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

Dave, most grain removal programs wont work with such a star saturated image
because the sampling area is not clear of stars.  Use SGBNR to clean it up.

Als
Take Care,

 you can TRY the smart blur in Photoshop.

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


Hi All,

I finally had a chance to process some film shots from this year's Texas
Star Party and I wanted to share them and hopefully get some tips on
processing dark nebula to remove noise.  One image in particular (Pipe
Nebula - high res version) has some dark green pixels spread throughout the
dark regions that I assume are some kind of film grain artifacts???  Anyone
know what causes this and how to best process it out?

See: http://www.zianet.com/dave.dockery/NewImages.htm

Comments and suggestions are always welcomed.

Thanks much,
Dave
