There is a Beauty Dish on a strobe head camera left with a soft cover and grid. Its a speedotron product attached to a speedo head. The power pack was called the explorer. Its a reasonably priced portable power pack made by speedotron. The flash duration is around 1/750 sec which is good and worked for this shot.
I placed one head pointing back towards the camera lighting the building and one head with a grid on the car. The last head was aimed at the camera right side of the building. I drug the shutter to open up the ambient light. it was a great shoot. Love the 50’s.
P.S. I was just playing with the Speeo pack. I am looking for the best portable option for me and what I do. I do need portable power and am looking hard. This was a good product and may be the choice, I’m still looking.
