I took the advice of a photoblog friend, Wasichseh, to try a freeware program for noise reduction.
Here is a comparison set. I have the 'before' photo first, and the filtered photo night scene second and full noise suppression third. I think it made a nice improvement especially in the first shot. I use adobe lightroom, and it has some noise reduction options, but this one seemed to work better. I used the 'night scene' settings. It might be possible to get even better results with tweaking it, but I honestly didn't know enough about the settings to make custom adjustments. Thought it might be interesting to see the comparisons.
BTW, I ended up returning my new lap top-- I was disappointed with the LED screen, it had a very pixelated look (if that is the right way to describe it), jagged edges-- not near the clarity of my 4 year old dell inspiron (which does have a bit of a brownish tint to it, LCD). The new one was a Toshiba satellite-"HD TruBrite LED-backlit TFT LCD widescreen displayNVIDIA GeForce 310M with NVIDIA Optimus, 4 ram,Intel Core i5-450M processor2.40GHz (2.53GHz with Turbo Boost Technology), 3MB L3 Cache4GB DDR3 system memory 'Gives you the power to handle most power-hungry applications and tons of multimedia work' 500GB SATA hard drive"- it has very good reviews. I set all the display setting and graphics card settings to the highest quality, but still wasn't clear and sharp. I also had a terrible time trying to get the excessive blue tint out of the display. I was going to attempt to calibrate it following advice of Revenant, when the touch mouse pad started to freeze up for no reason and require re-booting several times. That was the last straw for this machine. So, back on my old inspiron, and will probably get another dell when I have a chance. I was having difficulty running lightroom on my less than 1 ram memory, and 100 gb hard drive -it was freezing up a lot and suddenly shutting down. Most of my photos are on an external hard drive. I did learn another lesson-- don't move the photos to the external drive without going through lightroom. I lost all the lightroom editing steps. I still have the original photos, and the saved final edit, but I can't go back and tweak them and see what I had done from the original to get the final result. There might be a solution to this-- though I couldn't find it in the 2 books I have on using lightroom. Live and learn :)
I recently got Lightroom 3 and am very happy with it although it keeps duplicating files onto my original hard drive when I was trying to keep them on an external hard drive. Can't quite figure that out yet. I think it does a great job with noise. Your photos are fabulous and I love that red moon! Can see the difference and like it the most in the photo of the gals on the boat!
