Many, many thanks for the replies - very helpful indeed - it’s great when it all starts to make sense.
@afre The post that got me thinking and really prompted my questions was this one: Sharpening Workflows - #2 by patdavid
@ggbutcher Thanks for the images - that’s the kind of difference I saw as well - subtle but when doing high resolution work I thought it might be worth doing twice. But I have a question for you - when you do your minimumUSMsharpen - what radius/amount/threshold do you use as a rule for thumb for the sharpen-post-scaling?
@garagecoder Thanks for the explanation of the unquantize function.
Thanks again - this is very informative.
Cheers,
Jules
