Camera History



"The Camera"

1. The "camera obscura" affect is when a scene is projected (upside down) on an opposite wall. It is achieved by making a small hole in the wall where light is focused through into the dark room.
2. In the 17th century man created glass lenses which took them a step forward in the creation for modern camera.
3. A dark box, glass lens, and film were used to create the first modern camera.
4. The process of taking the photograph is still the same, light passes through the lens, into the camera, and exposes the film. The end results will always be a picture.
5. Digital cameras capture images with an electronic sensor called a CCD.

"Camera Modes"
6. In auto mode, the camera will completely control the flash and exposure. Unlike auto mode, in program mode you will have control over flash and a few other camera settings.
7. Portrait mode is used when you would like to blur out the background. To do this, the camera will try to use the fastest available lens setting.
8. The sports mode is used for when you would like to take a freeze motion shot. To do this, the camera will use the highest shutter speed possible.

"The Half Press"

9. Photographers should use the half press technique because it's a faster-full press response and it allows the photographer to freeze the point of focus before taking the shot. It has more focused results.

"Controlling Flash"

10. The symbol means the flash is disabled. You would use this when you would like to use the natural light to make a more dramatic shot.
11. The symbol means the auto-flash is enabled by default. The camera will use this when it thinks it needs more light.

"Introduction to Exposure"

12. If there is too much light in the photo, it will be washed out.
13. If there is not enough light in the photo, it will be too dark.

"Stops and Exposure"

14. A "stop" is a relative measurement of light.
15. It would be 1 stop brighter.
16. It would be 2 stops brighter.

"Shutter and Aperture"

17. A longer shutter speed has the affect of more light.
18. A shorter shutter speed has the affect of less light.
19. The aperture controls the lights opening. 
20. You can increase the amount of light through the aperture by changing it to a smaller F-stop number.
