Here, apple's own words, is a description of the mess.



What a mess, indeed. And this is supposed to be pro software? It may not mean much to certain people but seeing how convoluted a workflow this situation makes, I'm wondering what has happened at Apple through all these years of software evolution and ColorSync ubiquity!

There are two sets of distinct problems.

The first : Apple has it's own evolutionary trail. The whole gamma issue was based upon viewing in high luminance conditions. Setting the display to a lower gamma at higher luminances makes a lot of sense. It boosts the shadow detail that is overwhelmed by the flare and at higher luminance levels, scenes appear to have more contrast. This does make sense.

The second issue: Ambient illumination is not static. While the gamma assumption that Apple made was good for the original Mac situated on the kitchen table at noon, it starts to fall apart during the day. When viewed in a dark environment the situation is not good. All major display calibrator vendors (all two of us) are offering some form of ambient correction. It has been well recieved by the consumer, but to be honest, I'm not sure how valid it really is. It certainly improves the viewability of the display at high luminances, but I wouldn't want to be doing screen to print matching with ambient turned on.

As you can see from the apple document, video workflows are very convoluted. The basic ICC workflow is not really suited for video and motion picture, although I will get various levels of disagreement from some folks in the ICC on this point. The entire workflow is tradionally done in an "output referred space". That's why it is very important to stick to the definition of the space.

I've just started working in video editing systems and I am simply amazed at the complexity. The format/codec selection process is staggering and I am now starting to understand the technical landscape. There is a lot of room for mischief here.

Take care,
Tom
