when i make a mask and then use the brush tool it normally erases. then if i want the item to come back i use the erase tool on the mask and the item comes back. then i installed the newest version for PS and it now does the opposite, the erase tool erases the mask. but then a few days later its back to the old way where erase draws. is there some kind setting the is doing this?
You'll get much more consistent results by not using the Eraser tool at all and just using the Brush tool at all times. Paint with black in your mask layer to hide the image, paint with white to reveal it. Hit D to set your colors to default black and white, then X to toggle between them as you paint. Quick, efficient way of working.
It is easier to destroy than to create.
More fun, too.
