One of my favourite subjects for photography is the theatre. Obviously you don't normally get the chance to take pictures in the theatre so it's usually limited to school performances etc.
However in this case we were invited (after making a considerable contribution to the cause) for a show, in which a the artists, the theatre (Carré, Amsterdam) and every one else involved offered their services for free.
Making pictures, using the ambient light, with a camera from the hand, is quit a challenge, but the results can be rewarding. I've used my Canon 20D with the 24-70L 2.8, and the 75-300 IS lenses. The camera was set to 1600 or 3200 ASA depending on the light.
The Dutch members here may recognise some famous Dutch performers.
