A problem has developed in my photoshop CS 6 64 bit on windows 7. I can't paint at full opacity in a layer mask. It is like an 75 % opacity brush. I have gone back to the default brushes soit is not the particular bursh. My brush settings are all at 100%, mask density is 100% , the blend mode is normal,-can't think of where else to look for the solution.The brush works just fine when I am not in a layer mask. I updated the graphic card driver and also the wacom intuos driver. It has to be somewhere in photoshop CS6 as when I go into my older version photoshop, cs5, the mask opacity works works at 100 % opacity Any ideas of what to do next.
