I've started to notice that one thing a lot of photos I'm stylistically drawn to have in common these days is the use of continuous lighting with one or more HMI Fresnels, occasionally in conjunction with daylight. Given that this type of setup would set me back tens if not hundreds of thousands of dollars, it's not something that's particularly feasible to just pick up or even rent to play around with.
I'd like to start experimenting with this sort of lighting, but I'm not exactly certain what route to take. I see that profoto offers 2 fresnel modifiers, but they come in at $1500-2000 each, plus an additional $500 for barn doors which seems just a little ridiculous. Perhaps there's some way to jury rig another fresnel lens to work with a flash head that someone's familiar with?
I'm not certain something like a 650 watt Arri Tungsten is going to give me enough light to work with as even if I shot on a tripod at 1/60 I'm still losing ~6 stops of light vs. an equivalently powered strobe. I guess bumping ISO up to 800 or 1600 and losing 2-3 stops probably wouldn't be the end of the world.
Suggestions or any experiences working with something like the lower wattage Arri's for photography, particularly something like fashion or portraiture would be greatly appreciated.
