It makes a difference what type of image it is. Enlarging a jpg will
give worse results than enlarging a tif or raw, for example. Try
decomposing the img into LAB and sharpening only the L layer.
I have an old 7 mp image that I'm trying to increase to around 10MP. I've
read it's best to increase by 10%, then unsharpen, and repeat process until
you get to the desired result.
I unsharpened with radius at 5, threshold 15, and amount .5.
When I finished the process. I viewed the image at 100% and it was terrible.
Any recommendations regarding the process or the unsharpened mask settings?
