I guess I'm guilty of contributing to the technical gibberish. It seems one
doesn't get quite as much for what ones pays for in some ways than
before. The ability to change the downsize sharpening in Smugmug galleries
has been removed!---harummph, bah humbug, grrrrrr.
Smugmug doesn't touch the original image as far as sharpening, and does still
use the Lanczos algorithm with a default amount of 0.20 as before--confirmed by
Smugmug. I usually just upload a very large jpeg as the downsized images for
display were fine and the downsizing sharpening was adjustable anyway.
As Moose has explained in detail ( A Moose Monday article?), all downsized
images require some sharpening. Assuming the other parameter defaults are
unchanged the radius would be 1, threshold 0.05 with a sigma of 1.0. (Sigma in
this context is the relative weight of pixels as a f(distance from the
convolution kernal)
All these were adjustable for each image if one wanted before! Portraits were
best with tad lighter touch and some macros a bit more aggressive. People spend
much time, dosh and effort on their gear and images and how it is finally
displayed should be the photog's choice not some durn default. It does work
fine for most images most of the time, but that is besides the point for a
service like that, IMO. They could have just let it be and those that did not
want to fuss had the same default.
Victim of the default, Mike
