So right now I've got 1 flash, Youguno 565EX and a "10ft" cable for off camera purposes althought I only feel safe pulling about 3 ft on it. So I want to take some larger group family shoots this next week so I'll be using a 450D with flash and 50mm 1.8 lens for the shots with 6 or 7 people in them. Prob gonna take the shots on a golf course or desert in Tucson. I'm debating weather on camera will work in this situation or if I need a cheap transmitter to bring the flash closer to possible back light the group? I'm having a hard time finding examples on youtube to see examples on how to setup the shot. Thanks.
