Hello to all,<br>
Working with wide Gamut Images makes oonly sense with 16 Bit data. <br>
<br>
In this case the question of Gamma 1,8 2,2 sRGB or L* is not
problem. ProPhoto RGB standardized through ISO and Thousand users of
Adobe Photoshop and Lightroom working with is successfully as an
intermediate step between vendor specific RAW and outputspaces like
e.g. sRGB.<br>
<br>
I don´t see the need that the Open Source Community would need an
extra wide gamut space.<br>
<br>
Best regards<br>

some software projects want to preserve wide gamut data like
originating from cameraRAW. ProPhotoRGB, which's gamut appears
quite reasonable,
<br>
specifies unfortunately a gamma of 1.8, which is not good for
2.2/sRGB style display systems. Ideally we find a colour space to
use as a intermediate space for displaying and storage for
inclusion into the OpenICC profile collection.
<br>
<br>
I created a editing profile with gamma of CIE*L following the
ECIv2/LStar-RGB profile and used the wide gamut colour primaries
of ProPhotoRGB alias ROMM [1].
<br>
<br>
Please find the new profile attached for review and comments.
<br>
In case you know a freely distributable existing alternative or
like to create one, that would be welcome as well.
<br>
<br>
<br>
kind regards
<br>
