![]() ![]() Lightroom almost does this with MelissaRGB (it's very hard, but not impossible, to find a color outside of that space). If C1 worked internally in something like DCam 5, why would it clip when converting to (or from) anything? As long as it's always 16 bits/channel, quantization errors are unlikely (and might it be 32 bits/channel, eliminating them entirely)? That would more or less allow it to claim to be space-neutral internally - it imports images in in the camera space, displays them in monitor space, exports in a selected export space and prints in printer space, all of which fit within the huge internal space. That could even be outside of DCam 5, but since we can't see it or print it, why worry about it unless you are hanging a show in an apiary. Can a flower display colors outside of ProPhoto to a bee? Almost for sure - some flowers reflect UV, and bees can see it. Can some weird, reflective color we see on occasion (a brand-new traffic cone?) get outside of ProPhoto? I don't know. Some monitors CAN display a few colors outside of Adobe RGB, and 11-12 ink printers can print substantially outside of Adobe RGB, but neither can hit the edges of ProPhoto. ![]() ![]() No monitor I know of can display any color outside of ProPhoto, and no printer can print one. This example was taken from a P45+ image of an IT-8 test chart with all samples inside Adobe RGB and processed with Capture One v7 without any colour editing.Ĭould the internal color space be so large as to fully contain all supported input and output color spaces? Realistically, a color space only a little larger than ProPhoto should do this - very little of value is outside ProPhoto, although Joseph Holmes' DCam 5 is even larger, and is supposed to fully encompass human vision. I have actually observed this in one of my experiments with C1, it pushes deep blues that are perfectly inside Adobe RGB wide outside Adobe RGB, causing a large colour reproduction error although it is not visible on a screen with Adobe RGB as it is clipped to Adobe RGB in visualisation. Those are colours that cannot be represented by any output device? Also the colours cannot be observed as the display will clip them. To make a fine point, what is the benefit of the advanced colour editor pushing colours outside the colour gamut of any monitor or any printing device. What this means is that every color that can be reflected by the surface of an object of any material is inside the Pointer’s gamut." "The Pointer’s gamut is (an approximation of) the gamut of real surface colors as can be seen by the human eye, based on the research by Michael R. I have rechecked and it is clear that ProPhoto RGB does indeed not cover all visible colours, but it nicely encloses a colour space called Pointer's Gamut. ![]()
