Camera Basics: The Photography Triangle

You might have heard of the golden triangle in photography – a guideline to capture a good photo that is exposed correctly and applicable for both digital photography and film photography. The 3 critical aspects/elements are Shutter Speed, Aperture, and ISO. All these three settings are so important to balance out the exposure on your image and ensure a sharp, aesthetically pleasant image with proper brightness (how dark or light the image is). So if you change one setting, it will affect the other two settings as they are connected. And the only way to get a perfect exposure value is to balance out the three settings. Here’s what a Photography Triangle looks like.

What is Exposure?

Exposure is an important factor yet fundamental in photography terms. Exposure simply means the amount of light entering the camera sensors and capturing the visual image. But to get proper exposure, there’s a need to balance the 3 settings mentioned above so that the image is not overexposed yet underexposed. Overexposed refers to images that are brighter with almost white to no detail while underexposed refers to images that are darker. We often forget that camera doesn’t work the same as our eyes where our eyes are adapted to pick up small details of brighter and darker areas.

Too bright = overexposed

Too dark = underexposed

When shooting outdoor especially, our eyes are slowly adjusted to the sunlight that is often letting too much exposure to our cameras. And at which we have to manually adjust it to make it dimmer/not harsh to the eyes. Keep the photography triangle in mind!

  1. Narrow your aperture: Using a higher f/stop that gives lesser exposure = a darker image
  2. Using a faster shutter speed: Using a fast shutter gives shorter exposure to light = a dark and sharper image
  3. Lowering your ISO value: the lower the ISO, the lesser sensitive the camera sensor becomes = and the darker the photos appear

How to fix an underexposed image?

  1. Widening your aperture: Using a lower f/stop that gives more exposure = a brighter image
  2. Using a slow shutter speed: Using a slower shutter speed gives longer exposure to light = a brighter image
  3. Increasing your ISO value: the higher the ISO, the more sensitive the camera sensor becomes = brighter and grainier the photos appear

Nowadays, cameras have pre-existing settings aperture priority, shutter priority, and auto-mode settings/features where it will automatically preset and adjust to a suitable exposure. But, you can also shoot in manual mode, where settings are fully controlled manually by yourself which allows more creativity in playing with the light and understanding the whole concept of the photography triangle. Other than that, there are also options for editing in the post-production phase. Use Adobe Photoshop Lightroom exposure slider to adjust the exposure and editing software like Adobe Premiere Pro/DaVinci to manually brighten/darken the exposure.

Lastly, constant practice is the best way to improve in getting the right exposure and get better. Taking pictures in variable shutter speeds, and lighting conditions as well as playing with the photography triangle will help you learn to use it in various settings.
