How were cameras back then?

Answer 1

It is believed that the camera was invented during the early 1500's. And I'm not talking about the high technology, snapshot camera we have today lol. The first unsophisticated camera was called the camera obscura, which meant dark chamber. Artists were the only people who used the camera as a tool mostly to help them sketch scenery. They would trace the shapes and lines, and then color the picture they took.

The camera worked by light entering a tiny hole on one side of the dark box that was big enough to fit a grown human being. The light formed an image on the opposite wall. The picture was an upside-down image of the scenery outside the box. .-.

During the 1660's the length of the camera was reduced to around two feet. A lens placed over the holes made the image larger and sharper. A mirror inside the camera reflected the image onto a piece of ground glass at the top of the camera. The camera obscura provided a way to project an image on a wall or a screen, but this procedure wasn't permanent. Artists still had to trace the image to preserve it. THX :D
