Was not sure where to post this.
I was trying to shoot tethered using Lightroom for the first time yesterday. The Lightroom part I figured out OK. The problem was that every time I attach the USB cable from camera to computer the shutter button locks up and the camera reads busy in the viewfinder. Making it impossible to take a pic. Any help would be greatly appreciated. I have a Canon Rebel T2i.
Thanks
Karen
