A pet peeve of mine is excess worry about being "non-destructive".
The word is misused. What you're doing (assuming you have any Photoshop capability at all and you're trying to make the image better, not worse) is constructive.
You should understand that the previews you see in Photoshop of your multi-layer image (unless you take extreme measures in configuration which I doubt many people know about) are all done in 8 bits/channel, so it's doubtful you're seeing what you're doing at a high quality level anyway.
If you really want to maintain all your layers and minimize the impact of sharpening, you can stamp the visible layers into a new layer of pixels above all the others (Control Alt Shift E) then sharpen it. If you have to work on the document you can just do it again afterward - it's not like it takes a long time to do.
But honestly it's not even evil to just re-develop an image from a raw file and do all the edits again. I find that I can often do a better job overall on a photo after doing that - and it avails you of the most recent advancements in Camera Raw.
I'm sorry if this message seems harsh, and please know that I'm not directing any criticism to anyone here, I just have a very strong personal opinion that all this "non-destructive" editing hype is just so much BS.

thanks for this advice. I've been sharpening normally in the background
layer, which is almost correct, if the other layers don't contribute by
extreme changes. Or after flattening, of course.
Concerning 'non-destructive': in my opinion you're right. An improvement
of image appearance isn't destructive.
A pity, that the Renaissance painters didn't know how to paint non-
destructive. If they had known, then Botticelli might have tried to improve
this really ugly left arm of Venus:

all I did was ask a simple question, and I got the hatfields and mccoys...
Any how I think I have it figured out....
1. I make a duplicate layer
2. choose my edit function and max it ...make a duplicate layer for each edit adjustment
3. all I have to do is adjust the opacity on all dupicate layers when I am happy with what I see
4. flatten the layers
and I think this is a non distructive way of doing it....correct me if I am wrong....the thing I like about adjusting in layers I can go basck and tweak as needed...My newbie way of thinkin
on a pc what is the key stroke for duplicate layer
Gernot, my understanding is that many of those ancient canvasses have totally different paintings underneath - owing to the scarcity of canvas to paint on. Thus the masters destructively used layers... I have a whole crate of these monkey wrenches today, and I'm not afraid to use 'em.
To R (station_two), I think I have earned the right to air my opinions occasionally. I believe you have too, though I fully understand your wanting to be conservative.
Capt, just another thing to keep in mind: No operation is truly destructive unless you delete your original files, right?
There are a countless number of ways to sharpen and image and a countless number of opnions on sharpenig. I sharpen in two placess a little upfront just to have a image a little sharper to work with then the images straight from my camera. I sharpen again for output and I like adding a sharpening layer to the top of the layer stack and blend the sharpening effect into the layer below. Using a blending mode of luminosity along with using blend if gray will protect colors, shadows and highlights. Makeing that layer a smart object will make filters use on it smart filters which can have a filter mask like an edge mask to sharpen edges and protect. Any filter you use like USM, Smart Sharpen, Highpass can be re-adjusted. You can additionally add a layer mask to the sharpening layer and play with its opacity and fill to adjust the sharpening effect and way you want to. Here is a link to an action I posted years ago as an example. You may want to look at it and come up with an action the fits in with your work-flow http://www.mouseprints.net/old/dpr/CS3_Smart_Sharpen_Filter_Adjustment_Layer.atn
