I know what you are thinking ..... Why do I must use gamma = 2.2 ???? I already did it.. and I continue using gamma = 1

I have always thought that renders I have gammacorrected to 2.2 have looked washed out, no matter what monitor I have watched it on. Though, It must be said that I don't fully understand gammacorrecting

A looks a lot better to me and I keep my screen fairly bright

Definitely A. Will you tell us the technical difference between them later?

I bet $10 that the image A is using gamma = 1 and B gamma = 2.2

I think that's going to cost you $10

I've tested it by applying gamma 2.2 to image A, and image B is still brighter (about 4%).

Yes, Image A was rendered with "Gamma" set to 1.0 and Image B was rendered with it set to 2.2
I wanted to see if everyone else was seeing what I'm seeing on my monitor and it looks like they pretty much do.
But the downside is I'm still confused by the whole gamma calibration thing. By all tests my monitor is not gamma calibrated correctly and yet this mis-calibration seems to be the only way to get a visually correct display result.

I asked the Head of Technology' at my company about gamma-correction too... he said he did'nt fully understand it 100% either but went on a rant about Apple 'messing with everyone's head' by setting their systems at a different gamma...then we laughed over the 'better' slogan.
I think Yves was the only one who fully understood it... and he's not around too much anymore.

I'm there. My frustration with that gamma issue is that I understand it quite well. But it seems that no matter how I try to explain it, I just succeed in confusing some people more and more. Not just here on the A:M forum but with other people I discuss that as well. I think this is just a too complex issue or I'm not a good communicator. I tend to believe the former because I read other forums and blogs where knowledgeable people try to explain that as well and they also get the same string of confused replies. I think I had a pretty good tutorial on the subject on my web site. I think I explained all there is to know to get linear workflow in A:M. I added some extremely simplified set of rules on this forum. I don't know what I can add more.
