Keep the topic alive! I this camera is actually still years ahead of most cameras! For the price of $500 on eBay you can have a camera near the quality of an FS7 or a RED!
From what I have read on this post it seems having 3 customer picture wizard profiles makes it appropriate to switch as needed. I have found that moving the Hue to -6 also improves the tone of the image and so I set all 3 Custom Profiles to the same settings (-10 Sharpness, -3 Saturation, -5 Contrast, -6 Hue) except for the RGB sliders. So in bright contrasty light, I may use Custom 1 with the settings of R: .88 , G: .86 , B: .87 to bring down the gain on the sensor (to my basic understanding) and in Higher Dynamic Range Situations, May go to Custom 2 with the boosted settings of R: 1.88, G: 1.86, B:1.87 and Finally I have a Custom 3 profile with R: 1.44 , G: 1.43, B: 1.44. This is a bit more contrasty but still with a wide DR. All of these Settings also are running on 16-235 and Black Level at +15.
The results are pretty amazing just from playing around. Makes me want to find all the NX1s out there and hoard them!
