HyperSync/HSS Tab
87
• Shooting outdoors where the sky is a major factor in the top part of the image
• Using aperture priority in conditions that cause the shutter speed to go above X-sync
• In any situation where the full frame must be used and cropping is not an option
"Reduced Clipping" is selected on the ControlTL receiver, as shown in the section Configuring HyperSync.
Highest Energy
Highest Energy uses precision timing to get as much flash energy into the image as possible above X-sync. This will
reduce gradation, but can result in black bars or clipping in the frame. For many photographic situations this can
yield acceptable or useful results as clipping can be cropped out of the image. Highest Energy benefits
photographers:
• Needing as much action stopping flash power in the image as possible (remember that for HyperSync, longer
flash durations are better)
• Gathering images where gradation is not acceptable
• In any situation where cropping is an option
"Highest Energy" is selected on the ControlTL receiver, as shown in the section Configuring HyperSync.
P2 HyperSync Flash Duration
This setting controls the automatic timings used by a receiving FlexTT5's P2/Flash port. A setting of 1-3 (FAST) will
work best with a flash that has a short duration, like most hot shoe flashes. A 4-7 (MEDIUM) setting would be useful
for a medium duration flash, such as an AlienBees B400 or an Elinchrom 300RX, and an 8-10 (SLOW) setting
would fit best for a Profoto Acute series, or higher powered Elinchrom or AlienBees flash. Some experimentation
may be necessary to find the best setting for your camera and flash combination.
Note that the flash duration of most flashes change as power levels are raised or lowered. While fully automated
HyperSync remotes such as the PowerMC2, PowerST4 or AC9 can account for this, the P2 port cannot. This means
that the setting in use above will most likely be optimal only for a particular power setting on the remote flash, and
may need to be changed for a different power level. We recommend testing at the flash's full power to begin
experimenting with your equipment.
