Sel to Group (Creates a layer group that has the layer mask from the active selection and we are prompted to write a group name.)
Sel to Mask (Creates a layer mask from the active selection or if layer mask is present it replaces it with the active selection.)
Contract (Contract the layer mask by a specified amount in pixels (1-100px) and blurs it if specified.)
Expand (Expands the layer mask by a specified amount in pixels (1-100px) and blurs it if specified.)
Red (Selects only the red channel from the “MultiMatte” render element.)
Green (Selects only the green channel from the “MultiMatte” render element.)
Blue (Selects only the blue channel from the “MultiMatte” render element.)
Alpha (Selects only the whites from the Alpha render element, only if it is saved as a file that doesn’t support transparency by default for example .tif file.)
Bounding Guides (Creates bounding guides around the image or if the selection is present it creates the bounding guides around that selection.)
Crop by Guides (Crops the image based on the four bounding guides that represent the rectangle for the cropping. It is important to have only and exactly four guides for the tool to work.)
3×3 grid (Or the rule of thirds as used in Photography, creates the 3×3 grid from guides.)
Golden Ratio Grid (Or sometimes called a Phi grid is also used in Photography and it creates the 3×3 grid from guides in a golden proportion.)
Clear Guides (Deletes all guides.)
Show/Hide Guides (Works as a toggle and it hides or shows the guides.)
Add Noise (Adds the noise layer that has the blending mode set to “Overlay” and it is useful for adding a subtle texture if the material looks too plastic or it can help solve the color banding issue.)
HighPass (Adds the layer that has the blending mode set to Overlay and uses the HighPass fitler. It can be used to increase the sharpness of the selected layer.)
Snapshot (Merges all visible layers into a single layer and adds it to the top of the layer stack.)
Camera Raw Layer (Works similar as the Snapshot tool but with a difference that it creates the smart object layer and names it “CAMERA_RAW”.)
Clean PSD (Makes the Photoshop file a lot cleaner. It deletes all empty layers, capitalizes layer group names, deletes color test layers and adds numbers to the duplicates of the group names. Clean PSD can be adjusted to our preference inside the Settings tab.)
Export Selected Layer(s) (Exports the selected layer(s) as separate files.)
Save Image (Saves the image to the specified file format.)
