Create Mask
One way to create a mask is with the built-in Create Mask tool.
Set the value of the mask with the "mask level" slider.
The masking effect of a mask is at each point determined by the masks value. A value of 0 totally masks any operation on the masked image.
For edit operations the mask is simply affected the same way, rotate also rotates the mask.
