# Contrast
> Widen or narrow the gap between light and dark areas with the e_contrast token.
Contrast controls the gap between the light and dark areas of an image. Raise it for a bold, dramatic look; lower it for a softer, muted one.
Add the `e_contrast` token to the transform segment of any delivery URL:
```bash theme={null}
https://assets.autorender.io/LOKVTtKVGb/e_contrast:30/docs/example/porsche.jpg
```
## How does it work?
`e_contrast:{level}` takes a level from **−100 to 100**. Negative values compress the tonal range for a softer image, positive values expand it for a more dramatic one, and `0` leaves the image unchanged.
## When to use it
* Add punch to bold, striking images.
* Soften portraits with a lower level for a flattering look.
* Make product colors and edges stand out.
* Emphasize detail in landscape shots.
## How do you combine it with other effects?
Chain contrast with brightness and saturation in one comma-separated segment. We recommend levels between **20 and 40**, because higher levels crush shadows and blow out highlights (e.g. `e_contrast:25`).
```bash theme={null}
https://assets.autorender.io/LOKVTtKVGb/e_contrast:25,e_brightness:10,e_saturation:15/docs/example/porsche.jpg
```
## Next steps
Lighten or darken the whole frame with `e_brightness`.
Adjust color intensity with `e_saturation`.
Define edges and detail with `e_sharpen`.
