p.1 #6 · Are Canon’s Colors Mushy and Nikons Not ? | |
The misconception is often really about what "camera colour" really is... :-) And it's nothing like what you get out of any raw-converter. And most cameras can get "good, roughly accurate" colours out of most scenes with the right camera profile installed.
But there's quite a lot of truth about "Canon having worse colour", and this is not some fanboy propaganda, this is a digital colour signal processing truth. Canon, and Olympus (and in a few examples Pentax too) have got very expanded colour filters on the CFA on the sensor. This is to increase light throughput, and thereby lower picture noise. Unforunately it also lowers colour hue placing precision quite a lot. Both the Canons and the Oly's have quite a lot of points on the hue-curve where they cant fulfill the Luther-Ives condition (two or more colours in front of the camera can under several different lighting conditions result in the same values IN the camera, the raw-file).
The leader in colour precision right now is Sony, with the A850/900 models. Unfortunately for Sony, their lower light-efficiency (that in part stems from having better quality, steeper colour filters!) has given them a bad reputation regarding the high ISO performance, without giving them credit for having the best colour precision and presentation this side of medium format backs.
The problem with the 5D2 is mostly in the greens>reds, where the red colour filter "swings back" in efficiency when it should just fade away - and this into a green that is all to wide to be able to discriminate between the sensitive middle greens.
Consider the graph below. There is NO way that a raw-converter, or ANY kind of NASA/NSA black technology, can ever know if values in the marked area (mid green to yellowish) are either bright mid green or dark yellow green. It's all guesswork. Same goes for quite a lot of the yellow-orange hues, where the 5D2 is to "flat" in the filtering to be able to properly discriminate between yellow-orange and red-orange. This type of filtering is common to all Canons in production today, and give the famous "Canon" skintones.
