ppt of photography to know much better about photography

1. Photography is the science, art, 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 film. Typically, a lens is used to
focus the light reflected or emitted from objects into
a real image on the light-sensitive surface inside a
camera during a timed exposure

2. Photography is employed in many fields of science,
manufacturing (e.g., photolithography), and business, as well
as its more direct uses for art, film and video production,
recreational purposes, hobby, and mass communication.

3. A camera is an optical instrument for recording or capturing
images, which may be stored locally, transmitted to another
location, or both. The images may be individual still
photographs or sequences of images constituting videos or
movies. The camera is a remote sensing device as it senses
subjects without physical contact. The word camera comes
from camera obscura, which means “dark chamber” and is the
Latin name of the original device for projecting an image of
external reality onto a flat surface. The modern photographic
camera evolved from the camera obscura.

4. The functioning of the camera is very similar to the functioning of the
human eye. The first permanent photograph of a camera image was
made in 1826 by Joseph Nicéphore Niépce.

5. Digital photography is a form of photography that uses
cameras containing arrays of electronic photodetectors to
capture images focused by a lens, as opposed to an exposure on
photographic film. The captured images are digitized and stored
as a computer file ready for further digital processing, viewing,
digital publishing or printing.Until the advent of such
technology, photographs were made by exposing lightsensitive
photographic film and paper, which was processed in liquid
chemical solutions to develop and stabilize the image. Digital
photographs are typically created solely by computer-based
photoelectric and mechanical techniques, without wet bath
chemical processing.

6. Digital photography is one of the several forms of digital
imaging. Digital images are also created by non-photographic
equipment such as computer tomography scanners and radio
telescopes. Digital images can also be made by scanning other
printed photographic images or negatives.

7. Fine-art photography is photography created in accordance
with the vision of the artist as photographer. Fine-art
photography stands in contrast to representational
photography, such as photojournalism, which provides a
documentary visual account of specific subjects and events,
literally re-presenting objective reality rather than the
subjective intent of the photographer; and commercial
photography, the primary focus of which is to advertise
products or services.

8. the term “fine-art photography” has no universally agreed
meaning or definition: rather, it refers to an imprecise category
of photographs, created in accordance with the creative vision
of the cameraman

9. Wildlife photography is a genre of photography concerned
with documenting various forms of wildlife in their natural
habitat. It is one of the more challenging forms of photography.
As well as requiring sound technical skills, such as being able to
expose correctly, wildlife photographers generally need good
field craft skills. For example, some animals are difficult to
approach thus a knowledge of the animal’s behavior is needed
in order to be able to predict its actions. Photographing some
species may require stalking skills or the use of a hide/blind for
concealment.

10. While wildlife photographs can be taken using basic
equipment, successful photography of some types of wildlife
requires specialist equipment, such as macro lenses for insects,
long focal length lenses for birds and underwater cameras for
marine life. However, a great wildlife photograph can also be the
result of being in the right place at the right time.
