The attached image can be used to calibrate gamma correction. You just need a program that can apply gamma correction, e.g., GIMP. Without any correction (gamma = 1.0) the image should produce a visible moiré pattern. With correct gamma applied, you should not see any pattern. Gamma = 1.8 works best for me. What is your gamma correction? Please reply for survey purposes. Than you, Alexei
