Re: workflow : 2 panels to see changes from 1 effect

Thank you Stuart, you wrote exactly what I was about to answer.
I read (Keylight User guide p 24) that "It can also be useful to view the Status and Source side by side as shown in Figure 14 so that you can repeatedly pick from one while viewing the result in the other window."

But in fact, it seems the trick here is to open a footage window next to the Comp window.
That's great if you want to compare a "status" or a "final result" to the source. But it means also the trick is useful only for the "Source" view.

Thank you for your answers. And if you have other ideas, I'm always interested. ;-)
