CAMERA HISTORY

1-    This effect is achieved by making in a wall one hole and you need to put a lens for that the light can focus on the object you want to take the photo on the other side of the room and for that you need the room dark.

2-    Isaac Newton and Christian Huygens perfected the understanding of optics and the process of making high quality glass lenses.

3-    He added *film* to create the first successful photograph, A glass lens, a dark box, and film.

4-    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. Photographs are stored on reusable computer memory devices.

6-    Auto the camera will completely control flash and exposure and program automatic-assist, just point and a few other camera settings.

7-    Portrait mode is used for to attempt to blur out the background, camera will try to use the fastest available lens setting (aperture).

8-    Sports mode is used to freeze motion, camera will use the highest shutter speed possible.

      9-You should use a half press on the trigger button because that helps to have a focus lock because that tell the camera that you are almost ready to take a shot and to be prepared, triggering the following things to happen.
10- 

   Means that the photo will be taken without flash. And you would use it when the room or the place has enough light.

     11- Means that the photo will be taken with flash. And you would use it when the room or the place are dark because you want more light. 

12-    If there is too much light in the picture will be washed out.

13-    If there is not enough light and the picture will be to dark. 

14-    A stop is a relative measurement of light and it came from the early history photography and represents a relative change in the brightness of light.

15-    The planet is one stop brighter if there is two sons instead one. 

 16-    If the new planet is four sons instead of two there are 2 stops brighter. 

 17-    Longer shutter speeds more light. 

 18-    Shorter shutter speeds less light.

 19-The aperture controls light by closing up to restrict light, and opening up to let it through.

 20-You can increase the amount of light by moving from f16 to f8 two stop brighter.
