Hello, I am from /ic/ and was wondering how I should begin thinking about black and white colors mathematically? 0 and 1 ??
I'm mainly interested in how images are rendered in binary black and white.

My understanding of math is shit. I took trigonometry three times in college, so now it is the part of math i understand best. Geometric Proofs. fuckin unit circle.
BUT but but MY understanding of math (and the first time i felt joy doing math was in calculus) was doing derivatives.
I basically understood that limits could express the more grey areas of math like the area under a curve and such...
Lastly, thanks in advance for any bully/help/direction! I am working as a pixel artist but am incredibly interested in how visual perception works.
