Filming/shooting commercials…

This evening Zolex is shooting film. It’s material to make demonstration clips and commercials of their products. It’s a fume bench with built in fans to prevent inhaling dangerous gases from the chemicals they are working with on the bench. Customers are laboratories, pharmaceutical industries, universities, hospitals etc. We made smoke tests of several kinds and by lightening correctly (and using a black backdrop) we made the gases/smoke visible on film to demonstrate the deferens between a normal fume bench without the fan system (smoke going everywhere, and inhaled by the operator), and their bench with the extra fans system (and the smoke going where we want it, no inhalation of it).
