The Lite Tite from Arri is the perfect accessory for the job.
We are now official distributors of the LiteTite from Arri UK and below is my suggested rig for use with a Canon Speedlite on a Lovegrove Flash Bracket on an Arri 050KA lighting stand.
Click the jump to see how the flash head can be rigged inline with, and touching the umbrella shaft…
The LiteTite umbrella holder in use. Triggering umbrella flash with infra red has always problematical but now with radio triggering umbrellas are now a useful accessory on location with Speedlites. In this rig: Canon 580EX11, Pocket Wizard Flex TT5, Lovegrove Flash Bracket, Arri Lite Tite, Arri 050KA stand.
With the Canon pop up wide angle diffuser in place the umbrella is literally filled with light right to the brim all round. Be careful in windy conditions as this kind of rig becomes a kite.
You can get the Light Tite bracket directly from our shop here. If you have any questions please ask away below or ask me on Twitter.
