This might possibly open a can of worms, but anyway, here goes.
I've been playing with a print, about 8 x 12 inches, and scanned it
at a variety of resolutions. Mostly this was due to my scanner
misbehaving horribly, and swapping parts of the image around, and I
tried several scanning resolutions to find if that would get around
the misbehaving.
In the process, I found this.
When I scanned at 66 pixels/inch (25.98 px/cm) I got an image that was
(height = 20.01 cm / 520px / 7.87 in.)
(width = 29.56 cm / 768 px / 11.6 in.) as a pdd file
I presume the jpeg I converted it to is the same.
I adjusted colour and brightness, and did one simple sharpen. I did
not re-
size. The image has come out quite sharp with none of the over-sharp
artifacts one sometimes sees, including none of the white halo >> effect.
When I scanned at 168 px / inch then after adjusting colour,
brightness and contrast, resized and sharpened in that order (I
think) I just could not get it as sharp no matter what method I used,
and sharpening artifacts appeared quite quickly.
Are you getting the same result when you print? With my old version of
Photoshop on my old computer anything viewed at a resolution that did
not have an even divisor looked horrible, such as 1/3 or 2/3 views.
Amazingly that is much improved with a new computer with Elements. So
you may be reaching a conclusion based on your viewing apparatus. Did
you try printing and get the same results?
