Use the Camera Shutter Release with Turntables

1. When to Use the Shutter Release Port

Use the shutter release port when you want the turntable to trigger your camera using a physical shutter release cable—typically when:

• You are using the turntable with third-party capture software.
• Your camera is not being triggered over USB in your current workflow.

If you are using Visere Captura with a supported camera, Visere Captura typically triggers the camera over USB tethering instead of using the shutter release port.

2. What You Need

• A Pictomic Silver or Platinum series turntable with a shutter release port
• A camera that supports an external shutter release/remote trigger
• A 2.5mm stereo shutter release cable
• (Optional) A 2.5mm-to-3.5mm adapter if your camera uses 3.5mm

3. Cable & Adapter Notes

The shutter release cable used with Pictomic turntables is a standard 2.5mm stereo cable.

• If your camera uses a 3.5mm input, use a 2.5mm stereo male to 3.5mm stereo female adapter (commonly available online).
• If your camera uses a proprietary remote connector, contact your camera manufacturer for a compatible cable/adapter that maps the camera’s focus, shutter, and ground signals to a standard stereo trigger.

4. How the Triggering Sequence Works

The trigger signals are controlled through an optically-isolated coupler. In general, the sequence is:

1. The focus signal is sent first (focus line closes to common/ground).
2. A few milliseconds later, the shutter signal is sent (shutter line closes to common/ground).
3. If focus remains grounded and the camera is ready, the camera should fire.
   
   

Model notes:

• Platinum series: Focus is signaled first, then shutter shortly after.
• Silver series: Focus may be grounded as soon as the cable is inserted, then shutter is grounded shortly after.

5. Step-by-Step Setup in Turntable Controller

1. Connect the shutter release cable:
   • Turntable shutter release port → shutter release cable → camera remote/shutter input
2. Open Turntable Controller and click Advanced settings.
3. Enable the option to trigger the camera via shutter release before the turntable turns.
4. To verify the setup, click button Trigger ... under Camera - Shutter Release to manually test camera triggeri

6. Troubleshooting

A) Camera doesn’t fire

• Switch to Manual Focus (MF): If the camera is in autofocus, it may not complete focus before the shutter signal arrives. To test, switch the lens (or camera body) from AF to MF.
• Confirm the camera is ready: If the camera is busy (buffering, writing to card), it may delay trigger processing.

B) Missed shots / inconsistent triggering

• Test with a short cable first: Avoid extension cables while troubleshooting. For setup verification, use a shutter release cable of 6 feet or less.

C) Issues when USB is also connected

• Some cameras may behave differently when USB tethering is connected at the same time as shutter release. Test shutter release without USB first.
• If it works without USB, reconnect USB and try different connection orders (USB first vs. shutter first) with the camera powered on.

D) A practical note about timing

• Although the turntable provides physical focus/shutter signals, the camera ultimately decides when it can execute the capture. If the camera is busy, triggers can be delayed or processed together once the camera is available.
