The basic techniques of photography

The basic techniques of photography is a matter that must be mastered in order to produce a good photo. Criteria for a good photo is actually different for each person, but there is a similarity of opinion that can be used as a reference. A good photograph has the sharpness of the image (focus) and lighting (exposure) is appropriate.
A. FOCUSFocusing is set sharpness of the object image, done by turning the focus ring on the lens so it looks in the viewfinder that the original object is less clear it becomes clear (in focus). Photos said to focus if the object looks sharp / clear and has a strict lines (not blurry). In the focus ring, there are numbers that indicate the distance (in meters or feet), the object with the lens.
B. ExposureThe most important thing that must be considered in taking the picture is the lighting element. Lighting is the existing process dikamera dicahayainya film. In this case, the received light enough so that the object must be recorded on film. The process of lighting (exposure) involves a mix a few things, namely the diaphragm aperture, shutter speed and film sensitivity (ISO). The three things that determine success in getting the film photographer who tercahayai normal, that is the light that entered the film in accordance with the required objects, no excess light (over exposed) or lack of light (under exposed).
 Aperture (apperture)The diaphragm serves as a window on the lens that controls more or less light through the lens. The size of the aperture diaphragm is denoted by f / number. These figures are listed 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 diaphragm on the lens. Aperture diaphragm is used to determine the intensity of incoming light.
The relationship between numbers with aperture diaphragm is inversely proportional."The bigger f / number, the smaller the aperture diaphragm, so that light entering the less. Conversely, the smaller the f / number the more wide-aperture diaphragm so that light entering more and more."
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.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. . Number 1 means the shutter open with a speed of 1 / 1 sec. Figures for 2000 means the shutter open with a speed of 1 / 2000 second, and so on. B (Bulb) means no time limit speed (shutter open as long as shutter release is pressed)
The relationship between the numbers with the shutter speed is directly proportional to open shut. "The bigger the number means the faster the shutter opens and closes, the less light entering. The smaller the number, it means that 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 requires more light than ASA 400.
