A. Photography
derived from the Photo ( Light ) and Grafo ( writing /
drawing ) , so that means that photography is a technique of drawing
with light . On
this basis , it is clear that light plays an important role and become
the main source of obtaining images ( without light there would be no
photograph ) .B. SLR camerasSLR
( Single Lens Reflex ) camera or D - SLR ( Digital ) is a camera with a
viewfinder ( Viewfinder ) that provides image corresponding to the
angle of view through the mirror lens which is located behind the lens .
In
general, has the look of a regular camera viewfinder with a different
point of view because the viewfinder lens is not in line with the point
of view of the lens .Photography
is closely related to light ( so to produce an image required the
presence of light , without light there would be no photograph ) , the
camera serves to regulate light captured image sensor ( image sensor in a
digital camera or a film in a conventional camera ) . To
adjust the light , there are two basic points in the camera , the
shutter speed ( Shutter Speed ) and aperture ( diaphragm ) .C. lensIn photography , the lens serves to focus the light to be able to burn catcher medium ( film) . On
the outside of the lens there is usually a three- ring , which ring the
focal length ( lens types for variables ) , aperture ring and focus
ring .LONG LENSFocal length of lens called LengthLength of the lens affects :a. DISTANCE shootingb . viewpointc . ENLARGEMENTd . FACILITY OPENING DiaphragmSpecial lenses :a.

Soft lenses ( commonly called Soft Focus Lens )Various lens
Standard lenses . This lens is also called a normal lens . Measuring 50 mm and gives the character a natural shot .
- Wide Angle Lens ( Wide Angle Lens ) . This type of lens can be used to capture the broad subject in a narrow space . Character of this lens is made subject smaller than actual size . By using this type of lens , in the room we can shoot more people lined up when compared to the standard lens . The shorter the distance the focus , then the width of his views . This lens size beragan ranging from 17 mm , 24 mm , 28 mm , and 35 mm .
Fish Eye lens . Fish eye lens is a wide angle lens with a diameter of 14 mm , 15 mm , and 16 mm . This lens gives a 180 degree view . The resulting warped image .
Tele lens . Telephoto lens wide angle lens is the opposite . This lens function is to hold the subject , but narrow viewpoints . Which includes a telephoto lens is a lens measures 70 mm upwards . Due to the narrow view angle , telephoto lens will blur the surrounding field . But this is not a problem because the telephoto lens is used to bring the views and focus on a particular subject .
Zoom lens . Tandar a combination of lens , wide angle lens , and a telephoto Lesa . O fixed lens size , for example 80-200 mm . This lens is quite versatile and has a wide enough range ang lens . Hence zoom lenses are widely used , because users just set the size of the lens as required .
Macro lens . Used a macro lens to photograph small objects .

D. focus
Focus is part of a set distance lens sharpness so the resulting image is not shaded ..
F. shutter Speed
Shutter speed or aperture is an opening speed of the camera window so that light can enter into the sensor image. Unit than the shutter speed is second, and very dependent on the state of light while shooting. Such a bright light during the day, then the shutter speed should be adjusted to be faster, such as 1/500 sec. As for the evening was a little more light, the shutter speed should be adjusted to be much longer, such as 1/5 sec. This also explains why the photos at night tend to be opaque, that a slower shutter speed enables the camera movement caused by hand-shake to make light shifted so that the image to be blurred / blurry.

G. aperture
Aperture is the term for the lens aperture. When likened to the window, then the diaphragm is Kiray / curtain that can be opened or closed to adjust the amount of light entering. The camera aperture is denoted by the letter F minor and the unit as follows:
f/1.2
f/1.4
f/1.8
f/2.0
f/2.8
f/3.5
f/4.0
and so on ...
The smaller the number, the larger unit aperture lens (f/1.4 bigger opening than f/4.0, f / 2,8 bigger opening than f/16).

The smaller the number, the larger unit aperture lens (f/1.4 bigger opening than f/4.0, f / 2,8 bigger opening than f/16).
Thus, the correlation between shutter speed and aperture is that the larger the aperture the faster the shutter speed, the smaller the lens opening opposite the shutter speed will be slowed.
