Question: when was the first black and white camera invented
Answer: In 1816 Nicéphore Niépce , using paper coated with silver chloride , succeeded in photographing the images formed in a small camera , but the photographs were negatives , darkest where the camera image was lightest and vice versa , and they were not permanent in the sense of being reasonably light - fast ; like earlier experimenters , Niépce could find no way to prevent the coating from darkening all over when it was exposed to light for viewing .
