I'm afraid that I am in the center of the debate. Unlike theory guys like Chris I focus 100% in the field since pre photoshop days. My specialty is digital photography whereas many color specialists  came from a DTP and prepress background, my color management experience has always been from digital input to output. Of all of the customer problems that I face on a daily basis #1 would have to be the very antiquated idea of gamma. Users are not stupid, but the industry treats them as such by avoiding the fact that that all computer displays can be configured to the same standards, and frankly L* is the most agnostic approach as it is based on human tonal perception. The ECI adoption of the L* based working space has an impact that makes digital capture crystal clear. 50L=128. Ask 100 photographers to photograph a gray card today using three of the leading image processing apps and you will get completely random results. Why? the industry has allowed itself to run out of control when it comes to standard practices. Each tool presents the user with different gamma gradations,rgb readouts, percentage readouts, and none are documented.<br class="webkit-block-placeholder"></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>The L* and ISO standards are going to prove to be critical for digital imaging to mature. Chris is correct in that in a 16 bit workflow ICC takes care of the gamma mess, but he fails to understand the bigger picture. Not everyone wants of needs to have a color consultant to have a repeatable process, or to go to a photo lab or printer and expect a consistent result. For my worldwide museum clients it is absolutely essential that ISO standards can help preserve cultural history for future generations. Right now, legacy shortcomings in the imaging field are being propped up by ICC alone. As a supposed scientist Chris is incredibly closed minded on this topic, but I don't know why.<br class="webkit-block-placeholder"></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>I recently posted an article that actually laid out very a very specific international case study comparing calibrated digital captures processed to AdobeRGB, ProPhotoRGB, eciRGBv2, and ProStarRGB (a proposed wide gamut RGB space with L* TRC-it's literally ProPhotoRGB modified to L*) Chris has seen this document, so I don't know why he can say that no one has tested it. By the way, the results on screen and in print are better! Chris and a select group of "color experts" have personally attacked this article which was only presented as a field test of existing and proposed standards. The intent of my article was to encourage thoughtful discussion, and frankly to push Adobe and camera manufacturers to get behind ISO standards. The statement that Chris made regarding ISO standards should "Just Die" are incredibly short sighted and unprofessional.<br class="webkit-block-placeholder"></div><div><br class="webkit-block-placeholder"></div><div>Anyway, please feel free to post this up to the ECI board or anywhere else.</div><div><br class="webkit-block-placeholder"></div><div>You can download the article from our web site: <a href="http://www.cdiny.com">www.cdiny.com</a> the article is called "<span class="Apple-style-span" style="font-size: 16px; "><b>Adopting ISO Standards for Museum Imaging"</b><span style="font: 12.0px Helvetica"> </span></span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 10px/normal Helvetica; "><br class="webkit-block-placeholder"></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 10px/normal Helvetica; ">Thanks,</div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 10px/normal Helvetica; "><br class="webkit-block-placeholder"></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 10px/normal Helvetica; ">Scott Geffert, Center for Digital Imaging, Inc. 1/2008<span style="font: 12.0px Helvetica"> </span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 10px/normal Helvetica; "><font class="Apple-style-span" size="3"><span class="Apple-style-span" style="font-size: 12px;"><br class="webkit-block-placeholder"></span></font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 10px/normal Helvetica; "><font class="Apple-style-span" size="3"><span class="Apple-style-span" style="font-size: 12px;"><br></span></font></div></body></html>
