With Auto ISO, Your Photos Are More Sharp At Any Time

Say you are traveling or walking while carrying a camera, while unexpected will always appear a very good moment to be photographed. Moments like this take a moment and will not happen again. When you see the moment and immediately take pictures to not lose the moment, there is a possibility that the image you produce will blur or blur.


Why blur? Many reasons, one of which is because the moment occurs in areas that are not perfect light conditions so that our shutter speed is slow, say 1/60 sec. With a shutter speed like this while we are shooting not under direct sunlight, guaranteed your photo will be a little blur. How's the trick?

To avoid it, the trick is to activate the Auto ISO feature on the camera. (If you are confused about how to increase the ISO can increase the shutter speed, read the concept of exposure and read the ISO concept for beginners) With Auto ISO setting: ON, the camera will automatically raise the ISO when the camera shutter speed becomes slow. When Auto ISO is active, we can even determine the minimum shutter speed limit and also determine the maximum ISO. So as if we ordered the camera: "Hey camera, so shutter speed under 1/125 seconds, raise the ISO, but not too high huh! Maximum 3200 ISO only !! "

How to Activate Auto ISO?

Canon DSLR cameras, push and hold the +/- ISO button, then rotate the main dial until it says A (Auto) on the upper LCD screen, then select 1/125 seconds as the minimum shutter speed.

Nikon DSLR cameras, go to Shooting Menu, then ISO Sensitivity, select ISO Sensitivity Auto Control, select ON, then select 1/125 as minimum shutter speed then click OK. 

What is the Safe Maximum Limit of ISO?

The answer depends on your camera, occasionally test the noise produced by the camera when you use a high ISO, eg 3200 or 1600. If at ISO 3200 you are still okay with the noise it uses only 3200 for the maximum ISO limit. Also depending on priority, what would you like, a blurry photo or a photo with noise?
