Camera Histoy
1.The effect came to be known as the "camera obscura" which is Latin for "dark room". This was the first camera. The hole acted like a lens, focusing and projecting light onto the wall of the dark chamber.
2.In the 17th century, 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.Then in 1827 Joseph Nicéphore Niépce added the final touch. He added *film* to create the first successful photograph, and the modern camera was born
4.Light passes through the lens, into the camera, and exposes the film. And guess what? The end result is still a photograph.
5.cameras capture the images with 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,
8.Sports To freeze motion, camera will use the highest shutter speed possible.
9.you should use the half bottom because its
faster camera response time
more control over focus
encourages better composition
10. The symbol means "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. The symbol means "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 there is too much light, the picture will be washed out.
13. If there is not enough light, the picture will be too dark.
14. The term "stop" is used in every aspect of photography to represent a relative change in the brightness of light.
15. 1 stop brighter
16. 2 stops brighter.
17. A longer shutter speed has more light.
18. A shorter shutter speed has less light.
19. Before light reaches film, it must pass through an opening called an "Aperture". The aperture is like a pupil. You can control the aperture by setting the "Aperture Opening", also known as an F-Stop.
20. Smaller F-stops numbers = larger openings. Larger openings = more light.
