| p.1 #4 · Email esponse from Quantum about co pilot and PW Mini |
When I answered previously, I was awaiting delivery of the ControlTL stuff to try again... particularly with the claims for increased output with other lighting and that 'long duration' flashes are preferred to show the best results. It previously didn't work out last time I tried this, more specifically with Speedlights and on camera use and the stability of the PW system. This time I had specific objectives in mind, these objectives were:
a)Increase full output performance if possible by using Hypersync with Quantums and their FreeXwire system, particularly in combination with the CoPilot.
b)Add function to Speedlights, specifically increased output at full power on camera, if necessary by exceeding my maximum x-sync to obtain ambient reduction.
I didn't achieve either of those objectives and this was using 'Hypersync Only' with no FP/HSS.
What did work was that the Hypersync offset was transferred from the TT1 to the CoPilot so the CoPilot could use the retimed sync. Shooting beyond x-sync with the TT1 and CoPilot combination I could adjust power output between 1/1 and 1/2 and use those outputs. Those output values had no effect on image brightness, both 1/1 and 1/2 provided the same level of brightness but with less even frame coverage (more gradation) for 1/2 power.
Using an SB800 on a D3x in combination with a TT1, I obtained +1/3 more output at 1/250s and could step my shutter and aperture between 1/250s f11 - 1/800s f6.3 with no loss. Likewise, there was no gain.
On the bad side the CoPilot lost all TTL control and didn't sync at any time.
Since I can already step my shutter from 1/250s to 1/8000s by using just the CoPilot and 1/1 output the introduction of a TT1 offered no benefit.
Overall, it was a worthwhile experiment. If you want to use a Speedlight on camera, you can go beyond x-sync and access a wider aperture keeping ambient at the same ratio but for me and using Quantum equipment adding a TT1 into the mix added no benefit.
Let us know how you go on.
