PHOTOGRAPHY AND CAMERA. [1]

I think most of you is the big fan of photography so
i am going to tell you something about photography...

Definition:
   Photography is the science, application and practice

of creating durable images by recording light
or other electromagnetic radiation, either electronically by means of an image sensor,
or chemically by means of a light-sensitive material such as photographic.

Discovery of camera:

    It was first discover by Thomas Wedgwood...

Around the year 1800, British inventor Thomas Wedgwood
made the first known attempt to capture the image in a camera obscura
by means of a light-sensitive substance.
He used paper or white leather treated with silver nitrate.
Although he succeeded in capturing the shadows
of objects placed on the surface in direct sunlight,
and even made shadow copies of paintings on glass, it was reported
in 1802 that the images formed by means of a camera obscura have been found too faint to produce,
in any moderate time, an effect upon the nitrate of silver.
I like this picture very much.

Black and white:

 I like those old picture black and white.

Originally, all photography was monochrome, or black-and-white.
Even after color film was readily available, black-and-white photography
continued to dominate for decades, due to its lower cost and its classic photographic look.
The tones and contrast between light and dark areas define black-and-white photography.
It is important to note that monochromatic
pictures are not necessarily composed of pure blacks, whites
and intermediate shades of gray but can involve shades of one particular hue depending on the process.
The cyanotype process, for example, produces an image composed of blue tones.
The albumen print process first used more than 170 years ago, produces brownish tones.

hunn its not enough i will tell you lot of things about camera and photography......
I hope you like it.
