First I was made paler than I usually am, with a slight green tint for the just-turned-into-a-zombie feel.
Veins were applied thickly, but would be faded a little bit later. I had some painted on my arms/hands as well. (Don't I look like such a charming zombie in this shot?)
Add contacts, and voila: instant zombie! And check out the blood covering my hand! This shot was taken in the middle of the day, during some of my down time. The contacts were really terrible for about the first twenty minutes, which was surprising as I had been putting them in and leaving them for increasing periods of time the whole week leading up to the shoot. Eventually I adjusted and was fine for the remainder of the day.
