Dear Robert, > I was referring to having to convert from sRGB, AdobeRGB or ProPhotoRGB to > one's working space of choice Not sure I agree because I do not like "blind" conversions, that is without any control over gamut mapping. Since the internal working space of ACR and LR is based on ProPhoto primaries I think it is better to leave the output as ProPhoto. -- Best regards, Iliah Borg LibRaw, LLC www.libraw.com www.rawdigger.com
