TPB #44 – High Speed LED Flashes

Posted by:

This week’s video is about very high speed flashes and whether LED based flashes are practical at these speeds. The dominant flash in this space is the air-gap flash with it’s half microsecond flash duration it is about 100 times faster than a typical speedlite flash from Canon or Nikon.
