If your camera is supported and set up correctly but AI Photo Booth Pro cannot connect to it, or loses the connection after a while, there are a variety of reasons this can happen. The most likely causes are listed below.
- USB cable is damaged or low quality. Connect the camera using a high-quality USB cable, not an HDMI cable.
- The USB cable is too long.
- The USB cable is defective.
- The USB hub you are using is defective or cannot supply enough power.
- The camera power adapter is defective or not supplying enough power. Use a genuine Canon/Nikon power supply and retry.
- The power supply to the camera is interrupted.
- The camera is set to turn off after a specific duration.
- Windows turns off power to USB ports after a period of time. See Disable power management for USB devices for steps to fix this.
- The USB port on the computer or camera is damaged.
Things to Try
- Try a different, shorter USB cable, preferably the one that came with the camera.
- Plug the USB cable directly into the computer, not through a hub.
- Try a different USB port.
- Replace the camera power adapter.
- Close any other photography software such as Adobe Lightroom or Mac Photos.
- Put your camera on Manual Mode.
- Go to Settings, then Camera Settings, and change all the settings for both Photo and Video.
Canon
- Use a fully charged battery rather than a power supply. Some power supplies are known to cause issues.
- Delete the EOS Utility.
- Turn off Wi-Fi mode if available.
- Set the Mode Dial to Manual (M).
- Set Live View Shoot to Enabled.
- Set Live View shooting AF mode to Quick mode.
- Set live view shooting metering timer to 30 minutes.
Nikon
- Close Nikon Camera Control as well as any other apps that may be connecting to the camera.
- If using an older Nikon camera such as the Nikon D40 or earlier, make sure the camera USB Mode setting is set to PTP.
