How does a SLR shoot warm tones? Do you want to add a filter or something?

The question you asked actually boils down to the setting of white balance WB in SLR cameras.

Let me put it briefly:

1. The background knowledge of white balance is color temperature. The lower the color temperature, the more biased (red), and the higher the color temperature, the more blue.

If you want to shoot warm colors, you can raise the white balance color temperature of the camera.

3. Specifically, if manual white balance color temperature setting is supported, you should set the higher the color temperature value, the redder it is, and the lower the better.

4. If manual white balance color temperature setting is not supported, white balance should not be set to automatic.

5. Adjust the color temperature according to: blue sky-partly cloudy-cloudy-flashlight-incandescent lamp-candlelight. You set it to a cloudy day, or a higher color temperature.

This will make your film warmer. Of course, the color of the whole movie is warm, not partial.

In addition, you can also increase the film effect through the Twilight Mirror (orange), or you can adjust it after PHOTOSHOP.
