I'm playing for the musical Evita and just got a call from the director asking if I would take some publicity shots of the cast for social media tonight. Apparently the photographer from the local news paper is coming too but it turns out he won't share his pix so this is very last minute. Gear is a Pentax K-3 with a 16-85 F3.5-5.6 lens. I don't have a flash but I think the stage light will be full on so probably not needed. I usually shoot in P or Tv but I've never shot photos that people count on before so I might chicken out and just put it green mode and take tons of shots. Thoughts?
