Hey guys, I'm trying to match the white background (one camera angle and one actor) with another camera and angle shooting the other actor. See screenshot.

thanks

That's often a trickier task than you would think at first.

I would probably do a bit with the White control against the Highlights control in the Basic tab, trying to push the whites last little bit up while using pulling down highlights to keep as much detail as possible. Might get a little bit of improvement there.

Then I'd go to the HSL tab, and use the mask controls to select the white ... starting with only the Luminance key selected, see how 'tight' a key I could get with Luminance ... then add Sat if needed to see if I could get some more.

You might still not get everything, and ... putting a mask fairly close to the subject, then lightening the area outside the masked subject, would get the rest.

Hello @Mr. Mackey - mmmmkaaay,

Good advice here. You can also try the "Color Match" feature in "Comparison View." That gets it close. Glad you are set up. What did you end up doing?

Thanks,

Kevin

I was able to adjust the white balance to match the white background in both shots but that messed with the flesh tones and washed out the colours of the actor’s clothing. Took me a couple of hours to go through all the shots and re-tweak everything. Not perfect but happy overall. Film crew, could have done a better job of lighting IMO.

Thanks guys

Correctly lighting and exposing high key is rather difficult. You need to have the subject far enough from the background that the lights hitting the background don't also hit the subject.

And like green screen, the background must be absolutely evenly lit, and a precise amount more than the subject. Not enough, it's not close enough to white.

But too much, and bounce from the background will cause lens flare and mush your details and colors pretty bad.

Everyone's mileage always varies ...

Thanks Neil for your reply and input. I did mess around for a couple of hours and did manage to improve matching the white backgrounds with the two cameras.

Thanks again for your input.

Have you tried using the Lumitry white balance?

Thanks Richard, I did spend a couple of hours tweaking the best I could. There is a vast improvement on matching the white background with the two cameras.

Thanks again for your reply.
