![]() With the unit as you pass 1/200 sec shutter speed think of the flash as a contunious light source. Most flashes, as you say, shorten the flash duration with lower power settings. better stopping power.Īpperently, with the Priolite the flash duration is 1/200 no matter what the power setting. What about the flash duration of the light? Or is that considered shutter speed?īy lowering the power of the flash that gives a shorter flash duration. the cameras shutter didn't matter, its all about the strobes stopping power. Some of Eggerton's photographs had an exposure time of less than 1/10,000 of a second We have Harold Edgerton the electrical engineer and photographer from MIT to thank for invention of stop-action, high-speed photography. Set your camera slower than that and the strobes "flash duration" decides the "shutter speed" ![]() The strobe decides the shutter speed /stopping power.Īs long as you have your camera set at a sufficient slow enough speed to accommodate the tubes flash duration. I don't have the exact # 's in front of me.and each brand of power pack and strobe tube are a little different (small "pocket" strobes have even faster flash durations ) So it will stop the action better/faster at 1/6 power than at full power. It doesn't matter what you set your cameras shutter at, as long as the shutter is open long enough for the flash to complete/sync the exposure.IE if your camera is set at 1/60 say with 2400 w/s studio strobes the flash duration is around 1/200th.
