Photoshop does allow you to do non-destructive editing using Adjustment Layers
rather than burning changes into the original pixels, but not, alas, on high-bit
files.
Admittedly, the blending computations necessary to implement adjustment layers on
16-bit channels might be quite intense for today's CPUs, but hopefully sometime in
our lifetimes we'll have the best of both worlds.

I had heard about 48 bit vs 24 bit editing, but never had a good reason to try it. Now I do, and I'll do some side-by-side comparisons to satisfy myself.
As I said above, Bruce has a way of clearly explaining gobblygook - Thanks!

This states the photoshop capability precisely. While Adjustement Layers are not available in 48bit mode, the standards adjustments like Levels, Curves and Hue/Sat are available.
I also appreciate the tip to make more complex selections on an 8 bit version and copy to the high bit. I'm always darkening skies and lightening shadows.

I came across this article , after reading this I have become a little confused in what to think . Please read http://www.digitaloutput.net/back%20edit/apr03/feature2.html
Bruce is right on in this article about 16 bit color & tone correction. It's crucial, if you want the highest quality from your digital files, to do the main global & local corrections in 16 bit. What many people fail to realize is even if you get a "perfect 8 bit" from your scanner, if you do a local correction in 8 bit, that area can still suffer from the loss of data that degrades images.
And. . .Bruces tip about setting up an 8 bit copy to use for the normal Photoshop selection tools is great. Not only can you do Quick Mask, but you can do Color Range or create channels such as complex gradations to use as a basis of a 16 bit selection.
If you really want to work like a real pro, do as much work in 16 bit as you can before dropping into 8 bit.
On one hand I can agree with "the better the resolution the longer you have better results"-opinion on the other hand it doesn't solve the basic problem: oposing to other medias, we are still working in a destructive way in most of the design programms. We have good "resolutions" in programms like illustrator, freehand and photoshop, but the longer you work on a file the more it's corrupted. If you ever worked on a harddisk-recording, or even the more object oriented way of QXP, you probably would prefer a nondestructive way of working and it would ease the work of editing and optimizing files for any purpose.

Right on

48 bit success
With the new Photoshop CS understanding the strength of 48 bit is even more important. This is a good explanation.
