Not to repeat myself, but I will. Sharpness is highly overrated.

That would depend on the size of the image file. An E-1 image has only 
5MP, whereas the typical camera of insanity today has something like 
30-50MP. There certainly is a point of diminishing returns as any form 
of pixel-level detail is completely gone by the time it is presented 
in final output format. 

What you do gain, however, with this tool is a sharpening effect that 
makes a lot of sense with our zillion-pixel cameras that are shot at 
higher ISOs. At base ISO all cameras are pretty much at best-possible, 
in terms of sharpness across the entire brightness spectrum. However, 
at higher ISOs, there is significant loss of detail in the shadows and 
in certain types of random patterns, such as foliage. They usually do 
an excellent job of maintaining edge detail in the shadows, but 
everything else turns to mush. I did a quick look at a canon file and 
it appears that this tool does demush the mush. The edges of the trees 
are no different, but the details (both perceived and real) within the 
trees are better. 

I am a firm believer in pixel-peeping. It's part of my process of 
maximizing the quality of the file. However, I don't let that get in 
the way of allowing a less than perfect picture make its way to final 
output. A good picture is a good picture regardless of pixel-level 
perfection. 

At this time, I'm having to keep SilkyPix around just to convert the 
occasional DMC-L1 image because of the pattern noise. I was hoping 
this update would address that, but it doesn't.
