Have you heard the ISO? In photography there are important settings to look at, and one of these is what we called the ISO but what is ISO on a camera? To quick understand the ISO, this is the light and dark in your image adjustment in your camera. If you want to increase the number of ISO, the image will bright when you take a picture from your camera, and if you decrease the number of your ISO it will dark your image from your camera and can be analize in your lcd screen. See how the difference when adjust these settings.

Increase ISO

You can use to increase the ISO when your surroundings becoming dark or in night shot or inside your house. You will see that result. By pressing your left thumb the ISO will appear in your LCD screen, and dial moving to the right from your right thumb in the upper portion of camera shoulder.

You can start your ISO speed from 100 to 1600 ISO or more. Below you can see the advance setting if you go to higher or lower numbers and results to darker or lighter.

ISO in Wikipedia

A system for quantifying the sensitivity (“speed“) of a photographic emulsion, or a solid-state digital-camera’s image sensor, to visible light. Normally followed by a numerical value, e.g.: ISO 100 or ISO 64/19°. Developed from the ASA and the DIN systems by the International Organization for Standardization.

Looking ISO

Decrease ISO

To decrease the ISO when you are in bright surrounding area, the bright outside is enough to enter the amount of light to your lens going to the sensor image.

Middle ISO

I use middle ISO when I’m going to take shot with cloud outside and subject is wild birds, and I make apply more ISO if I’m not satisfy by the light in the image.

  • ISO 400
  • ISO 800

You can start from 400 ISO to see the image result after shooting in cloudy sky and your shutter speed 125s, 200s, 250s to 500s. Try increase or decrease until you like the picture.

Practice ISO Shooting

The best is to practice your ISO settings and make shots even hundreds of times until you understand and balance the light for your image that looks better or beautiful enough. That your own eyes will love the Image you took a picture.

Understanding ISO to shutter and aperture

You know, you can’t produce images without this two they shutter and the aperture. You see above a triangle? That is the exposure triangle, soon you will understand how to use this in dslr camera, you have to remember that you control the settings not over exposed or under exposed. Aperture and shutter speed are the companion of this ISO, just like you have a coffee with 3 in one to make great taste experience you have to control not over or not under exposure.
