Focal black-and-white post-processing is in portrait photography an easy quick fix to guide the viewer’s eyes to the subject’s face, particularly to his or her eyes. In street portraits, it helps the subject’s face to stand out and to isolate the face from the sometimes cluttered background. Like a magical colour spotlight, focal black-and-white editing creates a beacon of focus and attention within a seemingly monochromatic world. It’s round shape is easily adjustable to any size and softness/sharpness. It's best to centre the focus in between the subject eyes (or slightly below) for portraits in full-face view, and onto the subject’s closer eye for portraits in three-quarter view.
Focal black-and-white post-processing works by having a street portrait appear as though it were taken in greyscale or black-and-white, with the subject’s face "colorized" as in the examples below (done with Picasa 3.9).
