Quote - If you strive for realism, don't go overboard with contrast in gas giant atmospheres.

The pictures people see are the result of image processing which enhances sharply the contrast.

If you have a look through a amateur telescope at Jupiter, you might have troubles even detecting the Red Spot (for a real example, see http://www.youtube.com/watch?v=ExHaVZIeiwo). The images you uploaded look right as they are now.

Thanks for the hint.

Well, its certainly true that Jupiter, seen through an amateur telescope (and the earths atmosphere) will always appear blurry and wont reveal a lot of detail. Hubble shots show a lot more detail because the telecope is  more powerful and it is located outside of the earths athmosphere.

To pick up the example of the gas giant. What you see on the picture I posted is generated by a Metanode with some parameters extracted.
If anyone finds there are too many details he simply decreases the contrast parameter slider.
If he wants to change the hue, the tweaks the hue offset slider. 
As simple as that.

I am heading for realism to a certain degree. Maybe credibility is a better word. I want some elements to be credible enough to create an illusion. 
However realism for the sake of realism is not my thing.
In the context of art, realism is just an asset. Something which artists can use to give their art the appearance of being real.
