GH1 LCD Monitor Accuracy

Hi,

I have the LCD monitor option set to OFF.

I'm finding when I take photos, the exposure or brightness is way off(darker) and it seems to vary.

If I take a shot with the rokkor-x 50mm f1.4, the image looks fine on the lcd monitor but after shot taken, the preview image, it is much darker. I shoot
on aperture mode and dial in until I get 0 on the EV meter. I'm finding I have
to bump it +2 or higher to get the same brightness as I would see live view
on the lcd monitor.

So how are you taking your shots to get accurate exposure? I originally thought
I had the lcd monitor on auto and that caused the inaccurate results, not the case.

thanks.

The liveview display is not designed to give an accurate image in terms of exposure, it's designed to give the brightest image possible to mimic an optical viewfinder. You should be using the meter and the histogram. You said you had to bump up exposure comphensation to get as bright an image as the liveview showed? Well then you're getting an image that's (in theory, but it depends on what your subject is and if it's what's being metered properly) 2 stops overexposed.

that would make sense if it looks overexposed(by 2stops) on my pc monitor but it's not.
 
Are you shooting in low light or high contrast situations? Because then it's possible the meter isn't metering accurately on what your subject is.
 
I think I understand what he's talking about. It was a big surprise to go from my DVX to the gh1 and find that the LCD was not very accurate.

In video mode, something that looks fine on the LCD can look terribly dark on the EVF or a computer screen. I did some testing and if I remember right, I compensated by changing the LCD settings to darken up so it was more accurate.

besides Bens point, i had the opposite effect. my footage when viewing on my pc is unbelievable bright. though im not sure if that's my lenses or not.
 
shooting in low light.

does vary from lens to lens. for whatever reason the rokkor-x 50mm f1.4 is more dramatic.

video seems fine, just with photos, it comes out darker.

if I take a photo with my rokkor-x 28mm, what I see on the live view, after
photo is taken, looks pretty close to the live view but with the 50mm, it's
darker.
 
It's probably more dramatic with non m4/3 lenses because they are stuck in a constant "DOF preview" mode, which is to say the aperture actually moves when you move it, it does not snap into place when you take a picture.
