Gail's husband is into photography and uses a program called CAMRanger. Leo says that's a great app for syncing a camera to a computer or mobile device. Many cameras are using that tethering capability natively now as a result. But she's heard that CamRanger can fail, losing the images or requiring reinstallation of the software. Leo says it could be a bug, but he knows a lot of pros who use it and they haven't complained about a bug like that.
Leo says that for the studio, it's great. But when out on the road, suddenly CamRanger isn't all that practical. EyeFi cards may work.
