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.
"SHOW DOWN IN LITTLE TOKYO" starring Cary Tagawa was a movie that also incorporated what we call the "wet process." The wet process is used for major sized tattoos that actually circumference the whole body. In this process we print the tattoos and while the ink is still wet, we transfer the patterns on to the body. The principal tattoo make-up artists were Mr. Blau and Mike Hancock.
