If you have to convert then you probably won't notice any loss of quality, as long as you specify the correct colour spaces :) Use the embedded profile if there is one. I always convert to my Photoshop working colour space. And would sRBG on a camera be the same as sRBG in a Photoshop? It should be... sRGB is a standard. IEC61966-2.1. I've compared that with a generic sRGB profile and they match pretty much exactly (it was a visual comparison of a 3D gamut plot). (Hope that's the right color space acronym.) Is it standardized enough to be the same? Or about the same? You got it close enough. I would hope that if someone labels their colour space as sRGB then that's what it is. Colour management is difficult enough without the vendors getting creative with specifications. - Dave (who's about to find out if he needs to buy a dedicated monitor for his PC, for colour consistency) http://www.digistar.com/~dmann/
Re: Ignoring:PS colour -3 choices ?
not necessary. it is necessay to enable color management by having a chosen working space in Photoshop and converting everything that is tagged with a known color space to that one on input. if a file isn't tagged with a color space and it's from a digital camera, you can assume that it is sRGB. sRGB is an IEC standard. the different types of sRGB given by a camera are to tell it how to modify the captured color before saving in sRGB in the file on the memory card. if your camera supports it, Adobe RGB is a wider gamut color space and gives better results when printing although it looks flatter on the screen. if this is the case, your working space in Photoshop should be Adobe RGB. if it isn't your working space should be sRGB. one of the problems with Paintshop Pro is that ir assumes sRGB and provides no means to map from anything else to sRGB. another is that it provides no means to perform even a rough calibration of your monitor. if you can calibrate your monitor independently of Paintshop Pro, it can do proper color management on printing. Photoshop Elements and Picture Window Pro are two of the lower end programs that do adequate color management for display while you are working.

Are there any good detailed reference texts on color management that you would recommend. Thanks in advance.

RE: Ignoring:PS colour -3 choices ?
I have this on order at the moment based on the Luminous Landscape recommendation: An excellent new book has just crossed my desk. It's Tim Grey's Color Confidence - The Digital Photographer's Guide to Color Management. It is clearly written. beautifully illustrated and contains everything that a photographer needs to know about this oft-times confusing subject. http://www.amazon.com/exec/obidos/ASIN/0782143164/qid%3D1079646139/sr%3D 2-1/ref%3Dsr%5F2%5F1/104-3772011-2039149 Don't know if anyone knows any others... -Original Message- From: Otis Wright [mailto:[EMAIL PROTECTED] Sent: 02 April 2004 14:47 To: [EMAIL PROTECTED] Subject: Re: Ignoring:PS colour -3 choices ?

Color management is supposed to help manage different devices, if the color spaces of your scanner, monitor and printer have the same calibrated color space what you see on your monitor will closely approximate what comes out of the printer.

I quickly opened a couple of image but could not see any real difference opening them in Adobe 1998 or do not color manage. I didn't try printing any to see if there was a difference there.

Re: Ignoring:PS colour -3 choices ?
The differences are sometimes subtle, and sometime more obvious. Use the color picker to see the differences that may be lost by monitor calibration, room light/reflections, and the vagaries of our vision.
