Let’s create an image that displays the entire range of shades of gray using the following rule: pixel at x, y is colored using the grayscale x+y. That is, a pixel in the image at 0, 0 will get the shade 0+0=0 or black, which the pixel at 50,50 will get the shade 50+50=100 which will be a midrange gray.

Example: My negative picture would try to use the grayscale image, and not the original photo. The most rewarding part was slowly understanding how pictures are modified in a digital space. I know that seems very simple, but it never occurred to me before how different digital art is when compared to a physical sketch or painting."
