Setting the sensitivity (ISO) in digital imaging


In this article, at first with ISO sensitivity or in camera. Then about the sensitivity settings on digital cameras we will talk.


Setting the sensitivity (ISO) in digital imaging
Before you start talking about setting the sensitivity of this issue, we can that sensitivity in digital cameras to what means:


ISO (sensitivity)?
In the old traditional imaging, sensitivity to the meaning of the film‘s sensitivity to light ratio. This sensitivity was measured with the numbers (you probably have it for movies you seen photography  100, 200, 300, 400). Finding the number was lower,that film was also less sensitivity and aggregation photos that you are alsoshrinking.
In digital imaging, sensor sensitivity ISO image. The same law also photographed a film here is truefinding a lower number, the less light than your camera‘s sensitivityand the aggregation of small images.
The higher sensitivity settings are generally more in the dark conditions are used totake advantage of the higher shutter speed. For example, in a sporting event in terms of hermetically sealed when you want to see in low light with the proper resolution of the imaging setting used. Continue on the two pictures that are taken with a different sensitivity for instance. To the left of the photo sensitivity of 100 and 3200 sensitivity in the right of the photo is used. As it is visible, the amount of noise in the image to the right is much more.


The settings for sensitivity in photo shoot
ISO 100 sensitivity, usually as a fit and beautiful photos and crisp (with low noise) gives you.
A lot of people have digital cameras in your situation “Auto Mode” (automatic mode). This camera will vary depending on the conditions that you are taking pictures, selects the appropriate sensitivity (and try to make it as much as possible hold bottom), but most digital cameras, allowing you to make up that handy way sensitivity change also.
When you change your camera settings and a certain sensitivity you choose, you’ll see that to get a picture with the right exposure, Aperture and shutter speed you need to change as well.


Questions that you should consider sensitivity selection time
The settings for sensitivity in photo shoot
The time of the selection, it is necessary that these four questions in your mind:
1. light. Do you have a good exposure to the subject of your photography?
2. aggregation. Do I have a picture with coarse particle like, or prefer that my images without noise?
3. tripod. Do I use a tripod?
4. the moving subject. My subject is no moving or animated.


If the exposure is good, a little like the aggregation, we use a tripod, and I have no subject is moving, the ISO is better than a too low.
If the environment is dark vector images, aggregation and the noise you want, you don’t have a tripod, and/or your subject is moving, it may be better to increase thesensitivity of your camera, because it allows you to state that a higher speed for the shutter, and yet there is a good exposure in the photo.
Of course, increased sensitivity in this situation creates more noise in the photos.


The absence of higher sensitivity of the camera is justified

A series of circumstances that you may want to increase the sensitivity of your camera, read on:
Sports event in the environment . When your subject is moving rapidly and yet there you little light.
Concerts  that there is still a little light and the Flash cannot be used.
Art galleries, museums Most of the galleries have laws against the use of Flash and the hermetically sealed environment means a low amount of light.
Birthdays. Feet off the candles in a dark room, can be a very good memory of the controversial photo will give you that if you use the Flash will be corrupted. The morethe sensitivity can help you out of the scene photographed.


If you want more control on your digital camera, learn the sensitivity is one of the important aspects of digital imaging for you. Try different settings of today and its impact on your own images. Especially in the case of aperture and shutter speed are also get information, because these two items along with sensitivity, exposure triangle make up.
