Without trying to be rude I think maybe you should do a bit more study. Two images with different color spaces appropriately processed for web display should not vary significantly in saturation or colour cast. Also when making any type of semi-critical colour comparison it really does help matters to have be using a similar or the same subject in the same light. Firstly there is little point in displaying images on the web in other than sRGB colour space as at least 99% of web browsers (anyone can make up stats :-) are not colour space aware so will not render the images correctly. Secondly most images presented for web display have the colour tag information stripped so even a colour space aware Browser will generally assume sRGB rendering (depending its colour space management policies) Just to highlight my point in the case of your two images only the AdobeRGB image has an embedded color space tag. Viewers should only be able to potentially "see" a difference between (like) images when they are displayed using a media type that has colour gamut than can take advantage of the extra colour information. A typical video display (which typically approximates the sRGB gamut) isn't a good tool on which to make comparisons or draw conclusions. All that said if you intend your final output to be to print and the printer can take advantage of the AdobeRGB colour space then using AdobeRGB probably isn't a bad idea but you need to really shouldn't be seeing a difference on screen if your editing work flow and image colour space handling is being managed correctly. -- Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://home.swiftdsl.com.au/~distudio//publications/ Pentax user since 1986, PDMLer since 1998 -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
