Boing !
So I was looking how the in camera flash can be used to control a remote flash, (which I do not have yet) but in the process discovered that my camera can repeat the flash for a number of times and decided to try it
The repeat function for the in camera flash can repeat the flash at a specific frequency for a number of times, number of repeats increases by using a reduced power
I tried shooting a bouncing ball, with a long exposure.
Best results are shown here
Flash set to repeat at 40hz, 25 times, 1/64 power. so that's about 1/2 second of flash
Had the plastic ball bounce at aprox 0.5m (minimum focus distance for the particular lens)
1 sec exposure
F11
ISO 1600
I wanted to have the ball contrast as much as possible versus the background, which is 7m away, and in the dark, but with 1/2 a sec flash it is still quite visible.
Not the best photo, but an interesting and fun experiment
I do not know how these feature will be used for anything else than playing
Thanks for looking
