This Vid below shows a quick Photoshop run-through of how to use different brushes and the pattern stamp / rubber tool to create the effect of Displacement Portraits using Photoshop 7 and basic digital techniques.  It is intended to be similar to the work of Alberto Seveso- just without glitz and boom of the latest Photoshop (although I do love the new one as well).  I made this vid to support La*ra Is*ed on her powerful journey through her AS exam (names have been changed to protect the innocent)- Good luck to all sitting their exams.
