:::::::That does not make any sense, sorry. --[[User:Dmitry-kazakov|Dmitry-kazakov]] 17:39, 23 January 2009 (UTC)
::::::::These facts make perfect sense to anybody who has even basic knowledge about computers. Obviously you are not one of them. May I suggest that you get one of those "Computers for dummies" books and start learning the basics. --[[User:PauliKL|PauliKL]] 19:45, 25 January 2009 (UTC)
::::::But adding two pixels in non-linear color space does not give correct results. That was my original message. If you are editing an image in an image editor and you want to do it right, you should first convert the image into linear color space. (In case of RGB to grayscale conversion, the image editor probably does the color space conversion automatically.) --[[User:PauliKL|PauliKL]] 11:20, 23 January 2009 (UTC)
:::::::When something does not give correct results, then it is called incorrect. Which in this case is another way to say that it cannot be added, like apples and oranges. See [http://en.wikipedia.org/wiki/Pixel pixel] --[[User:Dmitry-kazakov|Dmitry-kazakov]] 17:39, 23 January 2009 (UTC)
::::::::That is just plain ridiculous. There is no law of nature that would stop people from making mistakes. If there was, accidents would never happen, and for example at school everybody would always get just straight A's. The fact is that it is perfectly possible to perform image editing operations in non-linear color space. And ignorant people like you do that all the time, and therefore get bad results. That is why I gave the advice. --[[User:PauliKL|PauliKL]] 19:45, 25 January 2009 (UTC)
