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.

Ive been busy so I havent really had time to modify this for 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?

Having used both programs I would say that the Threshold slider is the equivalent to Fuzziness.

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.

yea i have have the cs4 trial, and so i brought up both gimp and cs4 and tried it out on both, and threshold is the best you can do for it. I would say set the threshold to about 50-100, because most anything higher than that selects almost the entire image.

hmm, after experimenting all day, i cant seem to figure out a good way to make a sun :(



oh well, i was bored and made myself a planet tho :)


p.s. I just love my clouds :) dont know why, but i do :)

The clouds are awesome. Cool pic.

Wow. Just wow. Awesome tutorial. I repped you for it - well deserved.

Once I have a decent world map to start with, I'm SO making a planetery view of it. Now to get decent results on my continents...

Playing with your continental tut, and RobA's as well, to see what I like best. It'll come in time. <sigh>

Thanks, mate. Don't push yourself too hard to come up with your own style...mine has taken about 5 years to develop.

Just an update. I went through the tutorial using a combination of Gimp 2.6.2 and Photoshop Elements 2.0. While I wouldn't call the results as "pretty" as Ascension's, I was able to pump out a reasonable barren planet picture.

Thanks Ascension.
