• Set C-TX shutter sync to Hi-speed sync (HSS).
• Flash output of 1/1 may be needed for this technique.
• Take a test shot and check image for a shutter shadow. Adjust the timing between 0.0 and
2.0 until the optimum lighting is achieved.
• There may be a gradient in the image which will need correcting in post-processing.
