Be A Better Photographer: ISO Settings

Part of my journey to become a better photographer is to teach myself starting with the basics. I learnt about photography almost backwards. Learning to edit before really getting into the actual photo taking. Read through my notes and see my practice shots while I try to become a better photographer.

ISO Settings:

What is it?

The ISO sets the amount of light needed for good exposure by calibrating how sensitive the digital image sensor is to the light. It is measured in a simple numeric system usually starting with 100 and (depending on your camera) may go up to 3200.

How to set it?

Every time you double the ISO value (ie. from 200 to 400) the camera needs half as much light to create a well exposed photo. The lower the number you have the less sensitive your digital sensor is; thus requiring a nice bright situation. Likewise, the higher the ISO value the more sensitive your sensor is which means more light will be translated to your photo’s.

When to adjust it?

Use a low ISO setting in nice bright situations like being outdoors. Use a higher ISO when you are indoors or at night.

Cranking the ISO will create more noise in your end result. Luckily grainy pictures are all the rage right now!

Hopefully this quick overview of ISO basics will help you be able to control your DSLR a little bit better. Personally, I find I don’t usually have to adjust it very often and prefer to focus more on aperture and shutter speeds (which I will have posts on in the future).

Here is a few more other helpful sites on ISO. Here and Here.

**This is only my conclusion based on my own research and practices. Everyone has their own processes.**
