Drop shadow

The drop shadow is often used for elements of a graphical user interface such as windows or menus, and for simple text.

In general, a drop shadow is a copy in black or gray of the object, drawn in a slightly different position.

In photo editing or photography post-production, a drop shadow may be added right beneath a model or product in the image.

To add a drop shadow, retouchers use graphic editing tools like Adobe Photoshop.

In some operating systems like macOS, drop shadow is used to differentiate between active and inactive windows.
