    returnType: images.filter
    signatures: [images.Brightness PERCENTAGE]
---

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 "/_common/functions/images/apply-image-filter.md" %}}

## Example

{{< img
  src="images/examples/zion-national-park.jpg"
  alt="Zion National Park"
  filter="Brightness"
  filterArgs="12"
  example=true
>}}
