Thanks, no it attaches to the car in the shot. 3 metre aluminium tubing (in 2 sections) 1.5" od with a 10 gauge wall, two manfrotto 241 pump cups, superclamps and a 155RC head to attach the 50D.
Those last two shots I was really happy with, I was trying to get the contoured look so we tried a few shots with the Speedlite flashes (430EXII & 580EXII) on either side and triggered with the ST-E2 on the camera.
The location for those was on a business park, in some ways it's perfect for these shots as the some of the office buildings have this parking space underneath with the corrugated ceiling & strip lighting. Unfortunately security were a bit fidgety (especially as we'd turned up in these cars) but let us stay for a couple of hours.
The static shots were taken between 11pm-12:30am lol.
What I've found, as a limitation of the ST-E2 (and any IR transmitter for that matter) is that for backlit shots there's no LoS. So I've sold the ST-E2 and will use the command functions on the 580EXII for some stuff and will also buy some RF triggers so I don't need to worry about LoS. It'll give me more flexibility
