Anatomy of a Camera

In principle, the camera is divided into three parts:
1. Lens
2. Camera body
3. Magazine / tape compartments

In principle, the lens is a lens like our eyes or the eye of the camera, for it's cleanliness and clarity should be on guard, because through lensalah image / light will be transmitted to the film or tape or digital. In cinematography we know there are three types of lenses are:

• Wide Lens: is a lens with a wide angle
• Normal lens: the lens that is considered to represent the perspective of the human eye to see the world and beyond. In the film, a normal lens is a 50mm lens.
• Tele Lens: is a lens with a narrow angle.

There is a lens that can take wide angles from the narrow lens like this is a lens with a variable focal length or more commonly called: Zoom lens. The weakness of the lens focal length is variable because the number of lens elements in it then there is the light theft caused by the refraction of light at each element of the lens.

At each lens professional and semi professional there are 3 pieces that the first ring is Focusing ring that serves to set the focus in a shot. Then there is the ring Focal length (in zoom lens or a variable focal length) is the length of the short focal length of a lens or technically known as the distance from the lens to the focal plane or film plane. The latter is F.stop ring or diaphragm that serves to adjust the exposure a shot.

Each lens has a flaw or weakness in each of their very nature and time of production, such as distortion, aberration, and others. Weakness or defect these lenses are not always considered bad because we can use to strengthen the dramatic effect that is in the scenario. As well as each lens has a sharpness of each region, the area is called the sharpness of depth of field shortened by DoF. So the depth of field is the area where the sharpness of the subject / object pins or blur in the camera.

Depth of Field itself is influenced by several factors including:
• The distance from the camera to the object or subject
Distance from the camera to the object or the subject will affect the long or short area because of the sharpness of an object or a subject close to the camera it will be the shorter depth of field on it because each lens has only one focal points.
• The size of the aperture diaphragm
The size of the aperture also affects the length of the short depth of field because the smaller the aperture diameter will become longer depth of field to mean the greater number such as 11 - 16-22 and so will the depth of fieldnya length, while the width of the diaphragm aperture diameter will be Short depth of fieldnya, meaning the smaller the number like 4 - 2.8 to 1.4 and so will the shorter the depth of field. Diafragama aperture is the diameter of the circle that also serves to regulate dark or bright a picture.
• The short length / focal length of a lens.
The longer a lens will affect the depth of field becomes shorter, while the shorter the lens will affect the depth of field to be long or wide.

Exposure and Scene Brightness

Exposure can be defined as the time required to record basic gambar.Fungsi a lens is to continue the light so that it can be used to print the image. Just as the phenomenon of pinhole or pinhole phenomenon means that if we remove the lens and replace it with black paper with a hole in the middle it will be well to capture the imagination only required exposure time will be longer.

Camera Body

In part this is an image recorded or captured both organically with celluloid 35mm film cameras as well as the change from light to electromagnetic waves on Video or Digital. In the film camera is the most important part of the contamination is kept dust, fluid or radiation because it will affect the shooting. In the video or digital camera in this section will be a lot of imagination settings button.
Magazine
In film cameras, the magazine is where we put the film both before and after exposure. In Video or Digital camera section is tape or card compartments, namely the part where we put cards like SD or CF or videotape.

Use cinematography as an art. Which we must always remember is that in order to achieve maximum results and satisfying, it takes considerable skill. A cinematographer should try to keep the camera to be foreign to him, we have to know every detail of the camera without having to think so that concentration can be used for the field of creative cinematography.
