2004年2月16日 · It takes an associated color space to give them meaning. Without a color space all you have is RGB or CMYK mystery meat. A LAB value, by contrast, correlates to an exact spectral color. Working in LAB is counterintuitive at best. All the brightness information is in the L channel while color is encoded in the a and b channels.

2010年7月12日 · It is the only color space setting in Vuescan with which Display color space is ignored, because no conversion is done, only assignment.<br> <br />2. Even with this color space, the RAW scan is not equal to the regular scan, but if one applies a curve with only one node (in:163, out:94) to the regular scan it becomes equal to the raw scan.

2007年2月15日 · RAW has no inherent color space. Only when you convert and output a file to you define the color space for the output file. In terms of sRBG vs. Adobe RGB (aRGB) there are issues beyond the size of the two color spaces. The way that Nikon implements the two color spaces results in aRGB being more accurate than sRGB.

2007年2月2日 · For example, the Photoshop working space Adobe RGB (1998) is based on a color temperature of 6500K and a gamma of 2.2; if the monitor is calibrated/profiled to 5000K, gamma 1.8, then Photoshop is supposed to convert the image file to a color temperature of 5000K, a gamma of 1.8 and the calibrated black and white points.

2004年3月6日 · sRGB is a basic color space - the standard by which images are stored in file form. Other color spaces include Adobe RGB (1998) and LAB. Adobe RGB has a wider gamut (range of colors represented) than sRGB, and is widely used in part because it is a reasonably close fit with printing press requirements. sRGB has approximately the same gamut ...

The landscape itself is transformed within the color space (the human vision). This is done in such a way, as to NOT CHANGE its appearance compared to the situation when the filter was in front of the lens.

2010年1月9日 · Its a synthetic color space built with simple math used for editing images (its a working space, a Quasi-Device Independent editing space). The display is an output device. <br> The reason I sent you to the URL is to understand the role of working spaces and how they are completely divorced from the display.
