Q - What is the difference between a depth map and a focus map?

A - It is important to recognize the difference between a depth map and a focus map. They are not the same. A depth map contains information regarding the location of objects within the scene. A focus map contains information regarding the focal point of the camera. It is not recommended that you use a focus map as your depth map because this will confuse Depth Of Field Generator PRO since there are two depth map branches. Instead, it is recommended that your depth map is output from white to black and then the focus set within the filter using the Focal Depth slider. For instance, if you wish to have an object located in the distance in focus, you would not generate a black to white depth map despite the fact that white generally means objects will be in focus and black that objects will be defocused. Instead, you would generate a standard white to black depth map, and then set the focal depth controller (F-Depth) within the filter from 255 to 0. This will effectively change the focal point from the foreground to the background, as seen by clicking on the "View Focus" button.
