No.. it´s not a background but a real sunset. This is the kind of picture that you get with a powerfull strob and Hypersync funcion.

1. If you're using an Einstein E640, I gather you're also using a PowerMC2 receiver, otherwise you wouldn't be able to use PW's ControlTL logic.

2. Under ControlTL logic 1/3200 is not a speed that uses HyperSynch (a proprietary, trademarked feature of ControlTL). What you used was standard HSS/FP, as per Canon designation.

3. HyperSynch, under ControlTL logic, extends the maximum sync speed of the camera you're using it with, before HSS/FP kicks in. It is only active between the camera's max X-sync speed up to 1/640 (maximum, depending on camera).

4. It pays to fully understand what we're working with. It is also convenient to not lead people into confusion in public forums like this one by propagating misconceptions.

5. Be sure to cut out the "princess" concept by 11, 13 years old or she will bring it into adulthood making it very difficult for other people to interact on a positive emotional level with her. We Latins sometimes fail to avoid that educational trap.

6. Cute photo.

From the Pocket Wizard site:

  • HyperSync™:  HyperSync allows photographers to achieve faster X-sync speeds, all the way up to 1/8000 second*, with full power flash.  Now you can cut the ambient light and use wide-open apertures, outdoors in bright sunlight.  That extra speed can also freeze action, whether shooting models or athletes in motion. (*camera and flash model dependent).
  • HyperSync Automation: With ControTL Firmware updates to the MiniTT1 and FlexTT5 for Canon (6.0) and Nikon (3.0), adjusting HyperSync has now been automated.  HyperSync can now be adjusted in two seperate places - – on the transmitter and on the receiving ControlTL radio. The transmitting or on-camera MiniTT1 or FlexTT5 automatically adjusts HyperSync to compensate for changes made to shutter speed. Photographers can further refine HyperSync via the PocketWizard Utility. Please visit wiki.pocketwizard.com/HyperSync to learn more about configuring HyperSync with a PowerMC2.

As you see i do not lead people into confusion in public forums like this one by propagating misconceptions.

Agora relativo ao ponto 5 não percebi o que disseste

It is not enough to read the marketing material. Manuals must also to be read together with other amplifying material if we want to make good use of our gear.

In that text 1/8000 should be understood as a (valid) marketing gimmick. HyperSync, as concept, is the ability to push the max X-sync speed by means of fiddling with the time allowances of the signal. In this sense, it only works up to 1/640. Although it also true that it helps standard HSS/FP by optimizing times and output power it must be understood that the system is resorting to standard HSS/FP when working above 1/8000

From the MiniTT1/FlexTT Canon Owner's Manual:

O ponto 5 refere-se ao cuidado que temos que ter, enquanto educadores, para que o conceito de "princesa", salutar na infância e tão presente na sua foto, não transborde para a adolescência e, consequentemente, para a idade adulta.

Como alguém que tem que lidar diariamente com algumas (felizmente, poucas) mulheres adultas que ainda acham que são "princesas" e mundo lhes deve serem o centro da atenção, posso garantir-lhe que pode ser um problema nas relações laborais, problema esse que, em última análise, se torna prejudicial para as próprias.

Maior aprofundamento sobre esta ideia, só com em pessoa, com câmara numa mão e uma imperial na outra

Using the Tail

Thetailmethod uses the long tail of light generated after the peak is finished in a standard flash. This long tail is seen as continuous light for a shutter speed faster than X-Sync. Optimizing for the tail can often work for the fastest shutter speeds all the way up to 1/8000. This method delivers much less light to the camera's sensor than using the peak, but depending on your studio flash in use it can be substantially more than what is delivered by a Speedlight in HSS mode.

To use this method of HyperSync, you need to disable HSS in your ControlTL transmitter. See the Sync Timing Tab section in the PocketWizard Utility for information on setting "High Speed Sync (HSS/FP) Disable Mode." If you do not check this box for your transmitter, then you will not be able to trigger your remote studio flash at shutter speeds faster than "High Speed Sync (HSS/FP) Begins At:."

You optimize for the tail by adjusting the HyperSync slider to the left (more negative). This moves the peak of light such that it is completed before the first shutter starts to open. Then the flash will only be generating the long tail of light while the shutters are open. Depending on your flash's duration, it may be difficult to optimize for the shutter speeds closest to X-Sync as those require the longest flash duration.

This method is only effective with studio flash. Speedlites do not generate enough light during the tail to be more effective than using HSS would be.

Obrigado pela informação

PS - Pode ser que um dia venha-mos a estar com a câmara numa mão e uma imperial na outra
