- Info Strongly oversaturated with very strong contrast enhancement. The histogram speaks for itself. (Original nomination)

- Keep - still good FP -- George Chernilevsky talk 11:39, 24 May 2011 (UTC)

- Keep If ever there was a wow factor, this is it. My mistake was clicking on the histogram link, that hanged my browser up forever. : ) If you ask me, stadiums were meant to be oversaturated. – Kerαunoςcopia◁galaxies 21:42, 24 May 2011 (UTC)
- Keep I like it as it is, but wouldn't be easier to make a version with desaturated colors, than making this colorspace animation? (Which I don't understand, I must admit :) --Lošmi (talk) 08:20, 25 May 2011 (UTC)
- There is no way to fix oversaturation or over/under exposure if the image data is already clipped. You can decrease the saturation, but it doesn't improve the picture. The color information that is lost, is already lost. You will need to invent something new (e.g. new color information), to correct this. No way to go. -- /人◕ ‿‿ ◕人\ 苦情処理係 08:31, 25 May 2011 (UTC) PS: I created the animation some time ago, to show differences between oversaturated and not oversaturated images. Just forgot to nominate this image. -- /人◕ ‿‿ ◕人\ 苦情処理係 08:33, 25 May 2011 (UTC)
- I don't understand what color information is lost, but nevermind. If you think that image can't be improved that's ok. But, I still like it as it is :) --Lošmi (talk) 11:09, 25 May 2011 (UTC)
- I added a little illustration to the right. It shows you what happens when you try restore original colors on an already imperfect source image (top right in both cases). You won't get the original back. You will always get a worser quality as the original could had, if done right. Look at the file description for further details. -- /人◕ ‿‿ ◕人\ 苦情処理係 12:03, 25 May 2011 (UTC)
- Ok, I get what you want to say. But, many of FP images are not straight from camera. They are usually processed − brightnes/contrast, saturation, sharpening, etc. You can't revert to original colors on them as well. I had something like this in mind when I said desaturate. --Lošmi (talk) 13:45, 25 May 2011 (UTC)
- Yes they are. But within the bounds of sRGB or any other color profile. But if you would look at the histogram of this image your will find anything needed to see that it is completely oversaturated. Since we have no original without manipulation we can't recreate the original image. Not worthy to be featured if you ask me.
For further information i appended the histogram as well with the wave form diagram of this image and the desaturated version from Lošmi. If you compare the two wave forms (histogram for each channel and line), then you see, that desaturating the image does not remove the issues. Instead you get blury results due to an additional JPEG compression. The clipping of the color channels remains. -- /人◕ ‿‿ ◕人\ 苦情処理係 14:38, 25 May 2011 (UTC)
