4. Definition of single use camera
 Single Use Cameras are the simplest cameras. They
contain a roll of color film encased in a recyclable
cardboard box. They have a single shutter speed and a
fixed-focus lens. These cameras can be bought with a
variety of features, including built-in flash and water
resistance. The whole camera has to be taken to the
photo finisher so the film can be processed. The camera
is recycled. These cameras cost around $15 and should
not be used for serious photography. They are
convenient for vacations and times when you find that
the other camera has been forgotten.

5. Difinition of compact lens shutter
camera
 Compact Lens-Shutter Cameras come in three
varieties: single focal length, dual focal length,
and zoom. Some have fixed focus, meaning that
the focus is fixed at a point that produces sharp
images starting from about 5 ft. away and
continuing to infinity. Other cameras offer
infrared auto focusing. Some models offer
features like red-eye reduction flash and several
automatic shooting modes. More serious
photographers usually prefer to have more
control over the pictures they take.

6. Definition of bridge camera
 Bridge cameras are intermediate cameras.
They bridge the gap between "point and
shoot" cameras and the more serious or
complicated models. They have different
lenses and many offer a red-eye reducing
flash. There is only a limited range of lens
focal length that can be used with these
cameras

7. Definition of range finder
 Rangefinders are compact, lightweight
cameras that are often used for serious
photography. They offer interchangeable
lenses and allow photographers to control
shutter speed, lens aperture, focusing,
and exposure. Some disadvantages are
that it is limited in focal length (ranging
from 21mm-135mm) and they tend to be
expensive.

8. Definition of twin lens reflex
 The twin lens reflex is a medium-format camera (one
that uses film larger that 35mm). It is fitted with two
lenses which both have the same focal length, one
mounted atop the other. The lower (taking) lens focuses
its image directly on the film, while the image produced
by the upper viewing lens is reflected through 90
degrees by a mirror, and brought to focus on a horizontal
ground-glass focusing screen. The light paths to the
focusing screen and the film plane are equal, so that if
the photographer brings the scene on the focusing
screen to sharp focus, the image on the film plane will be
equally sharp.

9. Definition of single lens reflex
 The SLR requires one lens for both viewing and
creating the photo. A sophisticated camera that
offers full manual control of exposure an focus.
SLR cameras will accept interchangeable
lenses, add on flashes, motor drives, and other
accessories. There are also AF (auto focus)
SLR's. These can be set in a number of different
modes to ease picture taking. These cameras
are typically used by professional
photographers.

10. Definition of digital camera
 A digital camera records and stores
photographic images in digital form. Many
current models are also able to capture sound or
video, in addition to still images. Capture is
usually accomplished by use of a photosensor,
using a charged coupled device (CCD).These
stored images can be uploaded to a computer
immediately or stored in the camera for to be
uploaded into a computer or printer later. Images
may also be archived on a photographic
compact disc or external hard disk.

12. What is digital photography
 The art and science of producing and manipulating digital photographs --
photographs that are represented as bit maps. Digital photographs can be
produced in a number of ways:
 Directly with a digital camera
 By capturing a frame from a video
 By scanning a conventional photograph
 Once a photograph is in digital format, you can apply a wide variety of
special effects to it with image enhancing software. You can then print the
photo out on a normal printer or send it to a developing studio which will
print it out on photographic paper.
 Although the resolution of digital photos is not nearly as high as photos
produced from film, digital photography is ideal when you need instant, low-
resolution pictures. It's especially useful for photos that will be displayed on
the World Wide Web because Web graphics need to be low resolution
anyway so that they can be downloaded quickly.
