signatures: [images.Brightness PERCENTAGE]
toc: true

The percentage must be in the range [-100, 100] where 0 has no effect. A value of `-100` produces a solid black image, and a value of `100` produces a solid white image.
## Usage
Create the image filter:
```go-html-template
{{ $filter := images.Brightness 12 }}
```
{{% include "functions/images/_common/apply-image-filter.md" %}}
## Example
{{< img
src="images/examples/zion-national-park.jpg"
alt="Zion National Park"
filter="Brightness"
filterArgs="12"
example=true
>}}
