We've all had this problem: All we need for our little lights setup is a reflector, but there is nobody to hold the damn thing. And reflector arms are terrible. I hate mine, I never use it. It's large and doesn't stay where it's supposed to stay and it's heavy and a pain in the... well, you get the picture.
I pondered about why I could not attach a reflector to a ballhead and just move it about the way I move it the way I can move a camera? Why does it have to be so fiddly? I purchased a cheap light stand clamp from Ebay but that only allowed me to attach the reflector vertically on the light stand, and it was so heavy, it almost brought the hole thing down. MORE SAND BAGS! Like I'm not already carrying around enough!
Last night, I dismantled the light stand clamp. I removed the part that attaches to the light stand, and I found it was pretty easy to do. My clamp had who screw holes. 'Fantastic!', I thought, 'I'll just mount a tripod plate to it!' Not so fast. The pre-drilled holes were to small. It took me about an hour to widen one so that my old Joby fast plate could be installed on it. So far, so good. Now, let's attach my triangular reflector:
Oops. This won't do. It just hangs there like a wet sack. No good. The whole idea of a ballhead attachment is that I would be able to use the reflector as flag, up high, or underneath the subject aka clam shell light. How could I possibly reinforce the reflector itself, so that it would be stiff enough to be put upright, yet still foldable to store away in my bag??
You guessed it: a simple metal ruler, or a flat spatula, or whatever else you can get your hands on clamped underneath the reflector will support it enough to stand up or down or wherever you need it to be. Then you just remove the ruler, fold up your tripod back to its super small size, collapse the reflector and you have the perfect light modifier for on the go. This is only a small reflector, but that's all I really need for portraits anyway.
