Basic Photography Techniques

Basic Photography Techniques

Basic techniques of photography is something that must be mastered in order to produce good photos. Criteria for a good photo is actually different for each person, but there is a common opinion that can be used as a reference. The images have good image sharpness (focus) and lighting (exposure) is appropriate.
A. FOCUSFocusing is the object image sharpness set of activities, carried out by rotating the focus ring on the lens so that it looks in the viewfinder that the original object is less clear it became clear (in focus). Photo said to be the focus when the object is sharp / clear and has a firm lines (not blurred). In the focus ring, there are numbers that indicate the distance (in meters or feet) object to the lens.


B. ExposureThe 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 should be enough so that objects can be captured on film. The process of lighting (exposure) involves a combination of several things, namely aperture size, shutter speed and sensitivity of the film (ISO). Three things determine the success of the photographers in getting the film normal tercahayai, the light entering the film in accordance with the required object, not the excess of light (over exposed) or lack of light (under exposed).
 Aperture (apperture)The diaphragm serves as a window on the lens that controls the bit or the amount of light passing through the lens. The size of the aperture diaphragm is denoted by f / numbers. These numbers are listed on the lens: 1.4; 2; 2.8, 4; 5.6; 8; 11; 16; 22; ff. Writing of the diaphragm is f / 1.4 or f/22. These figures show the size of the aperture diaphragm in the lens. Aperture diaphragm is used to determine the intensity of incoming light.
The relationship between the numbers with the diaphragm aperture is inversely proportional."The larger the f / number, the smaller the aperture, so that light entering the less. In contrast, the smaller the f / number the wider aperture diaphragm so that light entering the lot."
Shutter speed (shutter speed)Shutter speed is fast or slow shutter opens and then closes back to work. Shutter speed controls the length of light on film. How it works like a window shutter. Shutter in front of the film plane and is always closed when the shutter release is pressed, to protect the film plane of the light. When the shutter release is pressed, the shutter opens and closes aka back so that light can enter and illuminate the film.Aperture size is calculated in units per second, namely: 1, 2, 4; 8, 15, 30, 60; 125; 250; 500; 1000; 2000; and B. . Number 1 means the shutter open with a speed of 1/1 sec. The figure 2000 means the shutter open with the speed of 1/2000 second, and so on. B (Bulb) mean speed indefinitely (the shutter open as long as the shutter release is pressed)
The relationship between numbers by closing the aperture opening is directly proportional. "The greater the number means the faster the shutter opens and closes, the less light to enter. The lower it is, then the slower the shutter opens and closes, the more light in."
Film sensitivity (ISO)The smaller the unit of the film (the lower the ISO), the film is less sensitive to light so more light required to illuminate the film, otherwise the higher the ISO the more light-sensitive films, so the less light needed to illuminate the film. For example, ASA 100 requires more light than ASA 400.
