My Name is Nathan Gaydhani, I recently joined the list, I am a digital artist and retoucher. �Hello Nathan. I think it is also important to bear in mind the use of working in different colour spaces. As has been said, monitors are capable of reproducing CMYK colour very well which is good if we want to be able to get as close as we can to our printed work on screen. However the default space for images coming in from cameras and scanners is RGB as the sensors in these devices measure the primary colours of light (Red, Green, Blue), although it is possible to scan straight into a CMYK format. �Possible to convert and save in CMYK, not possible to scan in CMYK as nobody makes CMYK scanners. When I am manipulating images, I want to work in the largest colour space I can until I am happy with the result. I am likely to keep changing an image and it's colours many times and would not want to be limited by the CMYK colours until as late in the process as possible. As we all know there are many RGB colours that cannot be reproduced in CMYK but they can be seen on a monitor. This means that we can work with as much information as possible and then window the best CMYK colours when we are ready to print. �Best to work in a capture colourspace suitable for the subject matter being recorded. For example sRGB colourspace is the default colourspace for the web....and records white/pink/yellow/red/black/brown skintones incredibly well for - most purposes. Another extreme is Joseph Holmes 'Ektaspace' which he created for scanning his awesome 6 bath dip and dunk 5x4in E6 trannies - which is not very good for skintones but brilliant for extreme landscapes. For specific needs, the fact that CMYK gives us the use of black as well, it is true we can create tones in CMYK that we cannot in RGB. Indeed there are also some colours that can only be achieved in CMYK and not in RGB (Browns & turquoises etc) but these represent a far smaller proportion than the extra information that can exist in an RGB colour space. �Which leads me to suggest that relatively few photographers understand colour harmony, due to never having any hands-on experience with painting using pigments on canvas or paper. I would welcome any thoughts by people that disagree, �You give the impression that you know your stuff, so why disagree? <G> William Curwen PS: switch off your HTML please =============================================================== GO TO http://www.prodig.org for ~ GUIDELINES ~ un/SUBSCRIBING ~ ITEMS for SALE
