Shutter Speed

Digital photography allows us to understand the world of photography, photographs resulted in a review can be directly through the LCD window, so we can evaluate the shots, because of technical data relating to catapult who had been seen and recorded, in contrast to conventional photography, where we have to print them first and can see , to review and evaluate the results jeperetan, any technical data it first we must note, that it took a lot of money and time wasted on who can improve our photography skills

Digital photography art can be described as painting with light, in this case the camera and lens that replaces the role of the brush and paint. There are two things that the most important role in the camera and lens, the Shutter Speed and Aperture

Shutter Speed is the length of time required to illuminate the CCD ato CMOS sensors on digital cameras, and film in conventional cameras. On the numbers listed Kemera 250,125,60,30,15 ff. This means that the duration of exposure is 1 / 250 sec, 1 / 125 sec, 1 / 60 seconds, and so on.

The larger numbers mean faster the time who used, this will create the effect of silent (freeze), for example, who we will be photographing a moving object, eg a car, with the effect of silence, we require at least a shutter speed above 1 / 125 second.

Conversely, if we will be photographing objects with moving effects, then the required shutter speed of less than 1 / 125 seconds, preferably done by following the direction of motion of the object, this technique called panning,

Two things also from the above depending on the speed of the moving object, the faster an object moves, it means that the higher the shutter speed required to obtain still or moving effects that we want, should be noted, the lower the shutter speed, will result in the greater also the possibility of camera shaking , who will cause shots to be rocking and not sharp.

To be safe, use a shutter speed above 30 or 1 / 30 seconds, if it wants a lower shutter speed, eg 1 / 15 sec, 1 / 8 seconds or undersell, use a buffer or use a tripod.


Aperture 

After discussing the Shutter Speed on the first section of this article, another element who are not less important in photography is to Aperture, Aperture is the size of the aperture that functions to enter and continue the light onto the film or sensor. size of regulated through the diaphragm. In general the camera contained 2.8; 4; 5.6 ff. angka2 is known as the f-number, so called aperture (aperture) f / 2.8, f / 4, f / 5.6 ff. The bigger the aperture the smaller the f-numbernya and the lesser diameter of opening, so it is smaller in diameter than f/16 f / 5.6

It works like a pupil aperture on the human eye, the more light coming in, the smaller the diameter of the pupil, and vice versa. Aperture very much associated with a sharp space or depth of field, the greater the f-number, eg f/22, sharpness will increasingly wide range. This means that objects behind and in front of the main focus has good sharpness. otherwise we will get blur effect / blur to objekdi front and behind the main focus when using a small f-number, eg f / 2.8

Shutter speed and aperture should be synergized to get proper exposure. ISO is also an important role, the higher the ISO is used, the sensitivity to light any bigger, so that at any dim lighting, shutter speed and aperture can still be used optimally. But keep in mind, the higher the ISO is used, the higher the level of noise or grain produced

To determine whether the exposure was correct or not, in conventional digital cameras available ato metering facilities. So that the occurrence of over-exposure (excess lighting), or under exposure (lack of lighting) can be minimized.

Once the basic technique can be mastered, the next is the flying hours required, because art is identical with the moment of photography, fine day and the moment was not easily repeated, skill determines the composition and angle of image capture can be developed as flying hours, then multiply references, books, internet, as well as other sumber2. How good and sophisticated a camera, just a tool, clincher is that those who were behind the camera
