Photography (Photography) derived from the Photo (Light) and Grafo (writing / drawing), so it can be interpreted 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 image results).
B. SLR Cameras
SLR (Single Lens Reflex) or D-SLR Camera (Digital) is a camera with a viewfinder (Viewfinder) that gives the image according to the angle of view through the lens reflection mirror located behind the lens. In general, a regular camera has a viewfinder display of different viewpoints because the viewfinder lens is not aligned with the viewing angle lens.
Photography is closely related to light (so to produce a picture is necessary to light, without light there would be no photo), the camera serves to regulate light captured image sensor (image sensors in digital cameras or 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).
In photography, the lens serves to focus the light to be able to burn the catcher medium (film). On the outside of the lens there is usually a three-ring, which ring the focal length (lens type variable), diaphragm ring and focus ring.
Focal length of the lens commonly called Length
The length of the lens affects:
a. DISTANCE shooting
d. FACILITIES aperture
a. Macro lens (usually called Macro Lens)
b. Increasing the length of the lens (usually called Tele Converter or Extender)
c. Perspective correction lens on the subject
d. Soft lenses (commonly called Soft Focus Lens)
Standard lenses. This lens is also called a normal lens. Measuring 50 mm and give 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. The character of this lens is made the subject of a smaller than actual size. By using this type of lens, in the room we can shoot more people lined up when compared with a standard lens. The shorter the distance of the focus, the more wide-view. This lens beragan sizes 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 provides a 180 degree view. The resulting warped image.
Tele lens. Telephoto lens wide angle lens is the opposite. The function of this lens is to get closer to the subject, but narrowing the viewing angle. Which includes a telephoto lens is a lens measuring 70 mm upwards. Due to the narrow view angle, telephoto lens will blur the surrounding field. However this is not a problem because a telephoto lens is used to bring the views and focus on a specific subject.
Zoom lens. A combination of tandar lens, wide angle lens and tele lesa. Idak lens fixed size, for example 80-200 mm. This lens is quite flexible and has a fairly wide range ang lens. Therefore, the zoom lens is widely used, because users turn the lens size as required.
Macro lens. Macro lens used for photographing small objects.
Focus is part of the set distance sharpness of the lens so that the image produced is not shaded ..
F. Shutter Speed
Shutter speed or aperture is an opening speed camera window so that light can enter into the image sensor. Unit than the shutter speed is seconds, and depends on the state of the 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 evenings are light less, then the shutter speed should be adjusted to be longer, such as 1/5 seconds. This also explains why the photograph at night tend to be opaque, that a slower shutter speed allows the movement of the camera due to hand shake to make light shifted so that the image becomes blurry / blur.

Photos with fast shutter speed
Photos with fast shutter speed
Aperture or diaphragm is a term for the lens aperture. If likened to a window, then the diaphragm is kiray / curtains that can be opened or closed to adjust the amount of light entering. On the camera aperture is denoted by the letter F minor and the units as follows:
f / 1.2
f / 1.4
f / 1.8
f / 2.0
f / 2.8
f / 3.5
f / 4.0
The smaller the number, the greater the unit aperture lens (f / 1.4 bigger opening than f / 4.0, f / 2.8 bigger opening than f / 16).
The aperture on the lens image
The aperture on the lens image
Thus, the correlation between shutter speed and aperture is that the larger the aperture, the shutter speed will be faster, otherwise the smaller the aperture, the shutter speed will be slowed down.
a comparison result dg photo wearing f numbers of small and large f number
note the wide range of sharp space on the third photo above. In large aperture sharp narrow space and so on.
Use a large aperture (small f number) to isolate the disturbing background. Use a small aperture (large f number) for shooting landscapes (scenery).

In accordance with its meaning, interpolation is one of the methods used to enlarge the size of the image with pixel multiply duplicated image size becomes larger. Usually interpolation image when viewed with care will decrease the sharpness of the image as it is not the original results of the sensor output.

L -> short for "Luxury", commonly spoofed into "Disallow". The lens is a Canon L-series lenses are at the top. Made with optical-optical quality choice, also has a good build quality and sturdiness. Lens series is characterized by a red bracelet in front of the neck of the lens. L stands for luxury aka high quality lens that luxury.
DO -> short for "diffractive Optics". This series lenses when compared with other lens that has a focal length and maximum aperture of the same usually have a smaller form factor and lighter weight. Canon also to claim this DO series lenses have a better ability to cope with chromatic aberration. This lens is marked with a green bracelet at the front of the lens neck. Until now, the new Canon produces two kinds of diffractive optics lens with this.
EF -> Canon lens mount since 1987, previously named FD mount. Additional -S behind is short for Short Back Focus. Lenses with this series has a 'stern' more sticking so could not get into the body fullframe. The design is designed for non-fullframe body (APS-C) that has a smaller image circle than normal EF series lenses. If forced mounted on the body fullframe (both aided by the extension tube or other means), it will produce images with severe vignetting due to the range of the image circle is not to cover the entire frame.
IS -> stands for "Image Stabilizer". Vibration dampers on lens technology that enables the lens to stabilize the hand vibration that can cause shaking photo. Ability IS usually measured with a stop rating, where the higher the number the rating, the better the ability of the IS lens in stabilizing the vibration.
USM -> stands for "Ultra-Sonic Motor", can be spoofed into "To All the Moment". AF lens with this bike usually has faster autofocus capability and silent so as to capture the moment with better and more accurate.
EF-S: the type of vatting / pangkon / bajonet / mounting
