I just can't get my head around lighting with flash. I can't understand how you can light creatively with light you can't see. So-called "modelling lights" are a poor approximation, IMHO. Shoot-and-chimp the same. No real feedback. A three-light strobe setup seems to be about as many as you can visualize. With continuous light, with three we're just getting started.
It ought to be true, but after a while you get a sixth sense for how it is going to look. Modern strobe units are extremely bright. They fire at intensity controllable AND REPRODUCIBLE SHOT TO SHOT better than 1/10th of a stop over a 6+ stop range just by twiddling a dial. You can read each light separately with a flash meter, which soon helps educate you what each light is doing, and you just get to learn what each of your light shapers does. The flash meter is your friend :-) but after a while you stop even needing that as anything more than a double check.
The killer feature though is that the light is very bright and fires SO quickly. With a leaf shutter lens on my 'blad and a Hensel portable battery flash kit, I can literally carry enough light in one hand that I can stand in a desert and overpower the noon day sun by four stops for 200 shots, or freeze action with flash durations sub 1/1000th, and make sure I can always shoot at f/8 or f/11 for optimum sharpness of the lens if I so desire. Try doing that with a continuous light. You'd need fixtures the size of a truck, and another truck to carry the generator to power it, and another truck to carry the petrol to fuel it :-)
And the cost would be astronomical compared with the price of a decent strobe setup. There simply isn't a continuous light technology that delivers light that bright from fixtures that small, cheap, robust and cool.
In principle, what you see is what you get is a very powerful way to work. But you don't actually get what you see with your eyes on camera even for motion- you get what the lighting looks like once it has been through the camera's gamma curve, colour response and so on. I need to chimp at the monitor to fine tune my light with continuous lighting too because it doesn't always register the same as it looks to my eye. Admittedly I have a lot more practice with strobes, but when you know what you are doing, lighting with strobes is pure pleasure.
