Hello everyone! I REALLY need help with this tethering problem. I've also never tethered before. In Adobe Lightroom Classic live view I was trying to take a portrait shot. I'm shooting with a Canon 77D on a MacBook.
As you can see my live view is cropping the actual photo (1st attachment, smaller photo on the left is after the photo was taken). When I flip the live view orientation (second photo), it's no longer cropped. But that's means I'd have to flip my laptop on its side for the whole tethering session?? I can't even find this problem on Google and support has to call me back today because they couldn't figure it out (with screen share). Any help is highly appreciated, thank you!!
