A luminaire was used to smoothly adjust the lamp's brightness. A luminaire was also needed to create smoke billowing in the lamp's bulb. The bulb was cut with a glass cutter. - - - This all relates to the first photo of the "TRIO." In this photo, I really snagged a freebie. I didn't expect the filament to burst after plugging it in with the bulb removed. And the smoke would look like a skull with tentacles. I used pulsed light for illumination. The background is black, either fabric or paper.
