When working on intricately composited, multi layered documents, I often find it useful to check each of the layer masks before finalizing the image. To do this, Option (Mac) / Alt (Win) -click on the mask thumbnail in the Layers panel to display it. With the mask visible, check to see if there are any unwanted awkward transitional areas that might not have been visible in the complex composite (a sharp edge from a selection or hard edge brush for example).

Command (Mac) / Control (Win) + “\” (backslash) targets the layer mask in the Layers panel. Command (Mac) / Control (Win) + 2 targets the layer.
Drag a layer mask or vector mask thumbnail in the Layers panel to move it from one layer to another.
Option -drag (Mac) | Alt -drag (Win) a layer or vector mask thumbnail in the Layers panel to create a copy of the mask.
Option + Shift -drag (Mac) | Alt + Shift -drag (Win) to create copy of a layer mask while simultaneously inverting the mask. (Note: this shortcut does not work with a vector mask – in order to invert a vector mask, select the path with the Direct Selection tool and click the “Subtract From Shapes Area” icon in the Options bar.)
To delete a mask, target it on the Properties panel and click the Trash icon at the bottom of the panel.
If you prefer to use the layers panel, target the mask and click the Trash icon, or drag the mask thumbnail to the Trash icon at the bottom of Layers panel. If you prefer to bypass the option dialog box, add Option (Mac) / Alt (Win) while clicking the trash icon will delete the mask without applying it.
Most of the time, I prefer to Control -click (Mac) | right -click (Win) on the layer mask and choose delete or apply the mask from the context sensitive menu.
To add a mask to a layer, click on the “Add Layer Mask” icon in the Layers panel. Click once to add a layer mask and click again to add a vector mask (or you can Command -click (Mac) | Control -click (Win) the mask icon to add a vector mask).
To add a layer mask that automatically hides the content of the layer (or the selection), as opposed to revealing it as it does by default, Option -click (Mac) | Alt -click (Win) the icon.
Use Command + I (Mac ) | Control + I (Win) to invert a layer mask, or click the Invert button on the Properties panel!
In this Episode of the Complete Picture Julieanne discusses how the addition of color as well as supporting imagery can help reinforce the mood and message of a composite image that a single photograph may fail to do on its own.
In this Quick Tip, Julieanne reveals a simple technique to paste content directly into a layer mask in Photoshop.
Option + (Mac) | Alt + (Win) -dragging a Smart Filter from one layer to another has different behavior based on where in the Layers panel you click and drag from. For example, Option + (Mac) | Alt + (Win) -dragging from the text “Smart Filters” will duplicate the Smart Filter including the layer mask:
While Option + (Mac) | Alt + (Win) -dragging the name of the Smart Filter duplicates without copying the mask.
If a section of a mask isn’t quite correct, try using the Dodge or Burn tool in the mask to subtly adjust the edge (by lightening or darkening the grayscale values within the transitional area). In this example, the original mask is too soft and as a result, we can see a green halo around the edge of the leaf.
Looking at the original mask, we can see that the edge of the mask needs to be reduced in width as well as shifted towards the edge of the leaf. Note: This is also known as “choking” the mask. Moving in the other direction would be “spreading” the mask.
Using the Burn tool on the mask’s edge, darkens the values in the transitional areas of the mask, narrowing the transitional area and moving the mask in towards the leaf. (I realize that the change is subtle in this illustration, but notice how the edge of the mask in the illustration below appears sharper than in the illustration above.)
As a result of choking the mask, the green halo is removed from around the edge of the leaf.
Layer masks in Photoshop are white by default, they are not transparent—even though they control the opacity/transparency of the contents of the layer.
If you Option + (Mac) | Alt + (Win) -click on the layer mask thumbnail in the layers panel, you can view the contents of the mask. You will not see the checkerboard which, in Photoshop, represents transparency. Instead you will see white, black, or any shade of gray.
Where it might seem confusing is that the result of the mask is to show or hide the contents of the layer – in essence, hiding/revealing varying levels of transparency. But this is achieved by painting with shades of gray in the mask, not transparency.
To customize Photoshop’s keyboard shortcuts to add a layer mask, select Edit > Keyboard Shortcuts. Set the “Shortcuts For” to Application Menus and toggle the disclosure triangle for the Layer menu. Scroll down to layer Mask and add your own shortcuts by clicking in the blank area to the right of the command. Click Accept and then OK. Assigning shortcuts is a quick way to add a layer mask while ignoring/respecting the current selection.
If you make a selection in your image and then add a layer mask by clicking the add layer mask icon at the bottom of the Layers panel, the layer mask will be created based on the selection. If you need Photoshop to ignore the selection when making the mask, Option + (Mac) | Alt + (Win) -click the add layer mask icon at the bottom of the Layers panel or, choose Layer > Layer Mask > Reveal All.

Of course this isn’t a complete list, so feel free to search the blog for more in-depth tutorials, training, techniques and shortcuts for working with Adobe Photoshop and Lightroom.
To create a mask on a layer based on the transparency of another layer, in the Layers panel, select the layer that you want the mask to be added to. Then, drag the layer that you want to become the contents for the mask to the Add Mask Icon at the bottom of the Layers panel. Important: don’t click and release the mouse on the layer that you want to become the contents of the mask – clicking will select the layer, you need to drag that layer instead.
Option (Mac) / Alt (Win) + Shift -drag to create copy of a layer mask while simultaneously inverting the mask.
I suppose that some of you are thinking, “Julieanne, you’ve posted this shortcut before”, but here’s the tip: if the mask’s Density or Feather slider has been altered from their defaults (of 100% and 0.0 px) using the Properties panel, this shortcut will not work.
With that said, you can still use the shortcut to duplicate the layer mask (Option (Mac) / Alt (Win) -drag the layer mask thumbnail in the Layers panel). Then, to invert the mask, click the Invert button in the Properties panel (or use the shortcut Command (Mac) | Control (Win) + I to invert).
Many thanks to Meredith for identifying the cause of the disabled shortcut!
