Also,needs IMPROVEMENT...

Try using the 'smudge' and 'convolve' tool in Gimp. That is how I made these three swirly gas giants

I can??t understand whay you mean by "convolve".I??m using Photoshop in my native language,and not Gimp.
However,I did some work in the original texture and create 2 versions of HD 189733b:

Which one do you prefer?

Did you ever consider typing the words "what does convolve mean" into a certain site known as google?

Needless, just type "define: colvolve" in Google's search bar ->


Google knows all o_O.
Edit: Be sure to make "define" all lower case, or else it will not conduct the search.

I used the tools and these are the curious results:

Unfourtanetelly,it lacks authenticity,bacause I create from nowhere.But it??s interesting.Which one do you prefer?

The second one. Good start Daniel. If I might make a suggestion, you might mute the tones down. In Photoshop, bring the saturation down.

Hey, those look pretty damned good for a complete beginner.

I'm with Buggs though. The second one meets more my expectations
of what a giant gaseous planet "might" look like.

Good job there Daniel. You're coming along nicely now. Maybe I should
have Selden and the Good Doctor yell at me for a while.

Might improve my attitude somewhat.

Number 2.

Sorry,The "versions" are the SAME planet.I was talking about previous versions I made:

This huge spot is based in a infrared map of HD 189733b.See here:

This is NOT a generic gas giant!Maybe the spot is a little too big...

If it represents HD 189733b then the spot might not be too big, but using a 'smudge' tool or whatever the equivalent is in Photoshop it could be made a lot more realistic.

Of course realistic is a relative term here, as no-one has seen this kind of feature in detail yet.

I couldn??t make the spot smaller,but I did some modifications:

Since the gas giant is very near the star,I can imagine it with its bands disturbed and distorced by the star??s gravity.Even the spot shouldn??t be perfect circular.But anyway,it??s an amteur work and for now,I will not be working in it for a while.But it was pretty fun.Feel free to modify the texture.If you want,I can send the texture by email...
