Adjusting Color and Tone with Tint

The foreground and background elements in a composite are almost always created with completely different cameras and lighting conditions, or sometimes you may be combining live–action footage with computer generated imagery. Making a couple of quick tonal adjustments can help hold the composition togther.

1. Add an Adjustment Layer above the background layer in your composition by choosing Layer > New > Adjustment Layer.

2. Add the Gaussian Blur effect to the adjustment layer.

3. Raise the Blurriness property until the background color merge together leaving you with what looks like dark and light smudges.

4. Add the Tint effect to your foreground layer.

5. Activate the Tint effects black pipette (eye dropper) and click on the darkest area in the background layer.

6. Activate the Tint effects white pipette (eye dropper) and click on the darkest area in the background layer.

7. Delete the Gaussian Blur effect from the Adjustment layer.

Applying a Color Look to hold it all together

Even with color correction sometimes the differences between composite layers is still noticeable. A color look can be used to blend the layers together and stylize the look of the comp.

1. In the Timeline panel, move the adjustment layer to the top of the layer stack and rename it Color Grade.

2. Add the Lumetri Color effect to the adjustment layer.

3. In the Effect Controls panel locate the Creative group of the color effect.

4. Choose the look you want to apply from the Look menu.

   NOTE: You can use the Browse option in the Look menu to load your own custom look file.

5. Save your file.
