You're saying with a strobe and a tight grid you cant create the exact type of spot in the original example??? Im surprised its that difficult, I see simple examples on youtube on how to grid a light and the beams look fine (though rather large).
Okay, here's my experiment. Be aware that projector fixtures and attachments do exist for your purpose. However, in the interest of science, I am using components that every self-respecting studio should have laying around.
First are the results:
First image has a bit of fill to anchor the floating face. Here is the actual spotlight as projected onto foamcore at the face position:
Next is the complete assembly:
From right to left is the strobe, the gel holder (empty), the snoot, the diffuser sheet (hidden), the aperture plate, and the Leitz 85mm Elmaron projector lens. By defocussing the lens, I can change the spotlight edge from hard to soft. After doing the above setup, I noticed the snoot and filter holder could be removed, making it simpler and more light-efficient:
I didn't bother to fix the increased light leakage. The spotlight has 34cm diameter from 4m away and, being an image of the diffuser at the aperture, can be adjusted to your desires: triangular outline, radial graduation, a signature, a Kodachrome slide of your friends throwing up during that high-school graduation party in 1978!
I suspect the strobe in my setup can be replaced by a Speedlight, but it will need full power. I don't see any way around the projector method, other than a high-quality parabolic reflector and frosted bulb (Maglite is a distant approximation).
