Technical Photography & Functions

Evel small

Photography is not everything about the camera. It is said that photography is the art of playing with light. In the absence of light, then it is impossible photography. Produces a good picture, must have a strong vision in terms of 'look'. Noting the light, composition and moment are the things that are important to consider in making images that can be categorized as 'good'.
However, it seems impossible to produce a photo like that if you do not know and understand the respective technical basic photography. Photography is not everything about the camera, but the camera is a tool to deliver our vision. So, if need to know and understand how a camera works.
The main task of the camera is set the intensity of incoming light and in the end of the film / sensor (hereafter I call medium). If, cameras allow too much light entering the medium would be burned (overexposed). And vice versa. How to light coming in was not excessive and no less, or in other words 'fit'. Here I describe one-one.
Aperture Or is often called the diaphragm or aperture lens is used to regulate how much the lens opens. This function is more precisely located on the lens. Logically, the larger the opening, the more light will enter. Like a water faucet. The bigger we open the faucet, it will more and more water will come out.
Writing the correct Aperture is f / x. So when it is said his Aperture value is 5.6, then the correct writing is f/5.6. So do not be confused when someone said that the 2.8 aperture lens aperture greater than 5.6. Because if you are writing is true mathematical khan? (F/2.8> f/5.6), but most of us are lazy to say f/2.8 or f/5.6, because we are simple people still ...
Side Effects of Aperture As a cough medicine that has side effects, as well as the aperture. The side effects are greater the aperture lens, it will be smaller regional focus. And vice versa. This focus area commonly known as the DOF (Depth of Field).
Shutter Speed Or commonly referred to as speed or shutter speed on duty to regulate how long the mirror open and closed again to limit how much light will enter. Like the faucet theory, if we open the tap too long, then the container was going to excess water reservoir so that it will meleber out. If in the case of photography, the medium will burn.
Writing the correct shutter speed is 1 / x. So when it is said that a photo menggunkanan speed 60, then writing the correct is 1 / 60 sec. So do not be confused if you say that speed 60 faster than 30. because the writing is so mathematically khan?
Side Effect of Shutter Speed Like the dating that has side effects, such as hard glance woman / other man, as well as shutter speed. The faster the shutter speed, it will be increasingly seen silent picture (freeze). And conversely, if the speed is too slow image will look blurry because of movement is too fast, so that the object seen moving very fast.

ISO or ASA Is the sensitivity of the medium in the light. The higher the value, the more levels of sensitivity. That is, if we change the ISO or ASA value becomes higher, while the aperture and speednya not changed, then the medium will receive more light. And vice versa.
Side Effects of ISO or ASA ISO is the sensitivity of the sensor (medium), while the ASA is the sensitivity of the film (medium), so the difference is only dimediumnya only. But the same logic. Except for side effects. Where in the use of high ASA film, the picture will look grainy (in the form of small point but many). While the use of high ISO will generate noise (such as a worm but a lot). Little problem, let alone a lot already amused =)
