I think most of us have seen movies where someone in front of a computer screen, instructed by their superior to interpolate and sharpen a really fuzzy image, miraculously zooms in on facial features, or a car number plate, to reveal everything as clear and sharp as anything taken by a P&S camera from about 6ft away.
Hollywood fiction of course, but lots of fun.
I find Photokit Sharpener absolutely the reverse. On page 14 of the PDF manual there's an example of the difference between 'narrow edge' sharpen and 'wide edge' sharpen. Since I don't seem to be able to copy and paste from a PDF format, I'll describe it. There are two small crops from an image consisting of fine foliage and entangled branches. The right-most image is 'wide edge sharpen', the 'left-most image' is 'narrow edge sharpen'.
I can see no difference that matters at all. If there is a difference (engaging in extreme pixel-peeping), the 'wide edge' sharpen is very,very marginally better, in my view. Maybe there's an error. They've got the images reversed. Either way, it's a non issue for me and I wonder what all the fuss is about.
Mark seems to think that PK Sharpener is a breakthrough. I can't see it yet. What am I missing, Mark?
