Even the best studio lights can struggle to capture sharp results on moving subjects. It’s got nothing to do with shutter speed and everything to do with flash duration.

Mini TT1 is a radio trigger from Pocket Wizard. It fires the flash even when the flash is off the camera (and attached to another pocket wizard)

Flash duration is a time measure taken from a flash between it reaching 50% of its peak value to the point when it has diminished to the same value.
A shorter flash duration freezes moving objects, a longer flash duration causes them to blur.

@pofrani
Nothing to do with recycling time, the flash from the flashgun lasts a tad longer than studio lights and therefore throws more light onto the subject for longer and allows for a sharper brighter image.

@danelovell I’ve done work for GGW. I’m almost 100% sure it is the theme song… However, I’m a HoeyHead, a Gavin follower if you will. I’ve liked all his videos thus far. I’m a pro photographer (meaning I get paid a few times a week to shoot models) and still I find his tutorials helpful and informative. That being said… I’ll still watch his videos… even thought that song is a bit creepy in this video. LOL. But otherwise good work as always Gav.

now what did you mean by duration? as in the reason you didn’t use studio flash is because of duration? did you mean recycling time?

Thanks for this awesome tip. I never do studio work, but I guess it will come in handy when I do branch into studio work.
