Time value: shooting time (Tv camera value) [Papywizard Camera Tab]
Do I understand correctly that "Time value: shooting time (Tv camera value)" under the Camera Tab in Papywizard is referring to the amount of time the circuit for triggering the camera is completed?
My camera (Fuji S2) has no port for a remote trigger nor a IR sensor. I am concocting a servo-based solution based on a new product from gentled: it is the gentled autoFINGER. Primarily it is an intervalometer that will cause a servo to nod at intervals from 2 to 30 seconds. However, by completing a circuit between the negative pin from the battery and an otherwise unused pin, the device triggers the servo nod on-demand. This motion will be used to press the shutter on the camera.
My Startracker Multifunction Head (same as Orion/Merlin) finally arrived today ! Everything works perfectly out of the box ! However, my Tronisoft kit still hasn't arrived , so I am unable to run the head and camera trigger from Papywizard. However, to test the servo system, I set it up to cruise and shoot at six positions. Sure enough, it works and triggers the servo as desired. However, the time interval that the circuit is completed to trigger the camera is too long, resulting in the servo nodding three times So, I am hoping that this "Time value: shooting time (Tv camera value)" is what I am thinking it is so that I can get the servo to only nod once.
Also: It seems that the circuit that is closed is only between the tip and base ring of the plug. The middle ring seems to be connected to neither of the other two. Does that sound right? In another thread, I read that the base and center rings were connected, but that doesn't seem to be the case for me.
You can reduce the TV value, which is the time the shutter contact remains closed, so the servo is not triggered several times, but you also have to ensure that it is long enough so the entire shutter cycle can complete before moving to the next position.
If you need a better control over the pulse, I will add more parameters. Another guy seems to have troubles with its 400D, because the pulses are too fast when shooting in bracketing mode...
So, I'm open to ideas for these parameters. I think the Tv value is important, because it is the shutter cycle time. Then, we can define a ratio for the pusle (high vs low), or the delay of the high level, or the one of the low level, or both (one moves the other, so the Tv value is constant). I will do the timing datagram today, so it will be easier to discuss...
About the jack socket, it may be wired differently on your head. But this is not a problem: just use the contact they give in the doc (there is only one, in all cases).
