I just finished several FoCal Aperture Sharpness tests with the D800E to try and find what camera settings impact QoF results. I used a 24-70mm lens set at 50mm and f/2.8.
The tests were as follows with Picture Control (PC) and White Balance (WB) as shown: - PC Neutral, WB 5200 - PC Standard, WB 5200 - PC Standard, WB 2800 - PC Neutral, WB 2800 - PC Neutral, WB 2800 with Circular Polarizer on
The only one that made a difference is with CP on. The Quality of Focus (QoF) went up by 6-7% with the CP installed.
This should make folks (like me) who almost never take their Nikon thin CP off feel better. It actually improved the quality of the image...well, it did here in my garage using a black and white target.
BTW, the actual target WB was about 2400 but FoCal only goes down to 2800.
