Fake HSS mode via remote camera release

Uwe
edited June 2014 in V6 Suggestions
Would be nice if the V6 could support syncing at higher than xsync with cameras that are supported for remote shutter release. The Ojecoco H550 is capable of doing that. A user selectable delay for the flash after sending the shutter signal would be good to have. It should include the option for a negative delay - send out the flash signal BEFORE sending the shutter signal. Optional enabling of RF60 HSS sympathy mode would be great.

  • It would be incredibly useful to have some kind of hypersync functionality. 

    This feature alone would convince me to buy into the system.  It's almost mandatory when shooting outdoor action photos with studio lights.
  • It would be incredibly useful to have some kind of hypersync functionality. 

    There already is "some kind" of HyperSync functionality available.

    It is based on optical triggering. With a flash that allows manually engaging HSS, you can even achieve HSS (thus avoiding the gradation of HyperSync).

    What the V6 cannot do is to make the camera believe it is dealing with an HSS-capable flash, so there is no way around using an HSS-capable flash and optical triggering of a nearby V6, or using an HSS-enabling trigger in addition to the V6.

    Yes, I am aware on the HSS work arounds - and the limitations of the V6. That is why I was suggesting a sledge hammer aproach. You will also need a FP or HSS capable camera to begin with. What I suggested will work with any that can be remote released with V6 no matter if it can do HSS or not. It is not only useful for fakung HSS, but for other effects: normally you can only sync first or second curtain. You will have a leading or following motion trail. Some shots may be better with a leading AND following motion trail. I have not seen options for flashing in the middle ...

    Uwe, I didn't initially respond to your post because I wasn't sure what you were after and thought someone else could reply.

    If you are thinking about using a remote control to trigger both flash and camera at the same time, slightly delaying the flash so that the flash fires a bit in advance of the camera (which has a pretty long shutter lag), you can do that with V6s today.

    The V6 supports remote releasing the shutter of a camera -- you just need the right cable for your camera -- and a delay function. By not using the "relay" mode, but using the same channel for both camera shutter release V6 receiver and flash firing V6 receiver, plus appropriate use of the delay feature you can achieve any timing you need. It may be a bit tricky because the shutter lag of the camera may not always be constant but by putting as much as possible into manual mode (AF & metering), you may get consistent results.

    As for something between first- and second-curtain sync: Again, you can achieve that with a V6 today (and without resorting to remote releasing the camera). Just dial in a delay that corresponds to roughly half of your shutter speed and you should get motion trails before and after the subject. I did not experiment with this a lot, but during beta testing I produced a shot like you are thinking of in a first attempt to achieve second-curtain sync, using the delay timer.
  • Thanks, ClassA. Wasn't sure if delay would do the trick - it is not clear if a flash signal is needed for that or not. I assume if shooting above sync speed on a camera that is not FP capable (like my D3200), than the V6 would not know I just took a picture - and won't fire. Even if the camera is FP capable, it will only send a signal if a "compatible" trigger or flash is detected. The V6 is not, so my thinking was to have to use remote camera release so the V6 knows I am planning on taking a picture.

    The V6 can delay any kind of trigger, e.g., a radio trigger from another V6, an optical trigger impulse, a trigger from the sync port.

    So you could delay both the V6 that will trigger your flashes and the V6 that will release the shutter of your camera (with both being triggered by a third V6). However, you won't need to delay the V6 that releases the shutter of your camera because the latter has a lot of shutter lag anyhow. You'll need quite a bit of delay for the flash firing V6 to achieve not too much of a "negative delay" for the flashes.

    That depends on the camera.

    Many Nikon DSLRs (your D3200 may be one of them), still generate a trigger signal on the hot-shoe even if the shutter speed is set beyond the sync speed.

    If this is the case, you might be able to go up to 1/2000s or so, without needing "negative delay" (i.e., some sort of pre-sync). Only beyond a certain shutter speed, you'll definitely need a non-standard triggering signal.

    Uwe said: Even if the camera is FP capable, it will only send a signal if a "compatible" trigger or flash is detected.

    Again, that depends on the camera.

    Some camera models (e.g., from Nikon) generate trigger signals regardless of whether or not a compatible device is detected.

  • Thanks Class A !

    All of what I wanted is already built in. It is just not advertised as such. I am unwilling to play trigger roulette - even at the low price for a V6 considerding the included flexibility and features. For me it is still an investment, and not out of allowance for toys.
