What exactly is a negative image and why does the negative of normal seem to be only blue and white?
In: Biology
Negative images take place back in time, when photography was argentic. It was the original picture taken on the photosensitive film, with “reverse colors”, you had to project it on argentic paper (silver tinctured paper) and processed it through chemical bath to reveal the picture. The colors on negative images are the opposite to what you’re seeing for real. I white appears black, black is white, skin tones are bluish… And so on… It have something to do with light absorption and reflection.
