What if your using lighting of different temps together?
balance to a grey card has produced the best results for me, presets also seem pretty a-okay.
Dialing never seems to go well. Always notice strange noise or color shifts. If you can balance to something white or a grey card in the scene do that, but don't re-balance until you're done, or make sure you can white balance the same if you have to come back to that place.

I've also had trouble dialing in a temperature. The color doesn't seem to change the way it should as you go up and down the Kelvin scale. Odd. Also, I've found the LCD to be pretty terrible--I really need to calibrate it, but am unsure what the best approach is. Maybe that's a topic for another thread, but who here has calibrated the LCD, and how did you do it?

Pardon my stupid question, but how does one WB to a white/gray card on the GH2.. I looked all through the settings and couldn't figure out how to do it the last time I wanted to.
WB menu, second over from the right (a numbered square betwixt two right triangles)
arrow up to select white set
fill frame with white/grey; arrow up ("WHITE SET")
hit menu/set button. Shutter clicks. You're done.
Yes....well hidden indeed :thumbsup:
I have had so-so results in regards to white balance (with manual, dialing, and presets). This has actually become very frustrating for me. I always get good results with a broadcast cam, but on the GH2, I've been holding my breath every time I set the WB... I am beginning to think it might be an LCD calibration thing... but my colors have been looking pretty terrible under normal light temps.

Something I have noticed on the BTS clips for many movies. There will be someone with a GretagMcBeth color chart, which would presumably give the post-processing a guide on 'color' of the lighting. I'm sure there's white balancing as well, but it is not just left at that.
I use to have a small color chart, but it has somehow disappeared... so I use an old Kodak Field Guide, which has a B&W step chart, and a set of color swatches. The problem is I don't think the color swatches are 'NIST' traceable... so they are only really a finger in the air guide. I also have a larger Kodak 18% grey card which could be used for White Balance purposes. There are also some collapsible 'grey cards' that have a bigger area.
However, the 'grey target', needs to be placed such that the lighting on the scene/talent is measured, and not where the camera is placed, so there may be a sort of awkward, move the camera to the point where the field of view is filled with the target, then repositioned for the shot.
Of course, if the shot is outdoors, and sun light is the source, one could perhaps just make the calibration with the camera in position.

In my 'considered'... opinion... the LCD should only be used for framing... Its use for such things as color balance and exposure, seem to have many problems.

You got to be kidding me!!!
I had this cam over a year now (and the GH-1 before it) and I never tried this. I'm like a kid in the candy store now. Thanks.
EDIT: The other cool thing is....it stays there even after you power the cam off and back on. :thumbsup:
This is exactly what I meant.
Hold the grey or white card up in the area where you're lighting (so that if there's mixed light it'll catch) or balance it to whichever light you prefer (fill or key) depending on your look, set it.
You have four slots to save.

Oh DEAR LORD!
Add me to the list!
After coming from the DVX100 I fing this GH2 to be a programming NIGHTMARE!
AAAAAAUUUUGH!
But thanks!
