1)Camera Obscura Effect was the first camera.
2)The hole acted like a lens, focusing and projecting light onto the wall of the dark chamber. 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)Parts of the first modern camera invented by Niepce were a glass lens, a dark box, and film. 
4)Replacing old-fashioned plastic film, digital cameras capture the images with an electronic sensor called a CCD.
6)"auto mode"The camera will completely control flash and exposure. "Program mode"automatic-assist, just point and shoot. Unlike full auto mode, you can usually control flash and a few other camera settings.
7) "Portrait mode" to attempt to blur out the background, camera will try to use the fastest available lens setting.
8)"sports mode" is use to freeze motion, camera will use the highest shutter speed possible.
9)A half-press will tell the camera that you're almost ready to take a shot and to be prepared, triggering the following things to happen.

12)Too much light and the picture will be washed out.

13)Not enough light and the picture will be too dark. 

14) stop is a relative change in the brightness of light.

15)If you start with a single lightbulb and then add another bulb, the light intensity will increase by one stop.

16)To increase the light by another stop you would need to double the light for a total of 4 bulbs,and so on..

17)Longer shutter speeds = more light
18)shorter shutter speeds = less light
19)Before light reaches film, it must pass through an opening called an "Aperture"
20Smaller F-stops numbers = larger openings larger openings = more light
