I have a project that requires to dslrs to be mounted to walls and fired with tethering. I know that I can have both connected and just select the one that I want to use. The problem is that one camera will be tethering from 20 ft. away. I understand that info can have a hard time transferring at that distance with a cable. The camera is wifi capable (nikon d750). Is there a way to use the camera's wifi to tether directly into lightroom? Any other way to get this done?
