Canon EOS-1Ds Mark II Review
Image parameters: Color matrix
Color matrix has a total of seven settings, five presets and two user definable custom matrices (any combination of color space, saturation and color tone). Note that images taken in the Adobe RGB color space have their filename prefixed with an underscore (_) this complies with DCF 2.0 (Exif 2.21). The five preset matrices combinations are show in the table below.
Color matrix presets
|3 High Saturation||sRGB||High||0|
|4 Adobe RGB||Adobe RGB||Standard||0|
|5 Low Saturation||sRGB||Low||0|

Color matrix: Color space
Note that in these samples the Adobe RGB image has not been converted to sRGB and so to view it correctly you will have to load it into a color space aware photo application and assign the Adobe RGB color space. Below each sample is that image's CIE u'v' Color Distribution chart; larger gray triangle approximately represents the range of color which the human eye can resolve, the inner triangle the available gamut in each color space (sRGB or Adobe RGB).
|1 Standard (sRGB)||4 Adobe RGB|
Color matrix: Custom saturation
Saturation adjustment allows you to control the strength of color in the final image. As you can see in the sample below although the Mark II provides a five level adjustment of this parameter the actual effect on color saturation is quite subtle. Each step produces an approximate 5% change in saturation (eg. +2 = +10%).
Color matrix: Custom color tone (hue)
Color tone subtly adjusts the hue ofthe image, a negative setting makes color appear more reddish, a positive setting makes color appear more yellowish. The maximum +/-2 setting equates to a +/-9° hue shift.
|Color tone||25% crop|
