The art of photography is constantly evolving and attracting new workers under its cover.
If you want to learn how to make beautiful pictures, you definitely need to know what is an excerpt from the camera.
What role does the excerpt?
Before the shot will go to the memory card,something has to happen in the lens and in the camera as a whole. You may have noticed that the pictures obtained by varying the brightness and with varying amounts of light and shadows. These visual effects are directly dependent on how much light will pass the lens cap on the matrix.
In disclosing the bolt rests on twoparameter setting: the aperture and, indeed, endurance. The latter is responsible for the amount of time that will pass before the lens shutter is closed. It is measured in seconds. Since only one shutter speed does not determine the result of the image, without the diaphragm is difficult to explain the value of this mechanism. Aperture - a bulkhead itself, which depending on the settings changes its diameter, thus controlling the amount of light on the sensor.
How to use restraint
Shutter speed is adjusted depending on the ideas andthe conditions under which the photo is removed. If the room or on the street is too dark, you should put a very slow shutter speed. Over time, that will be exhibited in the settings of the camera, a sufficient amount of light gets into the camera. This amount and takes a photo with a saturated, bright and deep.
The main problem of long exposure thatmove the camera while it is impossible to shoot. Even the slightest failure would lead to an unclear image. Therefore, in its work to use a slower shutter speed, you need to buy a tripod, which will still be recorded on the camera.
If image depth is not as important, and most importantly -in time to catch the frame, it is necessary to use a fast shutter speed. The word "short" means 1/40 of a second or less. If the picture needs to be done in a dark room, you will have to adjust the speed and aperture.
Any automatic mode on the camera is notIt will give you the possibility to adjust the shutter speed as you want. Therefore, there is a professional SLR "shutter priority" mode, which is indicated by the letters S or Tv. This means that you can manually set only desired option, and Aperture will adjust automatically.
Also, on most SLR cameraspresent M mode, or a "manual". Once selected, you can also control the speed. But in addition to her you will need to independently monitor and behind the diaphragm. Since the parameters have to adjust at the slightest change of light, photographers rarely use this mode.
