As in digital we get instant feedback it makes for less stress wondering if we got the shot or not and certainly know what to do ahead of time to get the next one. As far as a color shift goes that comes out so fast in post processing its not funny. But one could play around with a few adjustments to so do in camera so what you first see popping up looks totally good. Here's my ten minutes time exposure off my website. http://rabinergroup.com/ImagePages/Laterellefallspage.html I shot this a few months after got my hasselblad which was 7/21/1979 when I shot it hand held 27 years later in 2006 on the way to NY with Elmo the dog it didn't come close to cutting it. Got to go back with my tripod which I just got a new head for. Now to get an L bracket. Oh I used an 81b color warming filter to protect the lens (which needed it with this shot) and absorb the hell out of any UV). I also used the now legendary Verichrome Pan film. Which is black and white straight line film. Which I ran in Beutlers.
