Why did joesph niepce invent photography?
He couldn't draw. Seriously. When Niepce was alive, a popular
artist's tool was the "camera obscura." If you know what a pinhole
camera is, you're one step ahead of the game here. Instead of using
film, the camera obscura had a sheet of really thin paper in it. An
image appeared on the paper; to make it permanent you traced it
with a pencil. Niepce didn't have a steady-enough hand to make good
tracings, so he invented a way to make the camera do the work for
him.
