<p>Hi,<br />recently I decided to do some Lambda prints on Fuji Crystal DP II through WhiteWall.<br />They ask to submit files in sRGB and I'm a little puzzled:<br />since the gamut of this machine+paper is bigger than sRGB, am I loosing part of the colours ?<br />I wrote them an email asking why wouldn't it be better if I send them a file converted to the paper profile<br />(embedding the profile too) and got this reply:<br /><br />"We can accept any RGB or CMYK color space, but if no ICC profile is embedded we will asume it is sRGB.<br />We do not advice you to use our ICC profiles as the colour space, the conversion to the destination output should be done by us to maximize image quality. The ICC profiles we provide are suitable for softproofing, but your file should not be converted to it's colour space. if you prefer a large Gamut working space Adobe RGB is a better option, but you must make sure the ICC profile is embedded so it is treated as Adobe RGB, not sRGB."<br /><br />Why converting to a narrower gamut in the first place ? (AdobeRGB is slightly narrower in places compared to the paper profile of the Fuji Crystal DP II that they provide for soft proof).<br /><br />Wouldn't it be better sending a file in its working space (ProPhoto in my case) and let them do the conversion ?<br /><br />Your thoughts ?<br />Thanks,<br />Giovanni.<br /><br /></p>
