It's a real tough question. My rule of thumb is not to do anything to one part of an image that I don't do to all parts. The exception is in cloning out flaws like dust spots. -- Joe ________________________________ From: "jcarman6@q.com" <jcarman6@q.com> To: Utah Astronomy <utah-astronomy@mailman.xmission.com> Sent: Tuesday, January 22, 2013 10:34 AM Subject: [Utah-astronomy] Moon-Jupiter photo op Back in the old astrophotography days " bracketing" meant taking the same picture at different exposure times.  This was using actual film and you didn't waste photo ops - you covered your bases.  Jared's picture is a composite.  Don Parker takes/used to take incredible pictures of Jupiter and other planets.  Heard him speak and for every hour he spent with the camera, he spent about 12 hours at the computer doing what Jared did in order to get the most detailed, personally satisfying image.  Makes you wonder if what you see in the photo is real - at all.  I have often wondered if astrophotographers have eliminated some key detail to enhance something else .    _______________________________________________ Utah-Astronomy mailing list http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Send messages to the list to Utah-Astronomy@mailman.xmission.com The Utah-Astronomy mailing list is not affiliated with any astronomy club.
