What Is ISO?

ISO is a number that represents how sensitive your camera sensor is to light. ​Also controls the amount of light your camera lets in, and therefore how dark or light your photos will be. ISO stands for International Organization for Standardization.

How Does It Affect Your Camera?

Controls the amount of light your camera will let in, and therefore your photos will be light or dark.

What does a low/high ISO mean?

A lower ISO value means less sensitivity to light, and the more light you will need to take the photo. While a higher ISO means more sensitivity, and the less light you need to take a picture.​It’s one of the element in the photography’s exposure triangle — along with aperture and shutter speed — and plays an important role in the quality of your photos.

If you use a High ISO  it can  degraded image quality and cause your photos to be grainy or “noisy.”​

High VS Low ISO

It’s good to be on a low ISO to avoid noise and a degrading quality in the image.

Low Light Situations

In low light situations, it is often crucial to raise the ISO in order to get a clear picture. The huge problem with raising the ISO, though, is that it introduces ‘noise’ into the image , which can make it appear grainy.​

If you are taking a picture in excellent light conditions, you will want to keep the ISO low in order to dodge introducing noise into the image.

How to Adjust ISO On A Camera

To adjust ISO on the camera you will need to press the ISO button and will you need to use the swivel at the top to rotate it so it will go into a lower ISO or a higher ISO.

Edward Weston

Edward Henry Weston was an American photographer. He has been called “one of the most inventive and dominant American photographers” and “one of the masters of 20th century photography.” Weston was inventive due to the types of photos he would take. Weston was born in March 24th 1886 and died  January 1, 1958. He was 71 years old.

My work of High ISO VS low ISO

High ISO Photos

Above is the information of the photo that has been taken at a high ISO. The ISO was set to 6400, it was set to this so I could achieve a grainy and degrading effect to show the difference between a High ISO an A Low ISO.

Another High ISO Photo

Above is the information of the photo that was taken at a High ISO. The ISO was set too 6400 it was set to this so I could achieve a noisy and grainy effect, like it is above.

Low ISO Photos

Above is the information of a photo taken at a Low ISO. The ISO was set to 200 it was set like this to achieve a clear picture that you can see properly without lots of noise produced.

Another Low ISO Photo

Above is the information about the photo that was taken at a Low ISO. The ISO was set too 200 to achieve a crystal clear image that is easy to see rather than being made with a degrading quality.
