Originally posted by stevebrot The high pass sharpening sounds interesting, but I don't have PS and generally limit my USM sharpening on scanned images due to artifact amplification.

Does anyone want to contribute a new thread on the subject for the PP forum?

Steve,
I will look into creating a thread. I once posted a tutorial and some Photoshop actions for masking and sharpening, but I think they got buried and the links to the actions are probably dead by now anyway. The good news for Lightroom users, is that these techniques(masking etc.) are now built in. It's my understanding that Bruce Frasier actually helped Adobe implement these before he passed away.
I would exercise caution using the Luminous Landscape's directions to anyone that intends to print at different sizes. 10 pixels and "hardlight" creates some big high contrast halos, which will only get bigger with larger print sizes and smaller(i.e. less effective) with smaller print sizes. I actually find it strange that they don't mention this and tell the reader to apply 10 pixels of highpass without any explanation of what those values do or how they'll effect the file. An 8x10 print with that setting from a 4000 SPI scan will have a different effect than the same size print from a 2000SPI scan. Same applies to Digital captures of varying resolutions and output sizes.
I don't want to sidetrack this thread anymore, but I'll see what I can come up with for a new thread. I use both Photoshop and Lightroom so I can probably touch on both software and also how you can use them together, particularly with scans.
