I have been playing around with a couple of GentWire USB2 Canon triggers, CHDK and two ELPH 110 HS cameras (one converted by MaxMax for NIR images). My goal was to get them to take a picture at the same time so that I can use the images for stereographic measurements. However, the timing of the cameras is all over the place. Sometimes one first then the other, sometimes one doesn't take a picture, sometimes the response is fast, sometimes slow, etc...
I have tried connecting both trigger wires to the same RC Out (9) as well as separate RC Outs (9 and 11), but the results are the same. I'm telling Mission Planner to "Trigger Camera Now" from the flight data screen while the machine is on the bench.
Does anyone know where the issue lies and is it possible to get them to take a picture at the same time? A voltmeter is the only tool I have at the moment. I'm guessing that the issue is in either the CHDK environment on the camera, or in the camera itself. I've tried using the KAP script to force the parameters of the camera to be the same so it's 'searching' for the right settings before taking the picture. I just want a dumb, take picture now response, from the camera.
I don't have two of another kind of camera to try different responses with, but I know my Sony a5100 with a Farsight Mono cable has a much more consistent trigger response. The gentwire cable doesn't work without CHDK installed, does someone know of an alternative to use? I have a couple of artificial finger triggers that I haven't tried, but I would be surprised if they have better performance (although I could be wrong).
Any help would be appreciated, thanks!
