Re: 18% grey
Re: 18% grey
Life is full of compromises, isn't it? I personally don't endorse AdobeRGB because of its lack of red, yellow and green saturated detail. On the other hand, it is a Photoshop color settings preset which many people use. For sake of providing a recognizable standard, you can certainly do the 54s with AdobeRGB.
From a photographer's perspective, 2.46 = Kodachrome/Ektachrome/Fujichrome contrast. I have a working space which captures the range of color and detail, while preserving the film contrast. Once the input profile has been converted to this space, preparing the image for output is the next concern.
As a drum scanner operator and a photo darkroom guy, I recognized that there are perhaps 3 kinds of shooters in the world:
1) Commercial/Table top
2) Fashion/MakeUp
3) Portrait
As a general rule, Photog 1) likes gamma 2.2; Photo 2) likes 2.0 and Photog 3) prefers a gamma of 1.8
To solve the problem I have a matched set of spaces which reduces contrast from 2.46 (much the same way that masking for Ciba/Ilfochrome or interneg used to work. This is the well known problem of how to get big dynamic range info into short dynamic range prints.
Please contact me off list if you think that this might be of interest.

Thank you for your answer. By placing 18% grey at L*50 in a 2.4 space is it your understanding that 2.4 gamma has special importance? Since the same logic would place 18% grey at L*54 in a 2.2 space and 18% grey at L*61 in a 1.8 space.
Do you think ths means that I should continue to target L*54 if I am selecting Adobe RGB 1998 as an output profile space in Camera Raw because it has a gamma of 2.2?
