Colour Management Questions!

What is the purpose of colour management ? (http://www.normankoren.com/color_management.html) improve the color match between your monitor and printer. work with fine art papers or nonstandard inks, for example, archival pigment-based inks from independent manufacturers. send out an image to be printed, for example, on a large format LightJet printer. reproduce color as precisely as possible-- for example, for fashion, weddings, or art reproduction.

What problem makes colour management necessary ? (http://www.luminous-landscape.com/tutorials/whats-the-problem.shtml) Printers use densitometers which makes them very inaccurate and they do not measure colour.

What are the components of a device profile (ie what information do they contain) ? (http://www.adobepress.com/articles/article.asp?p=1315593&seqNum=2)

What is the difference between a device profile and a working space ? (http://en.wikipedia.org/wiki/Color_management) and/or (http://www.adobepress.com/articles/article.asp?p=1315593&seqNum=2) A device profile is the settings/colours you makes the screen/device have/use where as a working space can not be changed by you but it is the colour area that you do you work in.

What is a ‘reference colour space’ and how are they used ? Give an example of one. (http://www.cambridgeincolour.com/tutorials/color-spaces.htm)   A ‘Reference colour space’ aims to describe all colors visible to the human eye based upon the average response from a set of people with no vision problems eg standard colorimetric

What is the difference between ‘calibrating’ and ‘profiling’ ? (http://www.adorama.com/alc/article/8525)   Profiling is the product of calibrating. Calibrating brings the system into line and then you save those settings as a profile for future use.

What is a Rendering Intent ? (http://www.cambridgeincolour.com/tutorials/color-space-conversion.htm)   Common rendering intents include: absolute and relative colorimetric, perceptual, and saturation. Each of these types maintains one property of color at the expense of others

Which Rendering Intents are most useful to photographers, and when would you use each of them ? (http://en.wikipedia.org/wiki/Color_management)

In practice, photographers almost always use relative or perceptual intent, as for natural images, absolute causes color cast, while saturation produces unnatural colors.
