When you refer to the camera settings whether it is on a digital camera or a camera, you will find a setting with the ISO name. Not many understand the meaning of the word primarily its function. And knowing the basic info can be used it for the art of photography to qualify the image result
For those of you who still use the camera in regular mode, then you need to know the ISO capability and use it. By knowing about the term, you can later improve the results of photography. It means that you can get the higher level in this photo’s world.
Do you have problems with light adjustment techniques when shooting? If so, you need the basic concept of ISO to improve your image. Yes, this camera feature is one camera feature that is closely related to lighting. One unique result is still bright and very charming if you are shooting in a room that is minimal light or dark.
To help you understand this exciting feature, we have summarized a basic understanding of the features that can make your image brighter.
ISO on photography is an indication of the level of camera sensitivity to light. You can open your camera and will find this feature in the settings menu. With these feature settings, you can choose the right ISO scale according to the lighting conditions around you. You can find the explanation of this scale in the picture below.
This feature becomes one of the necessary elements of the Photography Triangle or Exposure Triangle. Along with the aperture and shutter speed, it will be able to change the image to be more brilliant. And when you are learning this element, you may also need to know some basic of the two others. Knowing them three, even the basic will make you entirely in a higher level of photography skill.
For those of you who already know a lot about exposure, maybe you agree if this element is an important thing to note for photographers who want to make the picture becomes bright.
This element has its own size with different levels of brightness.
Levels of ISO
Levels of exposure elements are very numerous and are usually written with numbers such as 100, 200, even up to 25600. The key is that the higher the value it means, the higher the level of lighting sensitivity that will be done by the camera. That is, the picture you take becomes brighter than the lower level.
With this amazing ability, it enables its users to maximize camera shots in any circumstances. Whether in bright or low light conditions, you can use it and adjust the scale settings for best results.
Do you still not understand the basic concept of this ISO element? Because it is a bit complicated, then the easy discussion is to use the parable. The parable to be used is the bee parable.
The parable is simple, try to suppose that an ISO is a worker bee. If you set the camera and scale it to 100, then that means there will be as many as 100 worker bees ready to help you. If you set it on a scale of 200, then supposing that you now have 200 worker bees.
Suppose bees have the task of picking up light coming through the camera lens and producing the brightness in the image. Now, with this simple parable, you can try to analyze a question. The question is which image is quickly finished and produces a brighter light between the 100 and 200 scales? Try to practice and get the answer to this question.
With the same aperture, then of course shooting with a larger scale will be faster and produce a brighter image. Even with such imagery, there are several things can be taken as an outline for further elaboration. If you have done to analyze it, try to compare with the result below
Outline of ISO
There are at least three things that can be obtained if you practice the above parable when you use the camera. Note that it is the normal camera and use the same model and settings to practice both. There is no modification to practice it.
The first thing to get is a conclusion that the addition of the ISO scale can shorten the time required to take a photo. Even more interesting about this is the short time to reach half or two times faster.
There is a particular note on this first result. That is, in the experiment the aperture is the same on a scale of f3.5. You will also find the same answer if using aperture priority (in symbol A or Av). Shutter speed is from 1/125 to 1/250 seconds. Of course, this is enough to prove that the higher the ISO scale, the faster the shooting.
The second thing is if you turn it into a 400 scale, then you will shorten the time doubled again. On this scale, you will get a speed of 1/500.
With both lines above, it can be concluded as the third outline. The last outline is that each time it shortens the exposure time by half; it means that you raise the exposure by one stop. If you think you need to prove it more, you can practice more and try to use different ISO scale. In a normal camera such as in smartphone, there are more than four scale choices.
Now, you can try to experiment on your own. Since this is very much related to exposure, then you can try changing some other elements to try it out. The more you try and practice, the more you will understand about this element.
By comparing the results of each shoot, you can tell the primary difference. You can also try it with an aperture that you may increase or subtract. You can also change or set shutter speed so that the ISO experiments are colorful.
