Hell no, my kids are anything but cooperative. I hate shooting them sometimes because they don't listen and all I do is yell at them. Ahh well. lol Luckily enough my sis and bro in law where there. She took the shot, while he held my softbox on a boomstick about 3 feet from them.
Here's another one of my princess. She loves posing for the camera and I always get good shots from her. Although I kinda wish I woulda centered the softbox now, so it didnt create that shadow side on her.
You make a good point. When using the strobe in tbis type of application its really a fill light. And fill lights are most useful when they are on, or close to, the camera axis. Especially important when you are doing kids amd beauty shots.
