Dear Alex, thanks a lot for the informative website! I found under math->Some Common RGB Working Space Matrices the conversion matrix for ECI, but I think is version 1 of the profile. I wonder if there is anything released officially by ECI as Adobe did... Thanks a lot for your help!

Go to the http://www.brucelindbloom.com/ (Click Info button, then RGB Working Space Information ) I'm pretty sure you'll find what you need. 🙂 Best from France.

I am deciding which color space to use for the master files of the digitized manuscripts. I am trying to decide between Adobe 1998 and eciRGB_v2. I would like to use eciRGB_v2 but I can't find the specification of eciRGB_v2 on ECI website, in particular how to convert RGB to normalized XYZ values, while the specification of Adobe 1998 is available online and seems more documented regarding these aspects. I would like to ask you if eciRGB_v2 specifications are available for free? And if there are any documents or guideline for the adoption of the eciRGB_v2 in artwork digitalization projects? Thanks a lot! Best regards, Giacomo Marchioro

Good morning Giacomo, Your request is far from my everyday work and my skills to, to be honest. Anyhow, you certainly could send your question to a friend of mine. Please send a private message to Philippe Colantoni (philippe.colantoni(a)univ-st-etienne.fr) from the Jean Monnet University. I'm quite sure he's the right man at the right place to answer your concerns. My two cents. Take care. Best.

Thank you for your reply! I also would like to use this profile in particular for the red tones which are very important for rendering some inks of the manuscripts. For assigning the profile I will probably use Capture One for the conversion. At the moment I am trying to implement the workflow using Python programming language and especially the conversion from eciRGB_v2 to XYZ and then to Lab. This because, after the acquisition and the production of the master, I will perform also a quality assurance step using in scene reference targets for computing CIE deltaE. With Adobe 1998 was easy given the following document https://www.adobe.com/digitalimag/pdfs/AdobeRGB1998.pdf Adobe RGB (1998) Color Image Encoding<https://www.adobe.com/digitalimag/pdfs/AdobeRGB1998.pdf> A Adobe RGB (1998) Color Image Encoding Adobe RGB (1998) Color Image Encoding May 2005 Page 4 Introduction The Adobe® RGB (1998) color image encoding is defined by Adobe Systems to meet the demands for www.adobe.com I can't find a document like this for eciRGB_v2 online and this is a crucial factor for me.
