The values you enter for these sliders will change based on the image
properties and key color you choose. The values can even be different
when used to create transparency on the same image in two different
shows.

Thankfully there’s a set methodology you can use to get solid results. You
don’t even need to know exactly how the sliders work.

Here’s how you go about it:

1. Begin at the top of the sliders, with Hue Threshold, and adjust the
slider slowly to the right while looking at your image in the
Preview. Adjust the slider to the right as far as you can without
causing regions you don’t want to alter to become transparent.

2. Begin moving the Hue Drop Off slider to the right in the same
way once you’ve adjusted Hue Threshold as much as you can.

3. Continue in this manner to the bottom of the sliders.
