Camera History

1. The "camera obscure" effect is what happens when a hole is cut in a wall in a completely dark room.   If the effect occurs, then light is focused through that hole, and on the opposite wall, the outside is upside down.
2. In the 17th century, Isaac Newton and Christian Huygens invented high quality lenses, an important thing to forward our advancements to modern cameras.
3. The first parts of a camera (invented by Niepce), were glass lens, dark boxes, and FILM.  Film was the thing that actually recorded what images cameras took.
4.  Modern cameras aren't all completely different from Niepce's cameras.  Digital cameras today have light pass through lens, into cameras, to expose film.
5.  Of course, just because they have some similarities with old cameras, it doesn't mean digital cameras don't work on an entirely different level. Digital cameras capture images with an electronic sensor called a CCD. Obviously i'm not an expert on photography so I have no clue what a "CCD" is.  I do know that we use it because it's cheaper, and more efficient.  Not to mention it's much more environmental friendly.
6.  "Auto mode" makes the camera control the flash and exposure, while "program mode" allows you to control flash, exposure, and a few other things.
7.  The "Portrait" mode on a camera blurs out the background to the best of its ability.  This is done by selecting the closest available lens.
8.  The "Sports" mode option is used to get as clear of a photo as possible.  It freezes motion, and uses highest "shutter" speed as possible. I have no clue what "shutter" is.
9.  The "half press"is when you just tap the trigger until it comes awake and aimed at your target.  Think aiming down your sights and preparing to fire.
10. That symbol means the flash is turned off.  It's often a good thing to have on if you want drama in your shots. (camera shots)
11.  That symbol means that the camera will decide if your photo needs a flash or not.
12.If there's too much light when you take a picture, your photo/s will be "washed out."
 13.If there's not enough light, your photo/s will be too dark.
 14. A "stop" is a relative measurement of light.  It can be anything.  One more lightbulb, one less candle, and so on.
15.  I admit I hit the "show answer" button.  I was going to say 2 times for some reason (might be the heavy metal blasting my ears out), but it's one stop more because it's ONE more sun.
16.  4-2=2.  simple as that.  4 suns instead of 2 is 2 stops greater.
17.   longer shuttle speeds=more light
18.   shorter shuttle speeds=less light
19.  The Aperture  of a camera controls the amount of light.
20.  When adjusting the Aperture, you can increase the amount of light by increasing the opening
