Tips for using the Nikon Intelligent Flash System
During the usual synchronization time, the shutter is completely opened and releases the entire image field. The image is evenly illuminated. This synchronization time is a maximum of 1/200 s, too long for some fast-moving motifs.
In the case of the FP short-time synchronization (high-speed synchronization), however, the flash delivers its light in the form of countless stroboscope flashes during the entire shutter sequence, ie exactly as long as the exposure gap takes to run over the entire image field. And that can be up to 1/8000 s. However, the high-speed synchronization has a sensitive hook because it reduces the guide number of the flash and makes sense only at short distances. FP can be used in P, S, A and M exposure modes.
