>>SNIP>>>As for the strip light not working for people, I don't quite get that. I don't have one, I have not fabricated one, but I don't see why you can't feather it pretty successfully. You'll get falloff, but you just put your big photographer pants on and work with it. Reflect it back, or make a picture that works with a pretty strong ratio. If it's good for wine bottles, why isn't it good for kids? Kids, as you may have noticed, are roughly the shape of a wine bottle..
Please let me take a polite approach to this with a little experiment. I've seen how you're lighting your still lifes, which are like wine bottles, but with vases and flowers. Yet still, inanimate objects, and very narrow in width, and pretty short compared to even an 18-24 month old toddler. So...let's "make" a strip light for you. Set up your lightstand and speedlight 12 inches from an open door that leads from one room to another. Tape 36 inches of typing paper over the open door, which is cracked open precisely 8 inches. Then, call your older daughter into the next room, and shoot some pictures of her, using the light that comes from your home-brewed strip light.
The issues? The kid will move, more so than a wine bottle. The kid is five times wider than the bottle and 2.5 times taller, and maybe 50 times larger in volume. The "sweet spot" of the light will be about four inches wide and 24 inches tall, with STEEP fall-off at the top and bottom of the beam on "most" Chinese made strip boxes when a speedlight is used inside, and not a 360 degree, circular flash tube from a studio monolight or flash head.
It's like herding wild cats, using a strip box on a real-life, live-action, 3-D,slobbering, toddling, wandering, amused, moving kid, AND the best part with speedlights? You are
shooting totally blind, due to lack of modeling lights. The thing with strip lights is they were really designed for studio flash, but they look cool. However, there's kind of a difference in the way speedlights light up some modifiers, versus the way round flashtubes with 360 degree output, around a "doughnut" shaped flash tube. There is also only ONE distance from flash to baffle to front diffusion cover. A strip light is a very rigid device, with options of a grid or louvres, but only a little bit of mods are possible. Not much "range" of effects on a strip light.
A MUCH, much,much,much better solition is a 11.5 inch parabolic reflector with a 50 to 65 degree beam spread; a metal honeycomb grid in 10,15,20, to even 35 degree spread, then a snap-on mylar diffuser, or two stacked or even three stacked mylar diffusers (or Tuf-Spun, whatever), and then a set of 2-way barn doors. Now that, that actually "WORKS', AND WORKS "RIGHT". It is a strip of light that YOU can control to the
nth degree in terms of specularity/diffusion, spread, and width. And, with real studio flash units, you can actually SEE where the damned thing is aimed! Woo-hooo!
NO offense, but hey...I could go to the dump tonight with my semi-automartic .22 and maybe hit a rat and killone or two if I fired 500 rounds in the dark...if I used a .410 shotgun with a flashlight taped under the forestock. I could probably kill 1,2,or 3 of the little buggers each SHOT. Right tool, used with enough light to SEE WTF is happening...
