You may...

rotate your image in 90-degree increments (90, 180, or 270 degrees).
resize your image.
sharpen your image using any global, non-selective sharpening tool.
fully desaturate your image using your editing software's "desaturate," "convert to grayscale" or equivalent function. Customizable tools are not allowed.
use a tool to remove sensor dust, etc from your finished image.

Is there a limit (it used to be two, I think) to how many times we are allowed to "sharpen" our minimal editing image?

What does the "etc" mean after "sensor dust"? What are we allowed to remove from our minimal editing image?

I had originally interpreted it as a single pass of sharpen, but others have been doing multiple passes. I think it would have to be challenged to get a definitive answer, but the rules don't say how many passes.

I had thought that both the sharpening and resizing was a one-shot deal with each.

I know I always liked the Adamus sharpening on a double size image then resize to clean it up.

That doesn't seem to be a minimal type of procedure to me.

I believe you can sharpen as many times as you like.

I believe the etc. for dust removal might extend to other imaging artefacts - dead pixels perhaps. And, it would extend 'dust' to sand particles, hairs, spit (oh yes, I've tried to blow dust from my sensor before) etc

Correct on all accounts.

Specifically, on sharpening, there never WAS a restriction on how many passes could be made; THAT had to do with resizing, and you could only do it once, so originally Adamus sharpening was forbidden, but not now.

Thanks, folks!

FWIW, when SC cleaned the rules up we had consensus that neither resizing the image or any form of whole-image sharpening was really against the spirit of Minimal Editing. Obviously, we have to allow resizing, and we couldn't see any reason it shouldn't be done in steps if that's how you want to do it. The gains from doing it that way are, to be honest, imperceptible in nearly all cases. The sharpening was a different issue: clearly, since this is *minimal" editing, we can't allow localized sharpening; it has to be done to the whole image. But we were seeing a gray area creeping up regarding the idea of non-adjustable sharpening, because some of the newer stuff on phones, especially, only HAS adjustable sharpening. And it seems like if whatever sharpening one applies is done evenly to the entire image, that's pretty minimal right there...

Speaking for myself, on my "normal" entries I almost always sharpen with a mask, some areas receiving more, some less, and some even made LESS sharp, so it's minimal to ME anyway :-)

I hope this information is useful as the underlying rationale for the change...

I love history of the site posts. Thanks.

So... does USM work in Minimal... as long as it's image-wide?

Yup to USM.
