Been reading a LOT lately about continuous lighting. I've dabbled in off-camera flash using some cheap speed lights and I'm fairly comfortable using them. I'm now looking to re-create some hard light style portraits from 1930's, 40's etc and like the look of fresnel lights for achieving this. However I'm not clear on what size fresnel lights I would need to achieve decent exposure without cooking my model to a crisp. Would a 650 watt Arri fresnel be enough for key light, and 300 watt be enough fill / hair light ? Or do I need more grunt ?
I'm planning on shooting in a basic home studio in my double garage. I'll be using a 6x6 SLR camera and shooting wide open f4, 150mm focal length with 100 speed film.
