I agree that for web display, lo-res, your example is better to my eye and a 4x6 print would probably not exhibit appreciable difference to a discerning eye, definitely not for my target audience. But to perform this type manipulation to perhaps 1/3 of ~1000 shot session where similar iso is present would take time that I cannot provide, especially with 3-4 sessions per week. My target audience is High School athletes' parents and ..., who view on-screen and print few but like to see their sons performing. Therefore I exhibit many photos that I am not expecially proud of, but provide entertainment and memories for the parents. Plus you are much better educated in digital manipulation of images than I which makes me hunt and experiment too much :^) Thankyou for your efforts, I have learned something more and undoubtedly will find future application. ps: I have also found that much of the background noise may be masked w/o much subject degradation by increasing slightly the dark level. I am still amazed at how good darktable's output appears at >6400 iso with my D7100 and even better with my D3. -- (paka)Patrick Shanahan Plainfield, Indiana, USA @ptilopteri http://en.opensuse.org openSUSE Community Member facebook/ptilopteri http://wahoo.no-ip.org Photo Album: http://wahoo.no-ip.org/gallery2 Registered Linux User #207535 @ http://linuxcounter.net ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
