Deze revolutionaire nieuwe flitskop maakt gebruik van de IGBT-technologie voor het produceren van een zeer korte flitsduur, dat zelfs hele snelle acties kan bevriezen bijv. springen, dansen, martial arts, sport en zelfs barstende ballonnen.
Here are the flash duration test results, published in Advanced Photographer. They (and many other testers) use a spinning disk as the test method, and simply takes a series of photographs using a high performance camera without flash, these shots are taken at various shutter speeds and provide a benchmark, showing the action freezing potential at any tested shutter speed. The shots are then re-taken, this time using the flash unit under test, and the results can then be compared.It's a pretty good testing method, because shots taken at, say, a shutter speed of 1/10.000th second produce a very similar result as a flash with a t.1 time of 1/10,000th second.The problem though, is that although this is a very useful and meaningful test, it isn't scientific - a visual comparison needs to be made, and an estimate arrived at.
