focus on photography
1. What can photography and camera capture?
Photography gives us many ways to view the world and glimpses of how others view it. Through photography we are able to freeze time and see the invisible in everyday life. We can record distant objects like starts and galaxies or capture the molecules and atoms that compose the very fabric of existence. Cameras have recorded both the horror of war and the miracle of birth. Photographs have changed laws and lives
2. Explain how a camera works?
A camera is basically a lightproof box with an opening to admit light and a device that focuses light onto light-sensitive material to record an image.
3. Define lens
Lens is a group of shaped glass elements held together in a plastic or metal tube. This lens can be just a tiny hole, called a pinhole, which acts like a lens and admits light into the otherwise lightproof box. The lens projects the light through the box onto light-sensitive material, resulting in a recorded image called an exposure.
4. Define shutter
Shutter (either in the lens or in font of the light-sensitive material) is a mechanical door that opens to admit light and then closes.
5. What light sensitive material is found I digital cameras?
The light-sensitive material can be film, which is composed of very thin layers of microscopic grains of silver salts, silver chloride and/or silver bromide, suspended in gelatin coated on a flexible plastic base.
6. When and where was the first successful permanent photograph made?
The first successful permanent photograph was made in France in 1826 .
7. Who was George Eastman and why was he influential to photography?
George Eastman changed the nature of photography. In 1888, he made the first mass-market, point-and-shoot camera, called the Kodak. One year later, he introduced a new version of his Kodak camera that used a roll of film. It was a simple box camera preloaded with enough film to make 100 exposures. His invention made photography accessible to anyone, professional or amateur.
8. What is camera obscura and how does it work?
Camera obscura is a name of the first camera. They were designed around phenomenon of pinholes, which can project upside down and backward images onto a surface.
9. Why did it take hundreds of years the camera obscura was developed for the first photograph to be made?
It take hundreds of years the camera obscura was developed for the first photograph to be made is because light travels in a straight line, when light rays are reflected from a subject or scene through a small hole in thin material, they cross and reform on another surface as an upside-down, projected image.
