Hi John very nice kitesurf action
Ken i used my daughters tripod and Sony HVL-F58AM for light mounted on the camera ( not optional but it worked ) distance to the lens was about 10-15 cm / 4-5 inches so way closer than what the flash is made for
and i also used the 10sec delay on the shutter to get rid of vibrations from pushing the trigger ( dont have a remote ).
shot in raw/jpeg mode and camera settings was ISO 400 F/25 1/60sec and i did it at night so natural light was poor to say the least
had enormous help of the focus coloring on the display.
