Hi,
I made the TIFFs and measured MTF with Imatest.
Left image: My default sharpening
Center: My defaults + 15% unsharp mask at r=3
Right: Coarse sharpening in LR where I used my defaults but increased radius to 3 in LR
Now, check MTF at 60 lp/mm:
Left image: 0.8
Center image: 0.95
Right image: 0.55
This was a very coarse demo, but I need some sleep ;-)
The problem with the left method is that it doesn't push the MTF for low frequencies where the eye is most sensitive. The righthand method does not really improve that much on fine detail, but it was just a coarse demo.
Note: This test image was made with a 100/2.8 Macro at optimum aperture, sharper than usual.
Best regards
Erik
Erik, could you provide more detail on the two points you made above?
Thanks, John
