It's only part of my workflow, right at the end.....
It goes....
All the copying and editing...then backup the fullsize edited TIFF.
Then before I close the shot down, I resize to 700px longest edge.
Then sharpen a few times (small amounts repeated, rather than one big go)
Then add a border and tag, and save.
So just before the end really, AFTER resizing.
I dont do any sharpening on the full size versions at all.
