This photo was taken with the Nikon D70 and the ultra wide 12-24mm DX lens. It was a nice day to test the various user designed custom curves on the D70 to pick the one that I feel most acceptable as the default curve on the camera.
In the end, I chose the sReala curve because of it's overall balance across the tonal range in a picture under overcast sky. Different extreme lighting situation demands for different curve setting to compensate but sReala is the most balanced one that I see for general photo situation.
