A comprehensive article has been published on controlling Nikon Speedlights with precision using PocketWizard FlexTT5, MiniTT1, AC3 ZoneController, and a Sekonic L-758DR lightmeter with the RT-32CTL Radio Transmitter Module.
Author Dinil Abeygunawardane has posted a fascinating tutorial on the Visible Range Blog. It’s absolutely worth your time to read. The article details how to set up the above list of gear with Nikon Speedlights and dial in specific light values for different units remotely.
The radio trigger for the Sekonic works with the firmware update for the PocketWizards (at time of writing, still in beta) to make the whole process more convenient. As Dinil writes,”No more running up and down, lowering light stands or opening up soft boxes.” Photos of the lightmeter’s LCD and screenshots of PocketWizard Utility abound.
