Yes. What you're envisioning is something that's actually used by some TTL-capable radio triggers to allow faster shutter speeds with manual flashes and studio strobes: it's called tail-sync (aka "HyperSync", "Supersync", etc.). The problem, as Loong has pointed out, is that the light/power output of the flash pulse is not even and constant during the ...


In principle, your rationale is correct. However, there is no usable period during which an ordinary single flash is emitting at constant power. The power of a typical on-camera flash quickly increases from zero to its maximum value in about 0.1 ms (i.e. 1/10 000th s). Then it exponentially decreases with a half-life of roughly 1 ms; i.e., it decreases to ...


I think a key complication with doing it this way round is going to be getting the flash to be able to synchronise with the shutter at that level of precision. Eg, what happens if there is a long sync cord, or a radio trigger? They may cause different amounts of lag (I realise that the lag with a longer sync cable will be negligible and may not make a ...
