Photography Reference - Take pictures of real abrasions, bruises and cuts FOR REFERENCE. If possible, take pictures during the healing process. Keep a file of actual facial features, beards, moustaches, noses, eyes and what ever else you can think of as well as wounds and burns etc. These can be invaluable.
"COPY CAT" starring Sigourney Weaver presented another challenge. Because Ms. Weaver had to look tortured, beat up and bruised, the challenge was to be able to makeup the wounds and not interfere with her performance by multi 'touch-ups.' Mr. Blau used the REEL Cover-Up/Effects Palette and REEL Body Art Inks. Because the inks were long lasting he had to do minimal touch up's and Ms. Weaver had time to herself to keep in character for the very difficult scenes she had to act.
