I apologize in advance if this is in the wrong place but without knowing technical terms I figured this was a good place to start.
At my local mall there was a photographer shooting Easter pictures for the kids. He had what appeared to be an antenna controlling the two soft boxes he was using for lighting. Also, he would take the pictures and you would walk about 50ft away to where he had the station setup where you pick the shots you like and pay for the prints.
My questions are what is the wireless device called that wirelessly controlled the flash and what did he use to send the pictures so quickly and wirelessly?
All I know is that he was shooting Nikon and I saw a little square white box that had the Apple logo on it and all the stuff at the pay station was Apple as well.
Is this something I can get for Canon?
