Friends at Microsoft Live Labs reported a unique search feature that allow you to look for faces.
- Portrait results return head and shoulders images, or what we often call mug shots. For example: ‘Adrian Grenier filter:portrait’
- Face results are closer shots with the face the most predominant element of the image. For example: ‘Aishwarya Rai filter:face’
- Black and white results are pretty self explanatory and works on any search type, not just people. Example: ‘night skyline filter:bw’
- You can even combine some of the filters: ‘George Washington Carver filter:face filter:bw’
