Double click the Quick Mask icon on the tool bar to get a dialog box with options for mask color and mask opacity range. I think the default mask opacity is 50%.
To see the action painlessly, set the rectangular marquee to a feather radius of 100px or so (for a typical image—more or less if atypical), make a selection with it, then click on the QuickMask option. The central part of the selected area will be clear and it will get cloudy toward the edges of the selection and cloudier still beyond the edges.
If you have set the mask opacity to 100%, the outer part will be totally opaque rubylith (default color). In order to see through the rubylith mask to an extent with which you are happy, lower the mask opacity range. The option you set is the maximum, representing full 100% opacity in the image. The mask opacity then ranges from 0 to that maximum, representing the full image opacity range 0 to 100%.
Thanks, Yes, I knew how to set the color and opacity. You indicated I could set the graduation. I assume now you meant it changes as a result of opacity change.
