Shutter speed and flash syncing

My last post on the Pixel Knight TR-332 TTL wireless flash triggers here had no photos of my own, just some vids on flash triggers and how the syncing worked (or didn’t work) on various cameras. This is more of that technobabble. Although unlike my vids, this actually provides some great insights on how this all works.  Paul Duncan does an excellent job of visually explaining how SLR shutters (focal plane shutters) sync in relation to small flashes like speedlites/speedlights.  It’s nearly 10 minutes, but if you’re interested in the nuts and bolts of how/why flashes work with your DSLR the way they do, this is a must-watch.
