I have written a separate article about using a Cheetahstand Chop Stick with a Westcott Zeppelin. You can read that article here.
I conducted my first commercial session using only Godox lights and a Cheetahstand Rice Bowl 36″ modified to accept and use my DIY focusing parabolic rod. Since Godox has not yet released the AD600 remote head I used the AD360 on the rod due to its light weight. I am very pleased with the light quality, characteristic and my results. This will be my go to focusing modifier for on location sessions.
Rear glass was backlit by an AD600BM, no modifier, bare bulb. Key light was lit with a AD360 shot through a CheetahStand 36″ Rice Bowl modified to use a focusing rod, camera left about 10 feet away from the talent. No diffusion panels. Light was in a maximum focused position very close to the apex of the modifier. (pushed into the Rice Bowl) Light was pointed to the left of the talent bouncing the light off of the left side of the RB to illuminate the musician. This produces both a specular and soft light unique to a focused light which is different than a softbox. Pentax 645Z using a 45-85mm lens. Triggers were the X1C with a FT-16 trigger on the hotshoe of the X1C. Client is the Principal harp player for the Dallas Opera and the Santa Fe Opera.
The Cheetahstand rice bowl 36″ and I imagine his larger sizes with a focusing rod make controlling light spill much easier. This was taken WITHOUT his grid. The ability to carom light off the sides of the RB allow one to point the modifier AWAY from the talent thereby allowing one to direct the light away, but illuminating the bounced light toward the subject. Think of it like playing billiards when you do a bank shot off of the sides. Very effective because you can move the light inward toward the apex which is not possible without a focusing rod. More versatile than just a grid with different light qualities.
