GoPro ISO is a setting that controls the image sensor’s sensitivity to light. A higher or lower ISO value setting means the image sensor is more or less sensitive to light, which results in either brighter or darker footage.
Why You Should Keep GoPro ISO Low
High ISO values can produce “grainy” video footage. By understanding GoPro’s ISO capabilities you will learn how to correctly adjust your ISO for any lighting situations. But generally, try to keep a low ISO value (not more than 400) to get the best video quality possible and avoid video noise.
GoPro ISO Comparisons
In Auto mode, your GoPro will vary its ISO value according to surrounding light levels. Flip on Protune and you can control ISO at your discretion.
GoPro ISO vs Video Noise
*Video Noise (High – Medium – Low) / for better results keep it low!
- ISO 100 (low)
- ISO 200 (low)
- ISO 400 (low)
- ISO 800 (medium)
- ISO 1600 (medium)
- ISO 3200 (high)
- ISO 6400 (high)
There are some risks to assuming manual control of your camera’s ISO levels. Choose too low and you risk underexposed footage. Conversely, setting it too high may brighten your video, but you also risk producing a grainy effect — something often called “noise”.
The following images show the differences between a well exposed photo with the maximum ISO level kept to a low value (eg. ISO max. 200) and a noisy photo having a higher ISO level (eg. ISO max. 1600).
Suggested GoPro ISO Values
To be safe and to avoid noisy images and footage, keep ISO min. at 100 and ISO max. at 200 or 400.
Finally, if you realize that your footage looks too dark in low light, instead of increasing your ISO levels, you might try using an external light source to brighten your setting, like in the image below.
- How do you change the ISO on a GoPro?
Make sure Protune is activated.
You’ll be prompted on a settings window with two ISO values: ISO Min and ISO Max:
By default, your GoPro has ISO Min set at 100 and ISO Max set to 3200.
Keep ISO Min. at 100 (this is the lowest ISO value that the camera will adjust when it’s bright)
Adjust ISO Max. according to your lighting conditions but remember that high ISO values will produce image noise.
This video shows how to change GoPro ISO values (on GoPro HERO 6):
- Why change GoPro ISO settings?
Default ISO values may produce image noise since ISO Max. is as high as 3600 ISO. So I’d suggest to change your ISO values according to the lighting conditions. If your scene is bright then keep both ISO values low.
- Best GoPro ISO settings for low light?
In low light situations you are forced to increase the value of GoPro ISO settings. But bear in mind that high values (like 3200 and 6400) will produce image noise. So instead try to brighten up your scene with an external light and keep ISO values as low as possible.
But generally, when filming in low light adopt these ISO Settings:
- ISO Min: 100
- ISO Max: 1600
- What does ISO limit mean on GoPro?
GoPro cameras let users take control over the range of ISO values through ISO Min and ISO Max. After you set these limits, the camera will adjust the brightness of the image based on ambient light and the limits set.
If you would like to have a fixed ISO value (not variable) then set ISO Min and ISO Max at the same value. For Example:
- ISO Min: 100
- ISO Max: 100
- Does changing the ISO on GoPro change the image quality?
Your GoPro camera will produce a better image quality at lower ISO values, while at higher ISO values and in low light, video noise is likely to occur.
Generally, to keep high image quality, just ensure that your scene is well lid and GoPro ISO Settings are set at “low noise range” – between 100 and 400.
