RE: [APML] TSP wide field images and film grain question

["Dave Dockery" <dave.dockery@zianet.com>]

Thanks, Dick.  I appreciate the feedback and the suggestions.  I've tried
Neat image before it seemed to do a pretty good job.  I'll look at it again.

I also took Carlos's suggestion to try SCNR and found a webpage that
translated Juan's article to English so I'm giving that a try, as well.
Some of the text didn't exactly translate very well though.  Here's an
example: "Who it possess certain experience in the processing of images
surely will have, does already while, this question patrolling him the head:
well, but ?which is the price to pay? Of course that there is a
rice."  --LOL--  Needless to say it's taking me a little bit to work my way
through but it looks very promising.

Dave
