threshold of "2" (black and white) and played with the curve until I obtained an image with representative content of the shot, at least for my eye and brain.

The second test was the opposite: playing with the curve and the "2" level posterization, raising the tones of black, i.e. "true", in order to reveal all the objects contained in the shot, and in reality. It is a sort of expansion of the truth, the truest truth. You can continue to widen the black threshold until it covers the entire image. At that point a black rectangle remains, which may be true, but loses meaning for any human being (perhaps with exception of a great artist). The following is the image in which the "true" (Black) predominates over the white (False), maintaining a modicum of meaning for the human mind.

But the true significant content for a human is when posterization is forced to take on three levels, namely White, black and grey. Let's get out of Boolean logic, which is not human, and give man back his beloved grey, neither true nor false, but human.
