GH1 adobeRGB and sRGB comparison

This seemed like a good time to actually register and post something. Not that I have time for another forum in my life but I can't hold myself back any longer.

As far as I know AdobeRGB stores more color information than sRGB. I don't think this necessarily warrants sRGB being considered "compressed and unnatural" since you often run into the problem of AdobeRGB images being viewed in an sRGB color space and looking washed out, which I would call less natural. Which makes me wonder if the less saturated look of filming in AdobeRGB isn't caused by this somehow. Not that I actually know how, but it's something that I'd hope someone who knows more than me would look into.

Also maybe this question has an obvious answer, but was this filmed in AVCHD or MJPEG? From my photography knowledge it seems obvious how this could affect MJPEG, whether it is supposed to or not, but what about AVCHD?

Reading this post it doesn't quite seem enough to have pushed me over the edge into registering but I guess I was looking for any excuse at this point.
 
Nostalgic has much less contrast than all the other film modes. Smooth and Nostalgic are right next to each other in the menu...switch back and forth between the two while pointing your camera on a colorful and complex room in your house(for example)...you should notice the difference.

I used smooth for a long time after my first GH1 purchase over a year ago- but since going to Nostalgic, I haven't looked back- you'll find many a thread on this subject.

@ChrisLight-

My home office is a 'red' room, definitely a good example of displaying differences between SMOOTH/NOSTALGIC & sRGB Adobe RGB. ....I found some comparison footy btw- will throw up over the wekend.

cheers
 
Hi,

Any difference in file sizes? If Adobe RGB has more information for the same duration, than that's really interesting.

In the post that Barry Green did where he had a step chart, "Smooth" and "Nostalgic" appeared to have nearly identical indiciations of latitude. "Nostalgic" seemed to give the 'grey' step wedge a 'sepia cast'.

From Simon Höfers post, he didn't mention what other parameters he had his camera set to, such as 'smooth', or 'nostalgic', etc.

Since 'nostalgic' seems popular I could perhaps assume that he had that set.

But with the sepia cast... would that not imply there is more 'red' added... for the cast... so, with the difference in reds using the Adobe RGB setting, it seems like a bit of compensation for the 'nostalgic' setting...

One of these days I'm going to get time to do a bunch of tests... one of these days...
 
Ok... done some experiments with this on stills.

1st - there is a slight difference - but not enough to fix the blown out reds on AWB from what I can see - I am going to stick to the method I outlined in the previous thread.

2nd - weird thing... please confirm why this is guys. If I have adobe RGB set... when I put the memory card in my PC.... IT CAN'T SEE ANY OF THE PICS! Weird!

I need to use photofun to aquire the card... then I can see them.... but I can't just browse the card directly like I normally would... it is like all the files are hidden somehow.

Any idea why this would be?

hmmm- haven't heard of this, but I'm on MAC
 
Can I make a quick suggestion. This may or may not be relevant to this discussion. What I say is based on still image experience. Usually for the internet you use sRGB on stills because the internet is set up around this, and until recently most browsers were not colour profile aware i.e. I think they assumed it was sRGB. If you view a still image with an attached Adobe RGB profile on a none colour profile aware browser, the image appears very flat and lacking in contrast, with muted colours. However, if you view the same image on a colour profile aware browser it will appear contrasty and have punchy vibrant colours.

I am not tech savvy enough to know what the situation is as regards video software and its recognition of different colour profiles. Nevertheless I think it is worth checking whether the flat look obtained by using Adobe RGB is actually as flat as it appears, or whether it is the way the software is reading or not recognising the colour profile. If it is the same as stills, this flat looking image with muted colours, may look quite different if played back on software that recognises the colour profile. Hopefully others with a bit more tech sense will know more about what colour profiles video playing software recognise and display properly.

Edit: I just noticed that bobbylandry made a similar point to mine, about what happens when you view something with an Adobe RGB profile in an sRGB colour space i.e. it looks washed out. It has also occurred to me that what may be happening with the GH1. If the footage is recorded in, but not tagged with the Adobe RGB colour profile, when viewed it may be defaulting to an sRGB colour space i.e. Adobe RGB is being viewed in an sRGB colour space. There's a bit of info in the 2 links below about this issue.

That may be true, but it is also important how well you can grade the footage. You will grade it on a calibrated monitor. No one is suggesting, I think, that you record superflat with minus settings and then use that as the final product. If you want OOC, then you will of course add a some contrast, sharpening, etc.

Back in the olden days, some set of my friends use to use 'movie' negative film for shooting stills, mainly because of its 'flatness', then perk it up.

I never shot color film back then so I never tried it...

Hey folks,
as mentioned in the GH1 - Tips and Tricks thread I made a comparison of adobeRGB and sRGB on the GH1.

You can change it in the PICTURE settings when you set the dial to M mode. Then switch back to Movie Mode and shoot some video.

It makes absolutely no sense that there is any difference in movie mode, but it definitely is different.

See for yourself in this video:

My compliments. I knew there was a difference and you have provided proof.
