Basic Photography Techniques

Basic Photography - Basic techniques of photography is something that must be mastered in order to produce good photos. Criteria for a good photograph is actually different for everyone, but there is a commonality of opinion that can be used as a reference. A good photograph has the sharpness of the image (focus) and lighting (exposure) is appropriate.

Basic Photography

A. Focus
Focusing is the sharpness of the object image set of activities, carried out by turning the focus ring on the lens so that objects seen in the viewfinder which was originally less clear it becomes clear (in focus). Photos said to be the focus when the object is sharp / clear and has a strict lines (not blurred). In the focus ring, there are numbers that indicate the distance (in meters or feet) object to the lens.

B. Exposure
The most important thing that must be considered in taking the picture is the lighting element. Lighting is the process of getting on camera dicahayainya film. In this case, the light received by the object should be enough so it can be captured on film. The process of lighting (exposure) involving some combination of things, the size of aperture, shutter speed and film sensitivity (ISO). These three things determine the success of photographers in getting the film tercahayai normal, ie the incoming light onto the film in accordance with the required objects, no excess light (over exposed) or lack of light (under exposed).

† ïƒ Aperture (apperture)
The diaphragm serves as a window on the lens which controls more or less light passes through the lens. The size of the aperture is denoted with f / numbers. These numbers are printed on the lens: 1.4; 2; 2.8, 4; 5.6; 8; 11; 16; 22; ff. Writing the diaphragm is f / 1.4 or f/22. These figures indicate the size of the aperture on the lens. Aperture diaphragm is used to determine the intensity of incoming light.

The relationship between numbers with the diaphragm aperture is inversely proportional.
"The larger the f / number, the smaller the aperture, so that light entering the less. Conversely, the smaller the f / number the more wide-aperture diaphragm so that light entering the lot."

Shutter speed (shutter speed)
Shutter speed is fast or slow shutter works opened and closed again. Long shutter speed control of light on film. How it works like a window shutter. Rana was in front of the field of film and is always closed when the shutter release is pressed, to protect the film from the light field. When the shutter release is pressed, the shutter opens and closes aka back so that light can enter and illuminate the film.

Basic Photography - The size of the shutter speed is calculated in units per second, namely: 1, 2, 4, 8, 15, 30, 60; 125; 250; 500; 1000; 2000; and B. . Numbers 1 means the shutter open with a speed of 1 / 1 sec. Numbers 2000 means the shutter open with a speed of 1 / 2000 second, and so on. B (Bulb) means the speed indefinitely (the shutter open as long as the shutter release is pressed)

The relationship between numbers by opening the shutter speed is directly proportional cover. "The bigger number means the faster the shutter opens and closes, the less light to enter. The lower it is, it means the slower the shutter opens and closes, the more light in."

Film sensitivity (ISO)
The smaller the unit of film (the lower the ISO), the film is less sensitive to light so more light is needed to illuminate the film, otherwise the higher the ISO the more light-sensitive film so that the less light needed to illuminate the film. For example, ASA 100 require more light than ASA 400, Basic Photography.
