<p>More “real world” sRGB at the photo lab…<br /><br />Many know that sRGB is a so-called standard profile for computers monitors. The monitors are emissive devices. The Type C photo paper is reflective. Not really a fair comparison. <br /><br />A more fair comparison could be a Type C translucent clear (DuraClear) or milky-back (DuraTrans) print film. At least the film in its lightbox would be somewhat emissive but even then, the photo dyes are just very different than phosphors, LCDs, LEDs, etc. <br /><br />The Type C paper print fails especially in the bright colors of sRGB as seen on-screen by photographers and graphic designers. Again, very misleading for a lab to say “sRGB is the goods.” Their output profile is “the goods” and unfortunately, that’s as good as it gets. The photo paper simply will not reproduce some of those bright sRGB colors. The photo emulsion dyes have a lower gamut in those areas. <br /><br />Regardless if you begin your file editing process with a wide gamut such as ProPhoto and soft proofing with the best Type C output profile, many bright colors could be reduced to a disappointing lower gamut. However, again, Type C from sRGB, Adobe98, or ProPhoto works great 90% + of the time, and again, by using Perceptual intent to preserve details. Experienced photographers and graphic professionals know their tools and the limitations of their resources. The photo lab profile for soft proofing is the tool to show the limitation of the resource. <br /><br />1) In the 1990’s the “common” interface between photo printer engineers, customers, sales, etc., was the PC monitor. <br /><br />2) In the 1990’s the photo printers were delivered to market just as sRGB was believed to be the “standard.”<br /><br />3) In the 1990’s photo labs were told by the photo printer manufactures to use sRGB. <br /><br />4) In the 1990’s some Photoshop users needed an expensive plugin from Kodak to soft proof. (PS 6 made things better.) When did PS 6 arrive? <br /><br />5) In the 1990’s LaserDiscs had a better picture than the suboptimal VHS, just not as practical as it turns out. <br /><br />I hope this helps. <br /><br />Question(s) for Andrew: <br />With your color tools, can you count how many colors are in the two given spaces of sRGB and any Costco Type C profile?<br />From the difference, can you imaging which group(s) of those colors are the most problematic in reproduction? </p>
