Hello there folks,
I wonder if any of you might contribute your opinions and tastes RE Photoshop's Unsharp Mask...
What I'm looking for here are some all-purpose numbers for all 3 settings...your "average" settings let's say, give or take...
Every image is different obviously, but I can't help but think there's a ballpark of USM figures here...
Would welcome any information, and I thank you in advance...

Hello Jack- For resampled images prepped for say BPN at 1024 wide and 800 high and sharp to begin with, my numbers are invariably around Amount = 75-100%, Radius = 0.3 or 0.4, Threshold = 0. However, I use Smart sharpen more these days and set to Remove Lens blur, Amount = 75-100%, radius = 0.3-0.4. For large images prepped for printing, the sharpening is more heavy-handed than this.

Jack,
I agree with John's post. Also see:

and the raw processing threads in workflow (we will start a new one this weekend), e.g.:

I'll also add, that depending on the image, unsharp mask levels will need to be different for different parts of the image.
