GH2 Calibrate your LCDs

GH2 Menu > Setup Menu > * Monitor

Feed an HDMI signal out or shoot something, take it to your NLE, and match the image back to that.

Makes being fooled by white balance less likely... cause it definitely got me.

Second step:

Go into the LCD/EVF saturation and contrast settings (*monitor in menu)

Push the contrast slider all the way to the top, and the saturation slider all the way to the left (desaturate).

This will help you judge what's actually blowing out and what's actually under. You can set EVF and LCD independently, so you can have one to normal and one to this "flat" look.

Good idea... but I wonder how well calibrating to one white balance setup / lighting scenario carries over to another (daylight to tungsten, etc). Also, in what way were you fooled by white balance? I thought the Gh2 LCD is notoriously bad in terms of both color and white balance in terms of accurately representing what's being recorded.

Quite well, from my experience. + 3 green and + 1 yellow has worked quite well for me. The only problem is that it makes the image a bit "muddy", but it's worth it to see a more accurate image.
 
A calibrated monitor will always be accurate no matter where you go.

You have to calibrate to an external source that's accurate though.
 
Matthew P: There's a difference I think between the calibration you are talking about and what kholi is mentioning. You are calibrating color profile / white balance. Kholi's calibration only affects the lcd monitor (and monitoring via hdmi output?).
 
Only the LCD and EVF. Hdmi out is unaffected and showing you what the camera is actually seeing versus what the LCD is reporting.
 
Other issue's that the LCD wants to tell you that your shadows/toe's gone much faster than it really is. HDMI out reveals that we may sometimes be uneccessarily pumping the ISO up out of fear of dark areas, but there's still PLENTY of info there.

It's surprising to know that in situations I thought required 800 ISO to expose the lower end didn't need more than 400, and was very clean.

Actually, no, I was referring to the colour settings within the monitor menu, not white balance. :) Hit "display" when you're at the point where you can alter brightness and colour (colour does nothing remotely like what it's supposed to), and then you can correct the monitor's unnatural tint.
 
Just to clarify - the recommendation is to compare GH2 lcd against a calibrated monitor in the edit suite?

HDMI out of the Camera to a Calibrated monitor. You could also compare it to a Calibrated set from recorded footage I'd suppose but you have to account for any shifts your NLE or OS might be responsible for.
 
This was great advice - set up my gh2 lcd against our JVC Broadcast HD monitor, and it's made a world of difference.
 
Bumping an old thread, but I'm curious what you recommend without access to a calibrated monitor that I trust to use as reference? Any ball park settings that may not be perfect but better than factory settings?

Hey sorry I missed this. Some people are getting by fine with just a +magenta adjustment, so that you don't have to do it in post. Try that.

Also, just changed the first post with a suggestion to adjust contrast and saturation on either EVF or LCD.
