UW Technics offers TTL Boards with HSS Support
Pavel Kolpakov of UW Technics offers an explanation of how High-Speed Sync (HSS) works and details the TTL housing boards that have been developed by UW Technics. He mentions that HSS may be useful for shooting near the surface, under bright sunlight, creative photography with different depth of field, and fast-moving objects. It may also be helpful with cameras that offer relatively slow sync speeds.
