Kenai does her famous beg to jump up move that has earned her so many treats. A move she has been doing since she was a pup. Not one I taught her either.
The image here was made by using the Stroboscopic function of the 5XX series Speedlites. This is only one frame (release of the shutter) where the speedlite fires a selected burst of flashes. In multi mode you set the power of each burst, the number of bursts and the interval between the bursts. Hand held.
