Understanding the concept of ISO, Aperture and Shutter speed.


In the world of photography there are three basic things that we must understand in advance, so that if we use it then we do not get confused and certainly do not want unwanted events occur. From the 3rd thing is the importance of understanding and using ISO, diaphragm and shutter speed.
We are going to review all of them here.


ISO
ISO
ISO Table

In terms of ISO or ASA is the level of the camera sensor sensitivity to light. So the greater the value of the ISO setting on camera, the greater or much light will be obtained, and vice versa.
To produce good photos, not over or under exposure then we must master the three basic settings. To master these three things it needs a lot of exercise so that by itself feeling we will be honed to be able to set up the camera to exactly fit the conditions of the object that we face and the image that we expect.with lots of shooting we would get used to and adapt to the light.To get maximum results, we must feel, observe and enjoy the atmosphere around us. Yes, photography is not arbitrary in taking a photograph. By feeling we can know when it is time we take a photograph.
  • Just as we will be photographing an object during the day then for a good ISO setting is between 100-200.
  • For setting the cloudy atmosphere we can take the ISO in figures 400-800.
  • For shooting inside the room we can set the ISO diangka 16,000 to 3200.
  • And for taking pictures at night of course, we need light yaang not least, for a perfect figure is 6400+.
Shutter Speed

Shutter speed

Its function is set faster than the shutter open so as to pass a beam of light that fit with the needs of the conditions at that time.If we see the selectors listed number B 1 2 4 8 15 30 60 125 500 1000 2000 The figure also illustrates the scale fractions of seconds, so for example, 1/60 the speed chosen numbers opens the shutter speed is 1/60 sec.While the letter B in front of figure 1 it is a sign that the shutter will be open continuously as long as the shutter release button is still our press, or open the shutter function in accordance with the time we need.B speed selector function is used for example, we want pictures of objects in the form of billboard lights in the evening or night atmosphere.Selection numbers kecapatan open the shutter depends on the situation / condition of the object that we wish to photograph.To capture / freeze moving objects such as a car or a motorcycle that was speeding then we choose a high speed katakankah 500 upwards. Conversely, if you want to produce the effect of moving objects, then we choose a slow speed at the time we shoot a moving object such. Speed ??can be chosen from 30 down.With the selection of the slow speed when our focus is directed at moving objects, the background that appears in the photo is clearly visible while the object is visible blur / motion. Of course the selection is adjusted to the speed of the size of the aperture that we choose well, in order to burn the movie to shoot right.

Aperture
Aperture
Aperture
Aperure is one component in a manual camera that functions as a regulator of the size of the lens opening.In manual camera function regulator Aperure is located on the circular rings on the lens.Symbols used is f. If we perhatikaan around the bracelet stamped figure of 1.4 2 2.8 4 5.6 8 11 16 22 the figure is actually a fractional number that describes the ratio between the size of the light intensity on the outside of the camera with the intensity of light in the lens, Thus, for example, f / 1 as the biggest opening of a lens, it means that the intensity of light outside and inside the lens is the same.

We take f / 1 earlier as the biggest opening of a lens is then further openings is half of its previous strength. Retrieved 1 / 1.4 = 1.4 and 1,4x1,4 = 1,96 which is then rounded up to f / 2 and then successively obtained f / 2.8 -11 and -8 -4-5,6 onwards. Because each stop difference is half or half of the numbers left and right, then we can easily find that at f / 4 light entering adaalah 1 / 2x1 / 2x1 / 2x1 / 2 = 1/16 and at f / 8 is 1 / 2x1 / 2x1 / 2x1 / 2x1 / 2x1 / 2 = 1/64 because the numbers listed in
Aperure bracelet is actually a fractional number. Thus, the small figures show the largest diaafragma openings, while large numbers show a small aperture.
