The Ultimate Diffusion & Bounce Test


Matt Porwoll | Cinematographer


There is a huge chasm between knowing lighting tools and knowing them intimately. Regardless of the approach, it takes a long time and a lot of experience to get to the latter. There is a wide array of options on the market, so how do you know what to use and when? I have been shooting for some time now, and assisting those better than me for even longer. I have had the opportunity to work with a wide array of lights and lighting augmentation, but its only been a few items at a time, sometimes spread over many months (or years) before seeing them again. Many cinematographers have their go-to approach to bouncing and diffusing light by always keeping a small selection of materials in their kit. Oftentimes, these were chosen because of what’s available. Other times, we hear its good, so we use it. But unless you’ve had a lot of practice and seen the side-by-side effects of each, it can be hard to know what would work best in a given situation. Because of this, I decided to conduct an in-depth test of various diffusion and bounce materials centralized in one location in a controlled environment.
