I would like to know something more about the sharpening method that is just to the right of Fill Light in the Batch Filter. There is much discussion of Unsharp Mask, Smart Sharpening, and now Tone Targeted Sharpening in the help files and online but I have never seen an explicit discussion (or even any explicit mention) of the "plain old sharpen" function. What method is being used? What advantages or disadvantages does it have compared to USM? That kind of discussion is what I'm looking for.
Jim,
I used to know the exact numbers to the answer, but right now I can say that the Sharpen control that you refer to is a regular application of the unsharp mask in steps. I just don't recall the strength or radius numbers.
You can use that control... no problems.
I use it for a standard kick to sharpen a document or a scan of something.
I could use it on images, but I have more fun with Tone Targeted Sharpening.
Just for fun, Jim try the regular Unsharp mask with a setting of Radius 6 and strength 50
