## How can AI fix the colors of a dark, yellowish webcam recording?

The [Tella Agent](https://www.tella.com/agent) fixes a dark, yellow webcam recording in Tella when you ask, for example, "brighten my camera and cool down the yellow cast." It raises Exposure, lowers Temperature, and adjusts Tint, Contrast and Saturation, or applies a preset or LUT. It can correct your camera without touching the screen recording.

## Prompt to start from

```text
My camera is too dark and looks yellow from a warm desk lamp. Brighten it a little, cool the white balance so my skin looks natural, and add a touch of contrast. Apply it to every clip and leave the screen recording alone.
```

## More prompts

### Real estate agent

```text
I recorded this listing intro under overhead lights and look dim and orange. Raise the exposure on my camera and cool the temperature until the white walls look white. Keep it subtle.
```

### Course lesson with a brand LUT

```text
Apply our uploaded Northwind Warm .cube LUT to the camera in every clip at about 60% intensity. If my skin looks too green, nudge the tint toward magenta and tell me the final values.
```

## How to do it in Tella

1. Open your video in the Tella editor and open the Tella Agent chat.
2. Describe the problem, like "my camera is dark and yellow."
3. Check the result and ask for changes in plain words.
4. Fine-tune any slider under Advanced in [Style → Filters](https://www.tella.com/help/editing/color-filters).

## Good to know

- Needs a paid plan or the 7-day trial. Messages use your workspace's credits.
- A filter applies to matching clips by default. Check Apply to this clip only for a clip shot in different light.
- Exposure runs from -1 to 1, where 1 or -1 is two stops, so small values go a long way.
- Custom LUTs must be 3D .cube files with a LUT_3D_SIZE of at most 65.
