The Camera

1) The "camera obscura" effect is inside of a completely dark room, when a tiny hole is created in a wall and light is focused through that hole, the outside scene is projected upside down on the opposite wall. The hole, acting like a lens, focused and projected light.

2) The modern camera became one step closer when Isaac Newton and Christian Hughes perfected the science of optics and designed high quality lenses from glass.

3) The parts of the first modern camera invented by Niepce was a glass lens, a dark box, and film.

4) Modern cameras have a lens, and use film, digital or tangible also.

5) Digital cameras use light that passes through a lens, into the camera, and to the film.

6) The Automode allows the camera to completely control functions like flash and exposure. On the other hand, Program mode is auto-assist, which allows the user to usually be able to control cash and other camera settings.

7) Portrait mode is used to blur out the background by using the fastest aperture setting.

8) Sports mode is used to capture moving objects. It uses the highest shutter speed possible to try and freeze the motion.

9) The user should do a half-press on the trigger button to focus the camera (if using autofocus).

10) The symbol means that the flash is disabled. When the photographer wants to manually affect the mood or use other sources of light, this function will be used.

11) Auto-flash is used is most camera modes. It is enabled by default and is automatic.

12)  When there is too much light, the picture will appear washed out.

13) If there is not enough light, the image will be very dark.

14) A "stop" is a relative measurement of light.

15) A new planet with two suns would be one stop brighter.

16) If there were four suns instead of one, our planet would be 2 stops brighter.

17) A longer shutter speed allows more light.

18) A shorter shutter speed allows less light in.

19) The aperture controls how much light passes through into the photo, like a pupil.

20) When adjusting the aperture, the photographer needs to also adjust the shutter speed, by taking a stop and giving a stop to the other.
