WB Sensitivity

A

I have been shooting with the gh2 for a little while and I have come to notice something interesting with the WB. The in camera WB presets tends to shift a little to the yellow side as if they are trying to artificially warm the image. This happens under most settings, especially in the outdoors presets. It can be easily corrected by dialing in your WB in the K setting. I noticed that the AF100 behaves similarly in that it is really sensitive to its WB. By lowering the in camera saturation it helped control the colors better on the gh2. I haven't had a chance to muck around with the image settings on the af100 much but I'm sure it will yield similar results.

I was wondering if anyone else noticed this?

I am going to toy around with the fine tuning adjustment a little to see if I can just correct in camera. Ideally I would like to have as clean an image as possible before I start color work.
 
GH1 gave tad bluish skin tone. I shifted WB color to "Y"ellow by one step on all film modes. -2 on saturation and contrast settings. Then boosted during post-processing.
 
I use manual WB, period. I don't trust auto or any of the presets. Pros carry a white card with them, I just pick something nearby that's white and make it look white in the EVF.

That is a good practice. You still have to know your gear and understand what it is doing. You can still White Balance "wrong". Video shooters with years of experience understand what I am saying.
People starting out need to practice, practice, practice. I also get one clip with the white card in each new scene. It helps in post.

This is very good advice. Good thing is that it is very easy to color correct/WB in camera with the GH2. My first gh2 shoot showed a slightly yellowish tint. My canons always pushed a bit red.

The majority of the time I use a white card but in some situations I don't always have that liberty so I end up hitting a preset like daylight (never auto). I have heard of the practice of putting a white card (or a 18% grey card) in the scene but never tried it. I presume that it makes color correcting a lot easier in post?

Well it can get you close. In FCP using the 3 way CC you can use an eye dropper to pick WB. If you have a clip with the white card in it - it makes
it much easier to get to neutral before trying to CC.
