Photography: photography (Photography) comes from the word photos (light) and Graphia (write/draw), so that it can be interpreted that photography is a technique of drawing with light. On the basis of these, it is clear that very light plays an important role and became the main source of getting the picture. SLR camera: camera SLR (Single Lens Reflex) or D-SLR (Digital) is a camera with a viewfinder (viewfinder) that gives the image in accordance with the point of

view of the lens through the reflection of the mirror located behind the lens. In general the camera always has the look of a different viewfinder with the lens viewing angle because the viewfinder is not in line with the point of view of the lens. As discussed earlier, the fotgrafi is closely related to the light, then the camera function to set the light captured image sensors (image sensor in a digital camera or film on a conventional camera). To set the light, there are two fundamental things in the camera, the Shutter
Speed (shutter speed) and Aperture
(Diaphragm). Shutter Speed: Shutter speed or aperture is the camera window opening so that the speed of light can enter into the image sensor. Shutter speed than the unit is seconds, and extremely light conditions depending on the time of the photo shoot. Such a bright light during the day, then the shutt.er speed should be adjusted to be faster, such as 1/500 of a second. As for the evening light is less, then the shutter speed should be adjusted to be much longer, such as 1/5 seconds. It is at once explain why the photo at night tends to be opaque, that slower shutter speed allows the movement of the camera due to the vibration of the hand made light shifted so that the photos being blurry/blur
