How do people do adjustment layers in GIMP?
Do you duplicate your layer, and then hit it with the adjustment? say layers, or curves?
I'm not sure about the best way to do it, and I'm teaching a class where we'll be using GIMP(cuz its free), not Photoshop, which I'm used to.
last time I checked, adjustment layers were copyrighted by adobe, not publicly available for other developers. Not even open source ones.
An adjustment layer is a layer which contains no actual pixels. If you duplicate a layer, you have a pretty normal layer. Decreasing the opacity can give you some freedom, as will changing the layer modes, but the adjustment layer itself is adobe's baby.
I asked a developer for Conduits Pocket Artist 3.1 about this as their PPC software allows for layers. Sadly this is what she told me.
As you seem to know, Gimp doesn't have adjustment layers; my workflow (especially when I'm unsure of the effect I'm going to get) is to always duplicate a layer before I edit it. It's hard on memory, but it allows me to compare edited to unedited, and often saves me from badly overdoing an effect. I also always keep an untouched original as the bottom layer.
I also increase the undo history size; it sucks to not be able to back up after a lot of d&b, say.

Off track here, but Corel PSP XI does have adjustment layers and they go by that name.
ED: So I don't think adobe has exclusive rights to the term/technology (didn't mean for that to sound mean or anything)
Back to your regularly scheduled program.
I played with the GIMP but really didn't get in to the layer thing at that time...sorry no help here.
so, eamurdock--
do you do both levels and curves adjustment on your duplicate layer? or do you say, do levels, duplicate that, and then curves?
Gimp is powerful, and good software, but when you get used to a few really easy things in Photoshop it can really throw you for a loop.
Welllll.... I usually just do curves ;) But seriously, I duplicate anytime I feel like I'm at a point I might like to get back to; like saving a video game. Usually not more than 5 times in an image (assuming I'm not doing spot editing or other layer-intensive work).
Of course, this plays heck with the use of layer transparancy and such, so the downside is that if you come up with an effect you like using multiple layers you generally have to merge them before you move on.
I'd love to have photoshop - but I'd love a lot of things.

But those are just ordinary layers... you can't do that in baisc, can you?
