Iso, Aperture and Shutter Speed Triangle

Iso, Aperture and Shutter Speed Triangle

Hey everybody today we going to talk about exposure what it is and how to work with it plus what exposure compensation on your camera is.


What is Exposure:

The exposure is actually an Iso, Aperture and shutter speed triangle also known as exposure triangle. All these elements played out together are the exposure.


How to use it:

Many photographers make a big fuzz about it and seem to over-complicate the whole topic. So to make it quick and easy always keep in mind that if you change one of the three elements from the exposure triangle, it will make your picture brighter or darker plus it will change the element’s attribute. For example, when you turn up the iso it will not only make your picture brighter it will also give more grain to the picture.

Super smart quick explanation. 🙂

  • Shutter speed: If you use a shorter shutter speed the exposure will become darker but also movements will be frozen. The other way around would be a brighter exposure and fast movements will get blurred.
  • Aperture: If you close your aperture (higher number) the exposure will become darker but the depth of field will be very wide. The opposite way would be a brighter exposure and a narrow depth of field.
  • Iso: A low Iso will make you a wonderful grain free image but a darker exposure. If you turn it up the exposure will be way brighter but the grain will increase as well.

 

In case you did not completely understand it here is a link you a digital online camera to try it out.


Quick Tips:

 

  1. When you use your camera in the Av or Tv mode (aperture priority or shutter priority) you only have to choose your aperture or shutter speed and the camera will adjust your exposure. (iso will not change)
  2. Use your exposure compensation. To do that (on an entry level Canon DSLR) you need to press and hold the Av button on the back then roll the wheel. If you turn to the right you picture will become brighter depending on how many f/stops you turn it up. To the left, it will get darker. But now comes the clue when you use Av or Tv your dialed in aperture or shutter will stay the same and the camera will adapt to it just 1 or whatever you dialed in f/stops darker or higher.

That’s already it I hope it was easier to understand than it was for me to write it 🙂 If you have any questions or opinions let me know in the comments 🙂

    I love it! I’ve been looking to get into photography as a hobby and having trouble knowing where to begin. Seems like I landed in the right spot. I have a camera but still learning how to use it. This is pretty interesting, the whole exposure triangle thing. I’ve heard of it but didn’t quite understand it. Thanks for making it so simple. Keep the tips coming!
