GH2 official discussion thread

Vitaliy, This is not a hack request, but from your knowledge would you think this is possible. I've been doing HDR still images. Getting amazing tones. I know the Red has HDR. So, can say in 50 fps the shutter be alternated every other frame. One correct exposure then a 2 stop over or under? Then processed in post to 25 fps HDR?

I mean can the shutter be adjusted that quickly?

I don't know.
May be.
Problem is that it won't by HDR anyway, as two frames will be different if any motion is present.

Also different shutter speeds would give different motion blur. Best would be switching ISO. You might get away with it at 60fps with minor motion (or 120fps with more :)).
 
Frankly what you can get from HDR is far more interesting than 3d. Take a look at a shot at night on a street or in a room at night. Not a crazy HDR, but just a bit of detail enhancement in the shadows would made a shot amazing. I'm not thinking for every shot, but one of those problem lighting situation. All the processing is done on a computer in post.

Just the camera needs to alter ISO or Shutter speed. And no, this wouldn't be used for a car chase or fight scene. Shots without quick motion.

If it is not difficult for the camera's hardware to vary the shutter or ISO in a fraction of a second, This could be a cool, easy implementation for Panasonic. New GH-3 with Cinema HDR mode!!! Take that Canon! Pow!!!
 
You know, it's funny. I first watched it in non-HD (because of Vimeo's annoying default settings for embeds), and I didn't even notice it wasn't in hi-def. That's a compliment!

Then of course I watched it again after turning on the HD, and then it really popped.
 
nice shot pilipo, is it color corrected on post? hi anybody can help me where i can buy spare battery for my gh2 ???
thankx all
 
Just spent the past 2 days looking at every comment and clip / review on this megathread. 2 days well spent I think. I would ask people to post a bit quicker from here on in as I've run out of reading (& learning) material. At least until my GH2 arrives. If I can be of use in the testing arena (while learning something at the same time) then I'd be more than happy to oblige VY. (Being a step-up from an amoeba with my 1 post must make me a guaranteed runner I'm sure:).

Sure, but it is more correction as grading. I have used a false WB and i must correct this in post but the result is still very well i hope.
 
I've searched but haven't found a direct answer to this question. Can anyone confirm the native resolution coming off the sensor in video mode. Is it truly 1920x1080 or is some other voodoo happening as on my 5D?

Thanks.

I have no idea but it looks really good.
I need to shoot some more - that darn corporate work all week gets in the way...
Finally got two more batteries so now I can test it out on the paying gigs.
 
Questions about comparative detail from GH2, EX1R and Canon 5D

I made a 9 1/2 minute Blu Ray disk of various clips I shot in different modes, and watched it on the large Sony TV. These are a few of the clips in the Blu Ray, http://www.vimeo.com/19066379
I watched it three times and made notes the last time.

But first, before the notes on the film modes, I have a question. I was amazed at the detail I was seeing in the rocks. I remember being disappointed at previous shots with the EX1R, This was also true for the video of this area I made when I tried a Canon 5D, http://www.vimeo.com/6186358. I then watched a Blu Ray I shot in the fall with the EX1R, http://www.youtube.com/user/billh96007#p/u/11/ew5DsDOivGc and there is lots of detail in the people (at 3:28) and Blue Heron (4:25). The rocks are in this EX1R video, http://www.vimeo.com/8769320 at 2:05, and while the I see impressive detail in the GH2 video, the same rocks look almost smeary here in the EX1R video. The birds are great though. What is the difference? Is it something about the larger sensor in the GH2? I would love to understand why the GH2 is so good here, and the Canon 5D and Sony EX1R comparatively so bad in this one area.

Notes I made on the film modes while watching the Blu Ray:

Cinema: Darks too dark, no detail. Water highlights good, retained lots of detail. Darker area, (zone 3 - 4 ) flat and dull.

Standard: Like Cinema, Blacks have no detail. Cinema may look a bit better in the dark areas.

Dynamic: Maybe a bit better detail in the blacks? Overall I like Cinema best of these three.

Nature: Blacks crunched here too, but held some detail in the blacks.

Vibrant, no detail in blacks, whites holds detail.

Nostalgic: I hate the yellow. I left it in for the short examples I posted on Vimeo, but removed most of it for the Blu ray clips. On the Blu Ray I can see I could have tweaked it a bit more in the whites, but on the computer monitor, if I removed any more yellow from the mid tones, some of the rocks became an unnatural steel blue. I think this is the most interesting of the modes. I used these clips, http://www.vimeo.com/18937528 as the opening clip in each of the modes in the Blu Ray. My notes say, “best by far in the opening blacks, good detail in middle tones, whites OK. My wife commented on the beautiful colors in the rocks in some of the clips. They did look natural and appealing, and held a lot of detail, but I am not sure they are really representative of what you would see if you were there looking at them. I’ll have to check that.

These notes are made while watching a Blu Ray conversion. I output a ProRes HQ copy and watched it, and it is pretty much what you see in the Vimeo clips.
Nostalgic and Smooth are best, probably Nostalgic no. 1 and Smooth no. 2, but get all of the yellow out of the Nostalgic clips. I wonder if I can do this in the WB menu?
