Most of the time, when the full size images have been treated this way, my reductions from zenfolio for web display look great. (some good examples here) I post process with SilkyPixwith all sharpening off. False color reduction does a great job of reducing chroma noise when converting to jpeg. After developing from Silkypix Pro, I batch in sharpening using Irfanview. I use Picasa as my viewer and some times do some luminosity adjustments and cropping there. For large sets of photojournalistic photos like partys, family occasions, etc. the results are very good.
If I were to reduce for e-mail I would reduce using Irfanviews resampling Lanczos filter and decide then whether to apply a little USM (100-150)or sharpening @ < 50.
Of course, if I'm working on very important payed forwork in Photoshop, I'll use USM most of the time to get the image ready for print.
Good thread topic Nate......!!
