The camera

1. Explain the " camera obscura" effect. How is it achieved? 

_The effect came to be known as the "camera obscura" which is Latin for "dark room". This was the first camera. The hole acted like a lens, focusing and projecting light onto the wall of the dark chamber.
Inside a completely dark room, a tiny hole is created in one wall. Through the hole light is focused, and the outside scene is projected (upside down) on the opposite wall.


2. What invention during the 17th Century helped man get a step closer to creating the modern camera?

_In the 17th century, the modern camera came one step closer when Isaac Newton and Christian Huygens perfected the understanding of optics and the process of making high quality glass lenses.

3. What were the parts of the first modern camera invented by Niepce?


_He added *film* to create the first successful photograph, and the modern camera was born:
A glass lens, a dark box, and film. 

4.What do modern digital cameras have in common with Niepce’s camera?

_A digital camera is still composed of a lens, a dark box, and film. 


5. What do digital cameras use to capture an image?

_Replacing old-fashioned plastic film, digital cameras capture the images with an electronic sensor called a CCD.
