Saturday 16th August saw the 4th running of MaxAdventures Go Natural Multisport. I was working for Aus Triathlete Mag and also to produce some marketing shots for the race organiser. My plan was to have shots look more commercial than normal event photography. Here is the final result.

I wanted to light the subject with the Sun as the main light and 2 x 580EX as balance. Here is the lighting plan in minute to-scale detail (NOT!!)

The sun is the main light as front 3/4 to the camera right, so to balance that out I used 1 x 580 as front 3/4 to camera left. For fill I used a second 580 at 180deg to the sun. To have full control over the flashes I wanted to use ETTL from the ST-E2. I have not used this unit nearly enough, and in this application, it was just perfect. I needed to be able to change camera settings without having to run around changing flash power. Bike riders are hardly going to wait for me!!!

Notice that the IR modules on the front of the 580s are pointed to where I was standing and the heads are pointed to the subject. This is to the IR receivers can “see” the ST-E2. The IR signal is line of sight so if they can’t “see” each other, then it just doesn’t work. The 580s are both set to SLAVE and one is A and the other is B. I have a ratio set on the flashes of A:B=2:1. With the ST-E2 I have full control over the flashes from the camera; Exposure, High speed sync, ratios etc…all from where I’m standing.

So what’s the down-side? These units MUST have line of site. If the flashes were in different locations, I might not be able to use this set-up. I have seen shots where flashes are hidden behind trees….not possible with the ST-E2s. However for this sort of thing….Brilliant!!!
