Focus On Photography
1. What can photography and camera capture?
Photography gives us many ways to view the world. It is able to freeze time and see the invisible in everyday life, capture every single detail. Cameras have recorded both the horror of war and the miracle of birth.
2. Explain how a camera works?
A camera is basically a lightproof box with an opening to admit light and a device that focuses the light onto light sensitive material to record an image. This lightproof box can be made simply of cardboard or the latest technological wonder.
3. Define lens
Lens is a group of shaped glass elements held together in a plastic or metal tube. This lens can also be just a tiny hole, called pinhole, which acts like a lens and admits light into the otherwise lightproof box. The lens projects light through the box onto light sensitive material, resulting in a recorded image called an exposure.
4. Define shutter
Shutter is in the lens or in front of the light sensitive material, it is a mechanical door that opens to admit light and then closes.
5. What light sensitive material is found T digital cameras?
The light-sensitive material can be film, which is composed of a very thin layers of microscope 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 by Joseph Nicephore Nicepce.
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.
8. What is camera obscura and how does it work?
Camera obscura invented hundreds of years before photography itself was invented and it is the first camera. They were designed around the 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 took hundreds of years the camera obscura was developed the first photograph to be made because light travels in 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.
