How do you invert a layer mask?

Inverting a layer mask means making the pixels that are currently hidden by the mask visible. This is done by selecting the layer mask, clicking on the "Invert" button located in the Layer Mask palette, and then adjusting the settings as needed.

There are a few things to keep in mind when inverting a layer mask:

-The inverted layer mask will be placed over the current image, so make sure you have it positioned where you want it before inverting it.

-If there are any areas of your image that should remain masked (i.e., parts of your image that you don't want to show through), you'll need to fill those areas in with black before inverting the layer mask.

-Be careful not to accidentally delete any part of your image while inverting a layer mask; if this happens, you'll have to start from scratch and re-create your desired effect.

There are a few ways to create a new layer mask. One way is to use the "New Layer Mask" dialog box. To do this, open the Layers panel and click on the icon that looks like a white paper with a black cross in it (the letter M). This will open the New Layer Mask dialog box.

To create a layer mask using this method, first select the area of your image that you want to protect from being deleted or changed by future edits. Next, click on the icon that looks like three overlapping squares (the letter V). This will open the Vector Mask dialog box.

In this dialog box, you'll need to specify what areas of your image should be protected by your new layer mask. You can either enter specific pixel values or use ranges of values. For example, if you wanted to protect all of the pixels below 100% opacity, you would enter 100% into the "Start" field and 0% into the "End" field in the Vector Mask dialog box.

Once you've created your layer mask, it will appear in front of all other layers in your document and will be invisible unless you choose to show it using one of Photoshop's various tools (such as selecting Edit > Show All).
