Are you sure about that? I use Digikam for library purposes but it has an editor that I don't use and one of the functions is an 8 -16 bit tool as well as a 16 -8. As I said I havn't used it enough to understand it. But given that it is when you start dragging the histogram around that banding issues kick in it makes sense to be able to do slow 16 bit work and then snap back to 8 for nimbler work. Just to be clear an untampered 8 bit image doesn't have visible banding -- it comes in from careless editting.

Actually someone here may be able to answer this - In LR does a jpeg gets processed as 8bit or is it converted to 16 bit for processing?.

+ one for GIMP. It is a brilliant editor that certainly requires a learning curve and it is my editor of choice. But that banding you are describing is a classic example of the dreaded 8bit limitation of Gimp processing. And yes it happens when the contrast is pumped esp after previous colour manipulations. Once you understand it it is easy to control. 8 bit processing makes Gimp the nimble beast it is.

And also it gets confusing the other way round for Raw. For instance I think that if you set a WB and save in raw then that WB is the default opening value in your editor but you can change it at your whim. Or rather change the colour temp and tint. But it is useful to have it opening approximately right given that you have to shuffle the two sliders.

Just thought I would give you your 100th like jono:) But yes you are right -- the image ends up as you want it - it is much more creative.

Yes that would work but if you have those skills to selectively apply the sharpening etc then you probably have the skills to generally exceed the jpg. And see all the settings you have just described -- see my last post about not having to worry about them out in the field under pressure. Look, I get a lot of enjoyment from sitting here at the computer editting my images but that doesn't apply to everyone. So do what suits you - if you have spent all day hunched over a computer at work who can blame you for not wanting to in your own time.

Yes and all you have to do is push the slider a little bit in your Raw editor to achieve that. There is no reason why a jpg algorithm can't do the same -- isn't there a dynamic range setting? But that brings me to another plus for using raw. Things are actually simpler while you are out shooting. Don't worry about your colour temps - DR etc.

In camera jpegs these days are so good it is a challenge to beat them when you start out on the raw path. It is often a good reality check to do Raw+ and see how your effort stacks up. However it is the autosharpening of jpgs that I don't like. I prefer the softer base of the raw and apply smart sharpening to the key areas. This can significantly boost the 3d of an image. Being able to also selectively applying colour/tone enhancements to parts of the image is better from the raw.
