Peter Girolami’s Journey From Third-Generation Filmmaker to CEO of SourceMaker

For Peter Girolami, CEO of SourceMaker, lighting was never simply a technical discipline. It was part of his upbringing. Growing up in New York in the 1960s and 70s, he recalls being brought to film sets by his father. One early memory, watching a car stunt unfold with meticulous coordination, left a lasting impression. “I was glued to it,” he says. “Even as a small child, it felt larger than life.”

Early Influences and a Foundation in Light

His father, a gaffer, built custom lights in the garage to supplement his work on set. Girolami watched those fixtures being assembled at home and later used in production. His mother was an artist who used the same lights to illuminate paintings at the dining room table. According to Girolami, dual exposure, technical precision on set, and artistic application at home shaped how he understood light from the start. It was both a tool and a language.

By the time he began working professionally as an electrician and later a gaffer, lighting challenges felt familiar rather than abstract. From his perspective, longstanding problems in the industry were not simply inconveniences; they were opportunities for refinement. “It’s a visual thing,” he explains. “You rely on what you have seen before to solve what’s in front of you.”

A Defining Challenge and the Start of Innovation

One pivotal moment, Girolami recalls, came while shooting in a vast, multi-story interior. The production needed to illuminate three levels simultaneously without overwhelming the space with equipment. The solution at the time, he explains, involved bouncing light into a weather balloon to create ambient fill. The concept stayed with him. Years later, an internally lit balloon was used for a special event in the United States. It was at this moment that he saw the potential, but also the limitations.

Early balloon systems, he explains, lacked durability and control. According to him, materials degraded under ultraviolet exposure, and round shapes made it difficult to shape or block light precisely. For film crews working in architecturally sensitive environments, such as cathedrals, museums, and historic landmarks, these constraints mattered. Rather than accept those compromises, Girolami says he began experimenting.

What started as a winter weekend project evolved into SourceMaker, the company he now leads as CEO. SourceMaker designs and manufactures specialty lighting tools for film, television, and commercial productions all over the world, with a focus on large-scale environments and controllable soft light solutions.

Engineering Control and Efficiency on Set

 “I drew on my early exposure to fabrication and started researching stronger materials, eventually adapting sailcloth reinforced with reflective layers to improve strength and longevity. I also reimagined the geometry of the balloon itself.”

By introducing square and rectangular designs, often referred to in the field as cubes and cuboids, he created fixtures that could be angled, skirted, and shaped with greater precision.

“The problem wasn’t just getting light into space,” he says. “It was controlling it. That control has practical implications. In expansive locations such as train stations, churches, stadiums, and even the open sea, conventional lighting often requires extensive rigging, frames, and grip equipment.” According to Girolami, that approach can increase setup time and introduce logistical complexity.

“By contrast, balloon systems are designed to integrate directly into the architecture,” he says. “This reduces the amount of gear on the floor and allows productions to begin sooner and also gives the director and cinematographer more flexibility to move and adjust from shot to shot with minimal effort.”

Producers and location managers, he notes, appreciate solutions that minimize disruption. “If everything is up and ready before the crew walks in, the day moves differently,” he explains. From his perspective, efficiency is not only about cost but about preserving creative momentum.

Expanding the Toolkit Through Practical Design

SourceMaker’s portfolio extends beyond balloons, with the creation of the original LED Blanket Light designed for high output while remaining portable, addressing another recurring production challenge: mobility. “Speed wins when it comes to production and budgets,” Girolami says. “The LED Blanket Light is engineered to be extremely lightweight to roll and deploy quickly, offering crews flexibility without sacrificing intensity.” They also offer high-output lighting tubes and ladderlights for backings.

Throughout the evolution of these products, Girolami maintained a hands-on approach, often testing prototypes on his own jobs. After an injury limited his ability to continue full-time set work, he devoted himself more fully to product development, refining each iteration through direct collaboration with gaffers and cinematographers. According to him, that ongoing dialogue remains central to the company’s philosophy.

A Shift in Perspective, A Consistent Mission

For Girolami, the mission has remained consistent: solve problems others have come to accept as routine. He explains innovation as a process of continuous adjustment, new materials, new shapes, and new applications.

Decades after those early family days on set, lighting remains integral to who he is. What has changed is the vantage point. As CEO of SourceMaker, Girolami no longer solves problems from behind the camera alone; he engineers tools that enable others to do so. In an industry defined by visual storytelling, his work operates just out of frame, shaping the light that makes each story possible.
