I am shooting with a cooke 229mm lens on a 4x5 camera. I am wanting to shoot at f/4.5 to get the softest lens effect as possible. With my Bowens Gemini 500 Pro monolight set at the lowest setting, 15 watts/sec and with a one-stop reducer in the softbox, I can use only one light and must keep it around 8 feet away, otherwise the shot is overexposed. I am shooting ASA 100 at 1/125 sec. at f/4.5. I would like to be able to use fill lights, hair lights, etc. without that overexposing the film. I thought of using tungsten lighting, so I bought a 650 W Tungsten Fresnel, but with that I have to get 3 feet away at the tightest spot to shoot at the same shutter speed and aperture. I don't really want to go below 1/60th sec., and I don't want my models melting under lights so close to them. Also, the tightest spot covers less than 1 foot at that distance. With a 650 W flood, forget about getting enough light. I have done some reading on the internet already. Some suggest going up to a 2000 W Tungsten fresnel or larger, but that would mean I would have to get farther away, which would lead to loss of light intensity. Why the fresnel? I love the look of fresnel spotlights of the old Hollywood portraits of the 20s and 30s. Oh, and I can't afford HMI.
Thanks for reading my lengthy question,
