TB3 is not triggering camera to shoot?

If your camera is not triggering at all or not when it is supposed to, please look at the potential reason this could be happening below:

1. The camera cable is not plugged in.
2. Your cameras autofocus is turned on.
3. Your not allowing your camera enough time to process images. Try bumping up your interval time (this is explained in “How do I setup my first shot”).
4. Make sure you are not set up to take bracketed shots or in HDR mode (unless this is intentional).
5. Understand what your cameras shutter speed actually is. For long exposures, try timing it with a stop watch. You may be surprised to find that the actual time your shutter is open is different than what your camera is telling you by a significant amount.

If this problem continues to occur after you have gone through these potential reasons, please contact submit a request.
