# Enhance lighting and colors Image lighting, colors and contrast can be also enhanced. It can be done with 3 types of enhancements: light, color and white\_balance. ```json { "enhancements": ["light", "color", "white_balance", "exposure_correction"] } ``` Those types of enhancements can be parametrized further. ```json "light_parameters": { "type": "contrast", // "hdr_light" | "hdr_light_advanced" "level": 0.8 }, "color_parameters": { "type": "contrast", // "hdr_light" | "hdr_light_advanced", "level": 0.8 }, "white_balance_parameters": { "level": 0.8 } ``` ### Types of light and colors algorithms Let's check the various combinations of light algorithms enhancements. Our input image:

The results of 3 light enhancement types. {% tabs %} {% tab title="hdr\_light\_andvanced" %} ```json { "url": "https://deep-image.ai/api-example3.jpg", "enhancements": ["light"], "light_parameters": { "type": "hdr_light_advanced", "level": 1 } } ```

{% endtab %} {% tab title="hdr\_light" %} ```json { "url": "https://deep-image.ai/api-example3.jpg", "enhancements": ["light"], "light_parameters": { "type": "hdr_light", "level": 1 } } ```

{% endtab %} {% tab title="contrast" %} ```json { "url": "https://deep-image.ai/api-example3.jpg", "enhancements": ["light"], "light_parameters": { "type": "contrast", "level": 1 } } ```

{% endtab %} {% endtabs %} The input image which is little bit desaturated.

The results of color enhancements {% tabs %} {% tab title="hdr\_light\_andvanced" %} ```json { "url": "https://deep-image.ai/api-example3.jpg", "enhancements": ["color"], "color_parameters": { "type": "hdr_light_advanced", "level": 1 } } ```

{% endtab %} {% tab title="hdr\_light" %} ```json { "url": "https://deep-image.ai/api-example3.jpg", "enhancements": ["color"], "color_parameters": { "type": "hdr_light", "level": 1 } } ```

{% endtab %} {% tab title="contrast" %} ```json { "url": "https://deep-image.ai/api-example3.jpg", "enhancements": ["color"], "color_parameters": { "type": "contrast", "level": 1 } } ```

{% endtab %} {% endtabs %} Combining all together. {% tabs %} {% tab title="hdr\_light\_andvanced" %} ```json { "url": "https://deep-image.ai/api-example3.jpg", "enhancements": ["light","color"], "light_parameters": { "type": "hdr_light_advanced", "level": 1 }, "color_parameters": { "type": "hdr_light_advanced", "level": 1 } } ```

{% endtab %} {% tab title="hdr\_light" %} ```json { "url": "https://deep-image.ai/api-example3.jpg", "enhancements": ["light","color"], "light_parameters": { "type": "hdr_light", "level": 1 }, "color_parameters": { "type": "hdr_light", "level": 1 } } ```

{% endtab %} {% tab title="contrast" %} ```json { "url": "https://deep-image.ai/api-example3.jpg", "enhancements": ["light","color"], "light_parameters": { "type": "contrast", "level": 1 }, "color_parameters": { "type": "contrast", "level": 1 } } ```

{% endtab %} {% endtabs %} ### White balance correction White balance can be also automatically fixed if it went wrong with camera's settings.

```json { "enhancements": ["white_balance"] } ```

### Exposure correction Exposure can be corrected with "**exposure\_correction**" enhancement type. This algorithm works different than previous "**light**" enhancement. It corrects image globally with amending its with gamma correction. ```json "enhancements": ["exposure_correction"] ```
