Photograph the side of TK's head in the "TK Needs Zombrex" mission for 500 PP each time. Repeat this as many times as desired.

On Day 2, do the "Here Comes The Groom" mission. Get the Psychopath's attention away from you by leaving the building and returning approximately 30 seconds to 1 minute later. When you return, he should have the bride in a chokehold and will not release her until you get close. You can repeatedly photograph this for 5,000 PP each time.
