SLR Cameras via USB connection

Supported via third-party application "Sparko Cam"

Digital SLR cameras made by Nikon or Canon can be used for calibration, connected with a USB cable.

For this purpose, the camera has to operate in the web-camera mode.

While some cameras have this mode in their firmware, most cameras do not , so a different third-party software can be used for this conversion:

Please note: Since there are so many types, brands, and models of cameras, as well as a lot of third-party software converters, we can’t test them all. As a result, we can not guarantee that your camera will work for the calibration process. Please perform some tests beforehand.
