When it comes to photographing, there are three major pillars and these three pillars are ISO, APERTURE, and SHUTTER SPEED. This trio work hand in hand and they have effects on images.
WHAT IS ISO
ISO is the light that comes into the image sensor. ISO is simply a camera setting that will brighten or darken a photo. When you increase your ISO, your photos will grow progressively brighter. For that reason, ISO can help you capture images in darker environments; making them look brighter. However, when it comes to using your ISO one needs to be very careful as it may have implications on your images. A photograph taken with high ISO will show a lot of grain, also known as noise, and might not be usable. You should only raise your ISO when you are unable to brighten the photo via shutter speed or aperture instead.
WHAT IS THE MEANING OF ISO
ISO means “International Organization for Standardization”. However, camera ISO does not directly refer to the organization that creates various technology and product standards. ISO initially defined only film sensitivity, it was later adopted by digital camera manufacturers with the purpose of maintaining similar brightness levels as film.
VALUES OF ISO
There are different values of ISO which range from:
- ISO 100 (low ISO)
- ISO 200
- ISO 400
- ISO 800
- ISO 1600
- ISO 3200
- ISO 6400 (high ISO)
HOW TO CHANGE YOUR ISO
There are different ways to change your ISO,and different cameras have different ways. Here are some common ways to change ISO:
- To start, enter a mode that lets you select the ISO yourself. Get out of Auto mode, and go to manual, shutter priority, aperture priority, or program (we tend to prefer Aperture Priority or Manual).
- For entry-level DSLRs and mirrorless cameras, you probably need to open a menu (possibly the “quick menu”) and find the section for ISO. Select the value you want, or set it to Auto.
- For higher-end cameras, there may be a dedicated “ISO” button on the camera. Press it while spinning one of the wheels to change your ISO setting. If you don’t see a button labeled “ISO”, it is still possible that your camera will let you program one to perform this task.
- Other cameras may have a dedicated wheel that already has various ISO settings marked. This makes things even easier.
