I have a multi camera setup, and one camera shot warmer than the other. For example, one is 5600K and the other is 3600K.
Instead of playing around with a three-way color corrector (which never seems to get the right results for me to just get a *warmer* image), is there a simple slider that increases the warmth of the picture as if I were white-balancing on a camera? Seems like it should be a no-brainer...

Peter,
I have already filled out a feature request with that content, a White Balance effect with a slider in K, similar to the white balance settings on the Canon XF300/305. The clips white balance info is contained in the metadata of the clip, so it should not be rocket science to modify the color temperature from say 5600 K to 6100 K by means of a slider and have the results reflected directly in the monitor. The huge benefit is that if you forgot to white balance with a warm card, it is extremely easy to add that in post.
Please fill out a feature request as well, the more people requesting this effect, the sooner it may be implemented.
Here is my original request:
Would it not be nice to be able to extract the WB settings in K from the metadata and be able in post to change it to what you should have done during the shoot.
Say your WB is set to 5600 K, you can extract that from the metadata and with the White Balance effect you can enter a desired setting of say 6100 K. During the shoot you can do that with the Canon XF series, but if you have forgotten to use a warm card instead of the white balance card, this would be a great effect to have. Or in the situation where you simple want a shot to be slightly cooler or warmer, this would be a great feature.
Interface similar to the scale slider and fully keyframeable. The program monitor should reflect changes in color temperature immediately. Simple, easy to understand, like using a set of Warm Cards after the shoot.
Retrieval of the color temperatures should not be difficult, see attachment.
It works both with AWB and manual for the XF series. If the camera does not record these data, the effect should be greyed out.
PS. I have called in reserve troops to support this request. See http://forums.adobe.com/message/4320392#4320392

Just discovered Magic Bullet Mojo's "Warmer" slider works pretty nicely, but I'm all for your feature request!

Peter,
Thanks for that tip. While waiting for Adobe to honor this feature request, I just upgraded my MB Looks to MB Suite and that includes all 9 MB plugins, including Mojo. While not as simple as our suggested solution, it is nice to have a relatively simple solution like that.

There's a WB eyedropper in one of the color correcting tools -- I forget which -- and it works sort of OK. I find I have to apply it two or three times to get it perfect.
I believe Photoshop has the exact type of tool Harm is proposing, so I'm hoping it will be an easy add for the Premiere team.

Well I've changed my mind a bit... even after Mojo, I'm just not happy enough with the adjustment.
Here is camera 1:

Camera 2 (the one I'm trying to modify)

By making the image "warmer" enough in Magic Bullet Mojo so that the skin tone looks decent, the blues turn into a magenta.

This is with the warming slider at about 60%. 15% is a happy medium but the skin tones that camera 1 has aren't remotely there.

If you look at the vectorscope there is no skintone at all in camera 2.
I think this is nearly impossible to correct.
