Re: [APML] Astronomical Image Enhancement Trial

Well, I guess I'll be the odd one out.  My impression is that the
processed image has a flat and harsher appearance than the
original.  Maybe I've seen too many images overprocessed in
the CCD groups and have come to appreciate the softer look
of a less aggressively processed film image.

(This would be easier to compare if you used a mouse-over)
