On this video, photographer Jay P. Morgan from the website the Slanted Lens takes a look at freezing action using stobes at night.
You might think that a storbe fires its light immediately – but it doesn’t – a strobe has what is known as a “flash duration” – the time it takes for the strobe to come to peak power and than to fall off. Morgan explains in a graph (see below) how it works and what are T.1 and T.5 when it comes to flash duration.

This isn’t the first time Morgan looks at freezing action – in the past we looked at is video on “Freezing Action With Speedlites“,
