All flashes were set to manual output. With black surfaces – tuxedo & piano – being so predominant in the final composition of the portraits, TTL flash would’ve just made it more difficult. It had to be manually controlled flash. This is where the new PocketWizards made the shoot so much easier. I could control the power of each flash from the on-camera speedlight (via the on-camera FlexTT5). All without worrying about line-of-sight problems.
