The Next Capture Naming tool offers a number of options for counters. With the default Camera Counter token, Capture One keeps track of the specific camera used during tethering. A four-digit counter is adopted, starting at zero the first time the camera is used tethered and thereafter increasing by one with each capture.
The Camera Counter cannot be reset and continues regardless of the session or catalog in use. Additional Capture Counters are available to allow full control, however, you can adopt both the Import Counter and the Capture Counter when working between a tethered camera and another one with a memory card. This allows consistent numbering in both of those.
When only the original file name is required from the camera, replace the tokens in the Format field with the Original Filename token instead.
