I just want to say that I think, Jeff analyses of the photograph was a really good one, I just wanted to bring something that maybe he didn't see and
would bring another aspect to the study of this picture. (see my other post to know what I'm talking about). And I think that most of you guys are
the same. I don't think it's fare to say that the way he did his analyses is not the right way. I never worked myself with the Lab Colors mode but I
won't dismiss it has a bad tool. If your used to it why not. Here is some excerpt from wikipidia.
"Unlike the RGB and CMYK color models, Lab color is designed to approximate human vision. It aspires to perceptual uniformity, and its L component
closely matches human perception of lightness, although it doesn't take the Helmholtz–Kohlrausch effect into account. It can thus be used to make
accurate color balance corrections by modifying output curves in the a and b components, or to adjust the lightness contrast using the L component. In
RGB or CMYK spaces, which model the output of physical devices rather than human visual perception, these transformations can only be done with the
help of appropriate blend modes in the editing application.
Because Lab space is much larger than the gamut of computer displays, printers, or even human vision, a bitmap image represented as Lab requires more
data per pixel to obtain the same precision as an RGB or CMYK bitmap. In the 1990s, when computer hardware and software was mostly limited to storing
and manipulating 8 bit/channel bitmaps, converting an RGB image to Lab and back was a lossy operation. With 16 bit/channel support now common, this is
no longer such a problem."
It looks good to me, I think it should be the new way to work with all the HDR images on the market now.
Please lets us work together on this, nobody is better then the other, just maybe more experience and that's all. Even with all the experience in the
world you will miss something, trust me I know. I'm just saying that together we have more chance to solve this.
