Every photographer should know the fundamentals of leveraging shutter speed, aperture and ISO to control the exposure levels of your photos.
In this article, we discuss the various nuances of aperture, shutter speed, and ISO settings so you can shoot effectively and create stunning pictures.

How do aperture, shutter speed, and ISO work together in photography?
Aperture, shutter speed, and ISO settings are used to control the exposure levels of your photos. Below are the key differences of each setting below:
Aperture
Aperture is the size of the opening in the lens when a picture is taken. A large aperture (the number will be low) results in less light coming in but a shallow depth of field. This is great for portraits where you want the subject in focus but the background blurred. A small aperture (the number will be high), on the other hand, lets in more light but gives you a deep depth of field making everything appear in focus. This setting is ideal for landscape photography.
ISO settings refer to the sensitivity of your camera sensor. A low ISO setting (100-200) results in less noise or grain in your photos but it also means you need more light to take a picture. A high ISO setting (800-1600) means that you can take pictures in low light conditions but there will be more noise or grain in your photos.
How can I use aperture, shutter speed, and ISO to create different effects in my photos?
Now that we’ve gone over the basics of aperture, shutter speed, and ISO, let’s discuss how you can use these settings to create different effects in your photos.
If you want to freeze a fast-moving object, you’ll want to use a high shutter speed. This could be something like a bird in flight or a car racing down the street. To do this, you’ll need to set your aperture to a low number so that more light comes in and your shutter speed to a high number (1/1000 or higher).
If you want to capture the motion of a slow-moving object, like water flowing over rocks, you’ll want to use a low shutter speed. This will result in a longer exposure time which means you’ll need to use a tripod to keep the camera steady. Set your aperture to a high number (f/16 or higher) to keep everything in focus and your shutter speed to a low number (1 second or longer).
What are the best settings for aperture, shutter speed, and ISO for different situations?
The best settings for aperture, shutter speed, and ISO will depend on the situation.
If you’re shooting in bright sunlight, you’ll want to use a low aperture (f/16 or lower) to keep everything in focus. Your shutter speed can be set to a moderate number like 1/250 or 1/500. And your ISO should be set to a low number like 100 or 200.
If you’re shooting in dim lighting, you’ll want to use a high aperture (f/2.8 or higher) to let in more light. Your shutter speed will need to be set to a low number like 1/60 or 1/30. And your ISO will need to be set to a high number like 800 or 1600.
If you’re shooting a moving object, you’ll want to use a fast shutter speed like 1/1000 or 1/2000. Your aperture can be set to a moderate number like f/8. And your ISO should be set to a low number like 100 or 200.
What are the tradeoffs between aperture, shutter speed, and ISO?
Aperture, shutter speed, and ISO all have tradeoffs that you should be aware of.
Aperture: A lower aperture (higher number) results in more light but a deep depth of field. A higher aperture (lower number) results in less light but a shallow depth of field.
Shutter Speed: A faster shutter speed results in less light but freezes motion. A slower shutter speed results in more light but captures motion as a blur.
ISO: A lower ISO results in less noise or grain but needs more light. A higher ISO results in more noise or grain but can be used in low light conditions.
What are some common mistakes people make when using aperture, shutter speed, and ISO?
Some common mistakes people make when using aperture, shutter speed, and ISO include:
Not understanding the tradeoffs between aperture, shutter speed, and ISO.
Using too high of an aperture (low number) which can result in photos with a shallow depth of field and less light.
Using too low of an aperture (high number) which can result in photos with a deep depth of field and more light.
Using too fast of a shutter speed which can result in photos with less light but frozen motion.
Using too slow of a shutter speed which can result in photos with more light but blurred motion.
Using too high of an ISO which can result in photos with more noise or grain but can be used in low light conditions.
Using too low of an ISO which can result in photos that need more light but have less noise or grain.
How can I use aperture, shutter speed, and ISO to control the exposure of my photos?
If you want a bright photo, you’ll need to use a low aperture (high number), a fast shutter speed, and a low ISO.
If you want a dark photo, you’ll need to use a high aperture (low number), a slow shutter speed, and a high ISO.
Remember that aperture, shutter speed, and ISO all have tradeoffs that you should be aware of. A lower aperture results in more light but less depth of field. A faster shutter speed results in less light but freezes motion. And a higher ISO results in more noise or grain but can be used in low light conditions.
How can I use aperture, shutter speed, and ISO to create shallow depth of field or bokeh effects?
You can use aperture, shutter speed, and ISO to create shallow depth of field or bokeh effects.
To create a shallow depth of field, you’ll need to use a high aperture (low number) and a low ISO. This will result in a photo with less light but a shallow depth of field.
To create bokeh effects, you’ll need to use a high aperture (low number) and a fast shutter speed. This will result in more light but the background will be blurred.
How can I use aperture, shutter speed, and ISO to freeze or blur motion in my photos?
You can use aperture, shutter speed, and ISO to freeze or blur motion in your photos.
To freeze motion, you’ll need to use a fast shutter speed and a low ISO. This will result in less light but the subjects will be frozen in place.
To blur motion, you’ll need to use a slow shutter speed and a high ISO. This will result in more light but the subjects will be blurred.
Conclusion
Aperture, shutter speed, and ISO settings are used to control the exposure of your photos. Aperture controls the amount of light that comes in, shutter speed controls how long the shutter is open, and ISO refers to the sensitivity of your camera sensor. These settings can be used to create different effects in your photos. Experiment with different settings to see what works best for different situations.
