Camera History

"The Camera"
1.) The "camera obscura" effect worked 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) no the opposite wall.
2.) 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.) Niepce added film to create the first successful photograph, and the modern camera was born, a glass lens, a dark room, and a film.
4.) The latest digital cameras work the same way as their ancestors, light passes through the lens, into the camera, and exposes the film.
5.) Digital cameras capture the images with an electronic sensor called a CCD.

"Camera Modes"
6.) The difference between the Auto Mode and the Program Mode is that in the Auto Mode, the camera will completely control flash and exposure, and in the Program Mode, you can usually control flash and a few other camera settings.
7.) The Portrait mode is used to attempt to blur out the background. The camera will try to use the fastest available lens setting.
8.) The Sports mode is used to freeze motion. The camera will use the highest shutter speed possible.

"The Half Press"
9.) You should do a half press on the trigger button so it could give you faster camera response time, more control over focus,  and encourages better composition.

"Controlling Flash"
10.) No flash, you would use this when it is bright.
11.) Auto-flash, you would use this when it is dark.

"Introduction to Exposure"
12.) If there is too mush light, the picture will be washed out.
13.) If there is not enough light, the picture will be to dark.

"The Universal Stop"
14.) The term "stop" is used in every aspect of photography to represent a relative change in the brightness of light.
15.) The planet is brighter by 1.
16.) The planet is brighter by 2.

"Shutters and Aperture"
17.) Longer shutter speed makes more light.
18.) Shorter shutter speed makes less light.
19.) The aperture is like a pupil.
20.) You can increase the amount of light by having larger openings.
