The Shutter and Aperture

All cameras have at least two ways to control light: the shutter and aperture. The aperture is like an iris in the eye, and controls light by changing size. When photographer takes a picture, the shutter opens briefly and the image is exposed.

In any shooting situation there are several combinations of shutter and aperture that could be considered correct. Which settings to choose is a matter of personal taste, and is usually influenced by how much light is available.

Image Stabilizer

Image Stabilizer is one of the excellent features offered by modern digital cameras. Stabilization will produce sharper images, because of the additional equipment that can reduce vibrations.

Each manufacturer has a different name for this stabilizer, for example Nikon with VR (Vibration Reduction), Canon with IS (Image Stabilization), or Sony with SSS (Super Steady Shoot). Technically there are two ways to reduce vibration.
(1) Stabilizer on the lens (optical), applied by Nikon, Canon, Panasonic
(2) Stabilizer mounted on the sensor (body), are implemented by Sony, Olympus, Pentax

Whichever system you choose, the existence of image stabilizer will be very useful because it is effective reduce vibration up to 2 or 3 f-stops lower. The following example of the effectiveness of damping you can see in the picture below:

 But that does not mean this feature may replace a tripod. Its effectiveness is based on my observations is 2-3 f-stops. So if you are able to hold the camera without vibration at shutter speed 1 / 30 s with no image stabilizer, means with the help of this feature, you will be able to shoot with a sharp in 1 / 15 or 1 / 8 s. But if you use a speed of 1 s, of course, will remain blurry image due to vibration.

For me, photography...

For me, photography is a very exciting field. Very unique. There are several aspects of photography that I think have similarities with the art of writing. Both are trying to do the recording of an event it's just using a different presentation formats. Which one to use verbal format and the other using a visual format.

 
Both are also capable of displaying events and conditions with a very good opinion even though the lift of a situation that sometimes appear normal, as long as the situation would aimed by with the right angle.
 

For me photography has become one of the activities of a hobby. There is a certain satisfaction from each of the resulting shots. I also hope that one day this hobby can continue to be a professional activity like any hobby in which I live to teach professionally as a lecturer.
