Understanding The Exposure Triangle

May 6, 2019

What is it?

The exposure triangle is the backbone of photography. It is what will help your images look how you want them to. It keeps things sharp and in focus, adds movement and blur, adjusts the level of brightness and more!

In the past, I have shared photography tips and tricks. Things that I learned when I first started out and felt overwhelmed. So today, I want to take some of those things and bring it to together. We are going to do that with the exposure triangle.

The exposure triangle is just that, a triangle. Three sides! Aperture, shutter speed and ISO. And those three things come together to expose your photo.

So, if you haven’t already, learn about aperture. Then learn about shutter speed. Then ISO. Figure out what each of them does, how they change the look of your images and what they will do when you adjust them.

Now, the exposure triangle is just bringing those three things together. If you set your aperture, your shutter speed and your ISO but your photo is too dark.. you have options! Edit it later (I hate editing.. we’ve gone over this!). Or, change it in camera. If you’re like me and want to change it in camera, well then you still have options!

  • You can open your aperture more, which means taking it to a lower F stop number. This can change the focus depth though. So if you don’t want to change that, leave it alone.
  • You can slow down your shutter speed. This can allow more time to let light into your camera sensor and brighten the image, but it can also cause blur or softness in your photos if it is too slow and your subject is moving or you don’t have a tripod.
  • The other option is to raise your ISO. Depending on your gear and camera capabilities, this can add some noise and grain to the image.

With all these options, it can be intimidating or overwhelming. You have to know what each side of the exposure triangle does, what your personal priorities are when shooting and what your gear is capable of! So do your research, practice, practice and then practice some more.

But once you nail the exposure triangle, you can shoot in manual all the time! You get to be in control of your camera and not the other way around. If you want to learn more about how to do that, check out my photography course. I think it will answer all your questions!
