According to what I've read on the Epson list, sRGB was a gamut designed around an average computer screen. Most people with filmscanners probably have better screens which are capable of a wider gamut. Having said that, if the monitor profile is the Windows defaut, not one specifically for the monitor, AFAIK it will be sRGB regardless of whether the monitor is capable of more. and then of necessity alter the non-viewable colours so that they are viewable, to the closest color displayable by the monitor. You will get an impression of what the result will be - you will not see the actual result until it is printed to paper, film, or whatever. And only then if the whole system is accurately profiled. Otherwise you'll see *a* result but not what you might expect. Photoshop et.al., when showing color in another color space, will show you how the colors relate to, or compare to each other, in that color space, even though all of the colors in that color space are not viewable onscreen. Hm. I'm not really sure how it does that, but I follow what you're suggesting above about compressing the gamut to fit. Photoshop 5.5 has an out of gamut display but I'm unconvinced about its usefulness. In the absence of expensive hardware and software to accurately profile my whole setup, I'm beginning to think that sticking to sRGB is probably the simplest way out. Rob

Yes, for the web. But what about for print? My understanding is that colors outside of the sRGB gamut are printable, primarily cyans. My method, then, is to use Adobe or Bruce RGB for working with the image, then archive without any embedded color space, but convert to sRGB for posting on the web.

Surely you should archive with the correct profile where it is known. You can always ignore it later, but if you don't know what it is to start with you can never get the exact archive image back.

Re: filmscanners: Re: filmscanners: Does CMM work on Win2000?
Qualification first - I don't know for a fact that only colors strictly within the sRGB gamut can be displayed, but that is generally the case. Answer to the question - Photoshop cannot display those colours. A monitor cannot display colours that it cannot display. What Photoshop and similar programs do for non-sRGB colour gamuts is to alter the viewable colours so that they coincide with what the output (print, film, etc.) will be like, and then of necessity alter the non-viewable colours so that they are viewable, to the closest color displayable by the monitor. You will get an impression of what the result will be - you will not see the actual result until it is printed to paper, film, or whatever. Photoshop et.al., when showing color in another color space, will show you how the colors relate to, or compare to each other, in that color space, even though all of the colors in that color space are not viewable onscreen.

The tag is only used if the software is aware of it. Windows ignores embedded profiles AFAIK. As I think Maris suggested, you'd need to convert the image to sRGB in Photoshop then save it as a different name before using the new file for wallpaper. Otherwise Windows will interpret the RGB values as sRGB and they will look flat. Rob Rob Geraghty [EMAIL PROTECTED] http://wordweb.com
