[Award Winner] Making planets, moons, and suns in Photoshop

[bryguy]

I wish there were some sort of "Translate Photoshop Lighting Effects to GIMP Lighting Effects" chart somewhere. Other than that, the Select > Color Range is the only thing that strikes me as an immediate problem.

Haven't had much time to play around with the concepts though and really I am a GIMP neophyte. I'm sure Bryguy or RobA would have those answers readily available.

there is actually a tool like Select > Color Range in GIMP. Just, GIMP calls it Select by Color. In the toolbox, its looks like a hand pointing at a red cube, with a blue cube above the red and a green cube below it. Only thing is you cant do the fuzziness of 200 thing


Ive been busy so I havent really had time to modify this for GIMP, although modifying the earthlike planet for gimp wont be that hard, as just before this came out I figured out how to do the same sort of thing

I thought that might be the same kind of thing, but I wasn't sure. Especially since there is no fuzziness setting. I'm sure there is a way to fake it. Problem is my Google-Fu has been weak in regards to finding stuff about translating PS to GIMP.

Hey I understand. One of the reasons I had to leave my latest WIP as my entry for this months challenge is because of business. I was playing around with trying different things and I have to say that the GIMP lighting effects can come up with some interesting results. Namely when you add bump maps with them. But that is aside from this tutorial. I will continue to try and see what I can come up with.

My guess that the equivalent to fuzziness is either the Threshold slider (which controls the amount of matching colour to select) or the Radius (when feather edges is selected - that controls the feathering of the selection)


What does the fuzziness setting actually change in PS?

Well I use it mostly when doing the clouds stuff in B/W so when I Select > Color Range then use black as the color choice...the Fuzziness also selects all other colors visible within 200 (something) of solid black. This, then, selects all of the darker grays and some of the medium grays (but not all the way up to 50% gray).

I'm guessing that the 200 something is a range 200 above and below the color code hexadecimal. So if there are other colors showing, say greens and blues, some of those might get selected as well, given they are dark enough. So when using Fuzzy Selecting with colors you have to set the Fuzziness down to avoid including things you don't want.

What would really be useful is a map of the color code hexadecimals That way I could test it out for accuracy.
