Camera History

1. Camera obscura is just a whole on the side (wall) of a box shape. Then light is focused through the whole. Once the light is focused an image on the opposite side of the hole, a image appears of the outside of the hole appears inside on the wall upside down.

2. In the 17th century Isaac Newton and Christian Huygens perfect the understanding of optics and the process of making high quality glass lenses, this made man a step closer into making modern cameras.

3. In 1827 Joseph Nicéphore Niépce found the missing piece to the puzzle. He added film, which allowed for successful photographs. This step made a modern camera.

4. Modern cameras still work the same as the first cameras made. Light passes through the lens, into the camera, and exposes the film. This process makes a photograph, same as every camera ever made.

5. Digital cameras use the same concept in making a photograph, except the instead of film, digital cameras use CCD, which is an electric sensor. CCD then stores the photograph in a reusable computer memory device. In the end its still of the same concept, just cheaper, and more environmentally friendly.

6. The difference between auto and program is simple. Auto does everything other then point and shoot. It'll handle flash and exposure, while program allows for a little bit more control with flash and a few other settings.

7. Portrait mode in a camera is the attempt to blur the background of the photo. The way it works is the camera does it self using the fastest available lens setting (aperture) 

8. Sports mode is pretty much for taking a picture of anything that is moving at a certain speed that wont allow you to take a good picture. The way it works is the camera it self uses the fastest shutter speed possible.

9.  You should use the half press on a trigger button because its used for many helpful reasons. It makes a faster camera response time, more control over focus, and encourages better composition.

10. This image means no flash, you should use it when the natural light is better then flash.

 11. This is called auto-flash, it'll flash when the camera believes it is needed. You should use it when your not very sure when to use flash or not.

 12. When there is too much light the picture will be washed out, you wont really be able to see it. 

13. If there is not enough light then you just wont plan be able to see your picture.

14. "Stop" re[resents the change in brightness of a light.

15. If there were two suns instead of one the stops brightness would be 1.

16. If there were four suns instead of one the stops brightness would be 2. 

17.Having a longer shutter speed makes more light.

18. Having a shorter shutter speed makes more light.

19. The aperture is like a pupil it controls light.

20. The way the aperture controls the light is by closing to restrict, or by opening to let it through.
