Camera History and Camera Parts

1. Camera obscura is inside a completely dark room, a tiny hole is created in one wall. Through the hole light is focused, and the outside scene is projected (upside down) on the opposite wall.
2.  the modern camera came one step closer when Isaac Newton and Christian Huygens perfected the understanding of optics and the process of making high quality glass lenses.
3. The parts of the first modern camera were a glass lens, a dark box, and film.
4. Light passes through the lens, into the camera, and exposes the film.
5. Cameras use digital film to capture images also  an electronic sensor called a CCD.
6. Auto - the camera will completely control flash and exposure. Program - automatic-assist, just point and shoot.
7. Portrait To attempt to blur out the background, camera will try to use the fastest available lens setting (aperture).
8. Sports To freeze motion, camera will use the highest shutter speed possible.
9. Faster camera response time, more control over focus, and encourages better composition.
10. Disabled Flash no flash. There are many cases where you may not want flash at all. The mood of the photograph can sometimes be more dramatic when the natural light is used.
11. Auto-Flash in most camera modes, Auto-flash is enabled by default and will automatically fire if the camera thinks it needs more light.
12. If it's to light the picture will be washed out.
13. Not enough light and the picture will be too dark.
14. "Stop" is a relative measurement of light, also you can say the change in the brightness of light.
15. There are now 4 new planet.
16. There are now 8 new planet.
17. Longer shutter speeds = more light
18. Shorter shutter speeds = less light
19. Before light reaches film, it must pass through the aperture.
20. Like the pupil in a human eye, the aperture on a camera controls light.
    It does so by closing up to restrict light, and opening up to let it through.
    
    
    
    
    

    Aperture- an opening, hole, or gap

    shutter- to keep light out

    exsposure- the process of allowing light reach the film

    Depth of field-the distance between the nearest and the furthest objects that give an image judge to be in focus in a camera

    F-stop-a camera setting corresponding to a particular f-number

    focal Length- the distance between the center of a lens or curved mirror and its focus
