so it was you who posted that graph in that old WB thread of mine. The cached version I found through Google is stripped of images. Thank you for providing it, then and now.
The value of 6,000 K (close to 5,500) did not work well in my test as can be seen.
> Also, if one wants to reproduce the appearance of the scene, chromatic and dark adaption must be taken into account. His empiric approach was relatively crude and limited by the camera's LCD, but it got the job done.
Exactly. I am of course aware of the limitations of the camera screen and the in-camera jpeg, and the precision level of 1,000°K can be raised to 100°K (on the Canon 5D2). But even at 1,000°, my "method" could do something no other method I know of can. One may see it as a crunch to a freehand estimate of the Kelvins, including not only the light, but also its reflections through the scene, and phenomena specific for human vision. Just like the grayscale step wedge in the old days was in estimating the EV.
> Even IF you could provide that your capture was colorimetrically accurate than mine, if I like my capture better, the story is over.
Andrew you are insinuating 2 things I have never claimed nor am interested in.
1-I am not talking about colorimetry. I want to reproduce the scene as I saw it. But to me this is far different from sheer arbitrariness. I just don't buy it.
2-I don't want to urge anybody to use my method. If your preferred rendering of that scene is say like the one resulting from the AWB, you're welcome.
All I wanted to do is for once give back a little to this forum where I have learned so much.
> Neither of us can provide anything scientific to say our perception of either the scene or the capture is more accurate than the other.
No we can't. The kind of science that might apply here might be something like this: I should gather xx naturalistic painters on my porch, have them look at the scene, then at the images on my calibrated screen, and have them select the one they found most natural. Until I get that done, I will proudly point to Tim Lookingbill (post #4) who picked the same image as I did even if he was not at the scene.
Good light - and true color :-)
