I love shooting with available light although at times it seems more like available darkness.
I feel that a moment should be documented as is. That the amount of light at the time is as big a part of the story as the people or place.
The advancements in camera technology combined with fast lenses allows me to shoot in almost total darkness.
Although, I very rarely use my strobe (I used it last week for the first time in ten years), I have no problem piggy backing off of someone else’s illumination.
I am always taking advantage of tv cameramen’s light and occasionally like at this thrift show fashion show I will raise my f/stop and use a slow shutter speed to synch with a still shooter’s strobe.
