This video demonstrates wireless tethered photography / shooting with the low cost wireless device called PUB2 (Portable USB Box 2), which emulates a USB cable. The physical wireless cord is eliminated, to rid of the annoyance and the risk of tripping over the cord, which may result in injury to user and equipment. Photos can now be reviewed within seconds to being snapped. It's ideal for photo studios and for photography classes. Works with Canon, Nikon, and other DSLR cameras that support tethered USB shooting.
