Camera History and Information

Here are some facts about the camera:

1.  The camera obscura effect is when in a dark room a small hole is made in one of the walls and through the hole light is focused, and the outside scene is projected upside down on the opposite wall.

2.  During the 17th century Isaac Newton and Christian Huggens perfected the understanding of optics and the process of making high quality glass lenses which helped man get a step closer to creating the modern camera.

3.  A glass lens, a dark box, and film were the parts of the first modern camera by Niepce. 

4.  Light passing through the lens into the camera and exposing the film is what Niepce's camera and the modern camera have in common.

5.  Digital camera's use an electronic sensor called a CCD to capture and image.

6.   The difference between auto mode and program mode is when the camera is in auto mode, it controls all of the flash and exposure, and in program mode you can control the flash and a few other camera settings.

7.    The portrait mode is used to try to blur out the background and it uses the fastest available lens setting.

8.  The sports mode is used to freeze motion and uses the highest shutter speed possible.

9.  When you half press the shutter button is makes the camera have a faster response time, more control over focus, and encourages better composition.

10.   This symbol means disable flash or no flash and you use it whenever there is enough natural light and you don't want to use the flash.


 
11.  This symbol means auto flash, and it is when the camera will automatically fire if it thinks that the picture needs more light.





12.  The photo will be washed out if there is too much light.

13.  The photo will be too dark if there is not enough light.

14.  A stop is a relative change in light.

15.  How many stops brighter is the new planet if there are two sons instead of one?
+1 stop

16.  How many stops brighter is the new planet if there are four sons instead of two?
+2 stops

17.  The effect that a longer shutter lens has is more light.

18.  The effect that a shorter shutter speed has is less light.

19.  The aperture controls the light that goes on the film.

20.  When adjusting the aperture you can increase the amount of light by telling the camera to use smaller f-stop numbers.
