Let’s Have some Basic Knowledge about the Camera
Usually fitted
with a lightproof box or container, lens Camera which so that it can be
directed toward the film or the imaging device contained within concentrates it
by gathering incoming light.
All of them less
or more sophisticated versions of the camera with smart camera remote obscura today there are many different types of
camera in use, which to antiquity dates back.
Nearly of the
same basic parts all of them are made up: to control the amount of light
reaching the light-sensitive surface a lens and a shutter, a body (the
lightproof box), a focusing mechanism and to frame the scene a viewfinder.
Control the Light Peeping into the Camera
By reference to
its maximum opening, or aperture the speed of a lens is indicated, through
which light enters the camera with versatile camera trigger.
By an iris
diaphragm (in the center a series of overlapping metal blades with a hole that
form a circle whose diameter as desired can be decreased or increased) inside
the lens this f-stop, or aperture is controlled. The smaller the aperture the
higher the f-stop number and vice versa.
The time during
which light is permitted to enter the camera with camera remote for timelapse is controlled by a shutter. Focal-plane
and leaf-type are two basic types of shutter.
Similar to those
of the iris diaphragm a ring of overlapping metal blades is employed by the
leaf-type shutter, which to the desired degree may be opened or closed. Behind
or in front of the lens occasionally is placed but between the lens elements it
is normally located.
Just in front of
the film plane the focal-plane shutter is located and travelling horizontally
or vertically across the film frame has one or two cloth or metal curtains.
For a good
exposure the proper amount of light (influenced by the relative sensitivity of
the film being used and determined by using a light meter) can be obtained in
conjunction with the width of aperture by adjusting the shutter speed.
