Wayne, I don't suppose clipboard formats (on PC and Mac) are smart enough to have a field for "color space"? Clipboards can hold text or images. / Roger -----Original Message----- From: Wayne Bretl via colorsync-users <colorsync-users@lists.apple.com> Sent: Wednesday, May 6, 2020 11:04 PM To: 'Jeff Nova' <jnova@colorhythm.com>; colorsync-users@lists.apple.com Subject: RE: Lab -> RGB Well, one good thing came out of this - I did a quick test with Chrome on my Windows 10 PC, moving an sRGB web image (viewed on Flickr in Chrome) between my sRGB monitor and wide gamut monitor, and the color management is working. I have no idea when this started to be the case. On the other hand, color management also works in Photoshop when I move a window from one monitor to the other. On the third hand, Photoshop does not recognize that the image, copied from Flickr to the clipboard, is sRGB and ask what I want to do when I open a new file and paste in Photoshop; it instead applies my default working space. I have to assign sRGB manually. It appears the color space info is lost in the Clipboard app. Normally, photos from (some) other sources will be recognized as not In the default space, and Photoshop will ask which space to use. So, I will still watch my step, as some pitfalls in color management have not been fixed. -----Original Message----- From: Wayne Bretl via colorsync-users <colorsync-users@lists.apple.com> Sent: Wednesday, May 06, 2020 6:07 PM To: 'Jeff Nova' <jnova@colorhythm.com>; colorsync-users@lists.apple.com Subject: RE: Lab -> RGB Please clarify "web application." Is it going to display in a web browser? Many web browsers are not color managed and will ignore color space information, and assume the color space is sRGB. -----Original Message----- From: Jeff Nova via colorsync-users <colorsync-users@lists.apple.com> Sent: Wednesday, May 06, 2020 5:01 PM To: colorsync-users@lists.apple.com Subject: Lab -> RGB Hi friends, We have a web application and want to display the best previews we can for Lab images, which are not supported by any browser. The Lab we expect is the default Lab from Photoshop, which I think is D50. So, what is the best choice for RGB space? We are tagging the files, and prefer v2 profiles for more browser compatibility, but will do v4 is needed. I don't need help in the transformation - I just want to know the best RGB space to present the widest gamut resembling Lab as possible. I assume one of the best choices is Don's MaxRGB? http://www.hutchcolor.com/profiles.html I welcome any input!
