EyedropperΒΆ
The eyedropper (pipette icon) allows you to sample from anywhere in the Blender window. The eyedropper can be used to select different kinds of data:
- Color
 - This is the most common usage.
 - Objects/Object-Data
 - This is used with object buttons such as parent, constraints or modifiers to select an object from the 3D View.
 - Camera Depth
 Number buttons effecting distance can also use the eye-dropper.
This is used to set the cameras depth of field so the depth chosen is in focus.
