We can now thank Nik for making up a totally bogus, unnecessary term (Raw Preshaprening), a good 6 years after the late, great Bruce Fraser came up with the concept of capture sharpening (sharpening in stages):
Sorry if this is another vendor you've issues with :-) :-) ...I was only looking at what they offer in the software.
I find the post conversion sharpening generally not so useful since I tend to have already used the sharpening found in whatever RAW converter I choose to use.
Sometimes in the past I've turned off most sharpening when processing a RAW image, doing some selective sharpening, then resizing to a large print size, before sharpening more for print. I'm not doing this very often, and didn't have an example to include in the review.
For my own personal use, it's the selective print sharpening that is useful - I include a mention of other features for completeness. As they say YMMV ;-)
