 Welcome back to another Dolby Photoshop tutorial and this one is going to show you how to create a black layer mask or a black mask. When you click on the mask button normally it creates a white mask just like I did here and you can paint with black and you can get rid of things. But I'm going to show you how to use a opposite mask so that you can go ahead and use a black mask and then paint to add instead. So the first step is you hold down the alt key or the option key if you're on a Mac and then you click on the mask button. This is the first step and then you can now paint with white and instead of removing this now adds into the image as you can see I'm doing here. You can feather the edges if you see fit. That said I'm going to delete this mask because a lot of times you create a white mask and then you go hey how do I turn this into a black one instead and all you got to do is hold down the command and the I key and that's it. If you don't have the command key on a Mac you can hold down the control key on a PC. That's all there's to it. Thanks for watching.
