Did the invention of the camera influence artists?
Yes, it certainly did. Some painters used a camera instead of sketching in front of a subject. Later on, around 1900, we find painters (and groups of painters) who held the view that painting should not try to achieve the same thing as photography, i.e. to copy reality. So there are all the -isms that are not realistic.
How and why did the invention of the camera influence the popularity of impressionism and abstract art?
The invention of the camara influenced the popularity of impressionism and abstract art because when they invented the camera they did something very important by the trigger of that thing it did something else important.So the inventor of the camera became famouse.While his wife, Chelsea Angustina, started to create more and more art that he could sell.
Actually, the camera obscura WAS used by artists to assist in painting before the advent of photography. The artists would sit in a darkened room with a pinhole in one side. The image (rendered upside down) projected on the wall was used by the painters, rather than looking at the scene itself. Seriously? You've gotta be kidding! Common sense, man! When the camera was invented photography came about. They went hand in hand.
