Makeup showing up with greenish hue

[axel ebermann]

Hey guys,

Here is a new, very unpleasant phenomenon, that
I have witnessed during some of my recent productions.

What seems to happen is that a certain kind of makeup gives off a greenish hue. The more make up needs to be layered on (for example because of wrinkles etc.) the worse it seems to get.
You see the difference if you compare the skin tone in areas where no make up is applied to the skin tone where more make up is applied - for example around the eyes.

I experienced that on several productions with several make up people who I know are good at what they do.
They swear they did not change the brand or mix of the makeup.
However I have never seen this before.

Because strangely everybody always likes to blame everything on the Red One I took some stills with a 5D on the last set and the green is also there - although not as pronounced.

The unpleasant thing about this is that you cannot easily time out the green without bringing the rest of the skin tone towards magenta.
You can key it out with a proper color timing - however a lot of clients don't do that because of timing and budget restraints and what you end up with are high end promos that go on air looking absolutely awful...

The sample pictures are not color corrected on purpose by the way.

Anybody got any wisdom to share ? Would be very much appreciated.

What kind of lights were used?

I have seen it once before and if I remember correctly it was a combination of make-up and fluorescent lights. Most fluorescent lights have a peak somewhere in the green spectrum that is normally not visible unless there is something that matches that color, and then that object tends to lights up green.

The better the lights, the less pronounced the effect is but with faces you need only a tiny bit of it to see it since our eyes are so sensitive for skin colors.

also are you using redcolor2 redgamma2? it makes everything a lot more natural, especially with skin tones.

you could also change the color to "camerargb" and suck out all the hue and saturation and retime the image, and use it as ur look in RCX.

tungsten fresnels. the other set was a briese umbrella.
the strange thing is that I have shot with these lights
under similar circumstances before and it never showed up.

mr. tom,

I know how to color correct. but that has nothing to do with make up suddenly showing of greenish.

you were on one of those jobs by the way :-)

and the make up looks green. just look at the promos of the gentleman we shot together who I'd prefer not to name here because of certain sensitivities of the client...

not insulting your ability or knowledge, just trying to provide you with a better work around since you say it's very hard to knock out the hue. the leaning in color could be a lot of factors, including what was mentioned with the lighting. just wanted to give my 2 cents and help out :)

if you see it on your 5d sensor too, than I may have to agree that it is something with the lights. fluorescent lighting as you know tends to lean towards color hues such as magenta or green when they start going. I wouldn't really blame the camera if it's showing up on two different sensors.

also it could be a combo of their certain skin tone with make up making it more likely to reflect the green too. lot of variations on the issue.

no offense taken my friend :-)

I am alluding to a makeup problem though. not how
to fix a problem in post that should not pop up in the first place...

we did not use fluorescents on those sets by the way.

check out your private message and you will know exactly what I am talking about ('cause you were there...)

just thinking of it: it is not as pronounced but I can see the greenish tones
even with my bare eyes on set.

so I do not think it is a sensor problem only....

[Aaron McAdam]

So then...maybe it's the makeup? A bad batch of whatever you normally use?

[sander kamp]

I guess a stupid question but there's nothing else that can reflect green somewhere?

Otherwise I would say make-up. In the one instance I saw it on the set it went away but using different make-up.
