Adorama TV has been mixing up their youtube channel lately, and this week features the TTL acrobatics of Joe McNally. Joe walks you through a typical street portrait as he accentuates the natural ambient light with a single speedlight gelled red. The more useful tip Joe gives is how to control the spill of your large softlight with an "egg crate" or softbox grid. I'm still shocked he pulled this shot off using only the Nikon D800 pop up flash acting as commander.
