Taken from a local theatres production of jesus =Christ Superstar - this is Judas having a bit of conscience trouble.
I took a series using the lighting directors light and absolutely no flash.
To get the skin tones something like, I set the camera to manual with f4 - biggest I can get, 1600 ISO and 1/100 to 1/80th sec and waited for
relatively motionless actors.
I was able at the "dress" to go onto the stage and get close up and personal.
A touch of colour noise reduction in Photoshop and a few other tweaks with sharpening and not to shabby given circumstances.
