The ICC meeting from 30th January to 1th February was again a great chance to meet with colour management people in person. The meeting was hosted in Munich at Adobe with a great view over the snowy city. I joined the sessions under the OpenICC umbrella to represent the open source community.
Of course many talks went over various specification topics and coordination with other standard bodies and groups of interest in colour exchange. But as ICC is evolving, there are new topics coming up as well.
Notably, ICC is slowly moving from a solely static colour content description of what colours are. There is great interest to cover as well the process of applying colour conversions. This covers necessarily definition of terms and workflows and gets to the questions of why, how and who handles colour. This will help users to do high level decisions as opposed to the current need to understand low level technical ICC terms and figuring out how that applies to actual used implementations.
I presented my work inside OpenICC to add monitor identification and calibration state information inside ICC profiles to streamline profile distribution and installation. The concept found support and the presentation about the meta tag keys came along nicely.
ICC members dive currently into spectral imaging, which is prototyped in SampleICC. I appreciate this direction, as it very likely simplifies the use of spectral readings for colour calculations in applications.
The only discussed hint to reduce the size of n-channel profiles, was work on how to put formulas inside the colour processing pipe. It would be great if that comes to a useful result. Formulas inside ICC profiles where first introduced during the v4 specification but only apply to single channels. For per channel operations are currently some few formulas supported. However the new approach allows to express with more elementary operations and allows free access to all channels.
Obviously many members have a strong background in printing, which is greatly reflected in the spec. But some companies have a strong relation to various imaging industries, like camera manufacturers, who as well create printing or displaying devices. There is potential, that ICC will support their interests, provided they actively contribute. For instance ICC profile embedding inside images is well covered inside the ICC spec. That was a good base for e.g. the W3C to introduce colour management for photography on the net. There is no equivalent to movie or video content. In parts embedding of ICC profiles there does not even exist.
Altogether, the ICC meeting was a great chance to coordinate and intensify the work of ICC and OpenICC.
