if you push USM hard Photoshop(200,150,0) or my prefernce
Nikon Capture(100,100,0)
is that 'legal' under basic editing ?

As long as the adjustment is applied to the whole image (no selection tool), it's legal under basic.

... but will likely be voted down if pushed to far.

With that large of a radius, however, it becomes another way to adjust the overall contrast of the image -- there are usually better ways to accomplish this (Levels, Curves to name two).

With one caveat: any photo is subject to disqualification if it is found to violate the "spirit of the rules," even if the result is achieved by "legal" methods. There is no way to know for sure ahead of time how your photo will be received, although it is suggested you contact one or more SC members first for an informal opinion.

If you put the image in your Workshop folder, it will not be seen by anyone browsing your Portfolio, but you can send us a direct link to the image and we can see it.

Basically, if it looks like a photograph it should be OK. If it looks like something created on the computer ("digital art") it could potentially be rejected.

I have personally pushed this line myself, although mostly long ago; you can see an example in this gallery at pBase based on this entry:

Filters: The use of filters (or non-Photoshop equivalent) is strictly limited. Any filter or stand-alone utility designed and used to preserve the integrity of the image and/or reduce the effects of noise, scratches, etc, are permitted. These include but are not limited to the Sharpen, Unsharp Mask, and Dust & Scratches filters, and standalone image cleanup utilities such as NeatImage. However, no effects filters may be applied to your image, with the exception of Noise and Gaussian Blur, which are allowed. Any filter permitted by this rule must be applied uniformly to the entire image. Selective application of any filter is prohibited.


(Emphasis added).

The "designed and used" phrase is key here, in my opinion. If your purpose is to create an effect, then in my opinion it will run afoul of this rule. We don't really have any precedent one way or the other on this though, so this is not an official ruling.

In any case, it probably wouldn't be well-received by the voters.

thankyou all

i will pull my sharpening back --
though if you notice USM in Nikon Capture (and PS to lesser extent)
makes a nice textured surface ...
but of course it is not in the spirit -
it does look like a art effect
