VERY IMPORTANT for avoid any confusion due to weak precision of noises+colors of PNG image type:
-after completed rendering, should choose "EXR" image type with uncompressed, and with FP32 for insane color depth (this competes perfect true color at in the real life - much higher than 32-bit color depth) to save the rendered image;
- Free lastest "GIMP" - choose to click one of buttons before download and open any EXR file.

----- Great tips and Excellent and Happy rendering!
