BUY SLR CAMERA ONLINE




CANON EOS 1100D Kit [P] - Camera SLR            There are still many people who are looking for SLR Camera. It’s because of the better function side. Some of photographers are dominant in using this kind of camera to take picture. If you are a photographer, you are recommended to read this following article. Well, let’s discuss it more.
            Single Lens Reflect (SLR) Camera is a camera which uses single lane lens lineup system to transfer the light into two objects, they are Focal Plane and Viewfinder, so it makes the photographer to see the object through the camera almost same as the resulting picture. It’s different with non-SLR camera, where the view which is seen in viewfinder can be different with the object which is caught on film, because this kind of camera uses dual lens lineup, 1 is to pass the light beam into the viewfinder, and another lens is to pass the light beam into the Focal Plane.
            SLR Camera uses Pentaprisma over the optical path through the lens onto the film strip. The incoming light then reflected upward by the mirror reflection and hits the Pentaprisma. Pentaprisma then reflects the light in several times until hits the viewfinder. When the button released, the glass opens the way for the light, so the light can hit the film directly.


Viewfinder
One of the important things in camera is viewfinder. There are two viewfinder’s system, they are:
·         Viewfinder window which is separated by the lens (Viewfinder type)
·         Viewfinder through the lens (Reflex type)

SLR Camera with the appropriate name (Single Lens Reflex), uses the second kind of viewfinder system. The eyes of the photographer fixed on the subject by the lens, so the ‘parallax’ will not happen. Parallax is the situation where the photographer can’t see the indication of the subject location accurately through the lens, so there will be a lost part when the picture is printed. This ‘parallax’ situation happens basically in photography which is very close up by using viewfinder camera.

Viewfinder Window

Lens
            In photography, lens serves to focus the light to be able to burn catcher medium (film). There are three rings outside the lens, they are focal length ring (for the variable lens), diaphragm ring, and focus ring.
Speed
            Shutter speed is a cover (to shut). When we push the button to take the picture, opening lens occurs, so the light enters and hits the film. Shutter’s job is to open and close it.
Diaphragm
            Diaphragm or aperture works to regulate the amount of entering light. This tool is usually behind the lens. Consists of 5-8 metal plates which are arranged and they can open wider and narrower.
Diaphragm numbers writing usually are f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16, etc. The smaller the aperture number, the wider the aperture resulting. So the entering light is more.

·         Large Aperture
Large aperture is used to produce sharp subject images with a blur background.

·         Small Aperture
Small aperture will produce sharp images from the foreground to background. Small aperture is usually used in landscape photography which needs the details and sharpness throughout the photo.

Depth of Field
            Depth of Field is the amount of range between the nearest subject and the farthest subject which appears in a sharp focus of a photo. For example, if we take the picture of the trees which are standing in a line, the printed picture will appear clearly for some of the trees in the front line and increasing blurred if they are getting back.

Exposure
            Exposure is the quantity of the light which is allowed to enter; the intensity (which is set by the lens) and duration (which set by the shutter speed) of the light which enter and hit the film.
