I, sincerely, I do not play xplane black and white or too green or blue saturation etc, the effect photo absolutely not interested if I go and go lightroom picture screen. I just want more contrast and better light distribution on the floor with a bit of saturation. € 20 just to increase 3 effect: saturation, color, contrast is, I think commercial use only. sorry for my bad english absolutely no need to have a plug-in with 20 parameters because you adjusted one time, after it's over. you do not change .. compare maxxfx and BLU-FX Color saturation and contrast only If BLU-FX is exactly the same on the 3 parameters, I think it is reflected! € 20 or free? I'm curious to have someone who can test the 2 plugin to compare the shadows and light effects..
