Due to the fact that most people are taught only simple concepts to do with a subjective concept like colour or colour analysis it can be difficult and confusing for people to discuss this kind of issue. To get to be a professional photographer I had to take written exams which were all about colorimetry (Things like degrees kelvin and mired values and colour balance) and sensitometric analysis of (old fashioned) colour film emulsions.... http://www.springerlink.com/content/w8j53q7180mn9226/ Since then I have taken a few degrees in pure sciences. The clever bit comes when you finally match up sensitometric analysis and colorimetric related issues to your own subjective understanding of colour (color if you were trained by Kodak). Most people can only manage to do this effectively (numerically as well as subjectively) after many years of working as a photographer or through the process of paint matching. I find that while my own eyesight isn't very good due to having my face crushed when I was a child but in actual fact my eyesight is very good at judging colour balance which is a skill which was essential in old fashioned colour print production. Some people have brilliant eyesight but rotten colour judgement. Vision and the optical nerve is a very long and tortuous subject to understand :) Richard www.sheflug.org.uk -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
