Shawn,(posted 8802 days ago)I wouldn't use a soft source as a main if I were after a "spotlight" [fresnel] main-light-look. Given your equipment at hand, I would use a bare head strobe as a main, with the umbrella as fill. Put you main close [because it has a low output], and move your fill away from the model to get the correct ratio. Set it up with a pretty broad ratio, such as 4:1, and you should be off to the races! I'd also look at what you're getting with the fill at a fairly hard angle to the model, like 90* or so.
The crossed shadow problem is corrected by increasing the ratio between your main and fill light[s]. FWIW, Sante D. shoots with huge HMI fresnel, with no fill. But his beam pattern is probably in the neighborhood of 10~15 feet, with no intensity variation throughout the beam. He also uses a KR12 to give it that sunset look [at least for the Victoria's Secret stuff of old]. We lil people have to improvise to get a similar look, and I think this should do it, but obviously on a much smaller scale.
Should a bought a Blad with a 'roid back! Hahahaha, just kidding. Good luck.
