|DCam 1 Example
|The colors of this digital snapshot readily fit within the very small gamut of DCam 1, because the image has both neutral highlights (the clouds) and reasonably neutral shadows. The version you see here has had a +20 chroma variant applied after RAW conversion and still the clipping amounts to only a few pixels in the medium shadows. Even much larger chroma increases were feasible without noticeably harmful clipping.
Were the lighter tones in this image very colorful at all, DCam 1 would probably not hold them. Each working space, in a Yxy plot, resembles a triangular tent with vertical walls and a roof that somewhat resembles a three-sided pyramid. The larger gamuts have the three corners of the tent further out, but they also have roofs which slope away from the hight point, the white, at lower and lower slopes as the corners move out. A small space like DCam 1 is especially lacking in headroom, and most acutely on the warm side of white.
In contrast, DCam 5 has so much headroom that RAW conversions rarely need the extra room that it has, compared with DCam 4, if any care is exercised during RAW conversion. Still DCam 5 could be useful for automated RAW conversions, to avoid essentially 100 percent of clipping at that point, keeping in mind that as you give yourself more room, you increase quantization proportionately.
