Basic Photography Techniques

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 common ground that can be used as a reference . Photos have a good image sharpness ( focus ) and lighting ( exposure ) right .

A. FOCUS

Focusing is the object image sharpness set of activities , carried out by turning the focus ring on the lens so that the object seen in the viewfinder initially less clear it became clear ( in focus) . Photos said to be the focus when the object looks sharp / clear and has lines that firm ( not blurred ) . In the focus ring , there are numbers that indicate the distance ( in meters or feet ) with the object lens .

B. exposure

The most important thing to consider in doing a photo shoot is a lighting element . Lighting is an existing movie dicahayainya process on camera . In this case , the light should be enough so that objects can be captured on film . The process of lighting (exposure ) involves a blend of a few things , namely the size of aperture , shutter speed and film sensitivity ( ISO ) . Those three things determine the success of a photographer in the film tercahayai get normal , ie light entering the film in accordance with the required object , not excess light ( over exposed ) or light deprivation ( under exposed ) .

Aperture Diaphragm ( apperture )

The diaphragm serves as a window on the lens that controls the amount of light passing through little or lens . The large size aperture is denoted by f / number . These numbers are printed on the lens : 1.4 , 2, 2.8, 4 ; 5.6 ; 8 ; 11 ; 16 ; 22 ; ff . Writing diaphragm is f / 1.4 or f/22 . The figures indicate the size of the aperture on the lens . Aperture is used to determine the intensity of incoming light .

The relationship between the rate is inversely proportional to the aperture .

" The larger the f / number , the smaller the aperture , so that light entering the less . Conversely , the smaller the f / number the wider the aperture diaphragm so that light entering more and more . "

Shutter speed ( shutter speed )

Shutter speed is fast or slow shutter opens then closes back to work . Long shutter speed control light on the film . How it works is like a window shutter . Rana was in front of the film plane and is always closed when the shutter release is not suppressed , to protect the film from light fields . 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 , ie : 1 , 2, 4 ; 8 ; 15 , 30 , 60 ; 125 ; 250 ; 500 ; 1000; 2000; , and B. . Figures 1 means the shutter open with speed 1/1 sec . Numbers 2000 means the shutter open with a speed of 1/2000 second , and so on . B ( Bulb ) mean speed indefinitely ( shutter open as long as the shutter release is pressed )

The relationship between the aperture opening rate is directly proportional closes . " The bigger the number means the faster the shutter opens and closes , the less light that enters . The lower it is , means the slower the shutter opens and closes , the more light in."

The film sensitivity ( ISO )

The smaller the unit of the film ( lower ISO ) , the movie is less sensitive to light so that more light is needed to illuminate the film, otherwise the higher the ISO the more sensitive the film light so the less light is needed to illuminate the film. For example , ASA 100 requires more light than ASA 400 .
