Measurement result for the ultra-fast pre-flash of the built-in flash unit of a Nikon Coolpix L830 camera.
In this example, visualization was configured to show the full horizontal and vertical grid.
Generated by an FDM-1T flash duration meter running a beta version of the upcoming new firmware 2.16 which, among other things, is going to significantly extend the unit’s working range to 1/120 000 sec ≤ t0.1 ≤ 1/5 sec.
Estimated release date of the new firmware will be mid/late May 2017.
