Wrock

You'll find it on every low-budget set: the Wrock. Styrofoam or foam board, white coated, inexpensive to acquire and reliable to use. It reflects light diffusely — not hard like a silver reflector, not as soft as tulle or diffusion. The Wrock sits somewhere between both worlds and does exactly what you expect from it: gently catch existing light and redirect it into the shadows.

In practice, you use the Wrock as a key reflector indoors or as a fill reflector in sunlight. It's worth its weight in gold, especially in portraiture — the reflection looks natural, not too cool like silver, and the light quality remains soft enough for faces. Size plays a role: a large Wrock (1.5 × 2 meters) fills the entire shadow of a person, while smaller variants are precisely positioned at eye level. The diffusion is even — no hot spots like with hardened reflectors, but also not as matte as pure diffusion.

The biggest advantage remains its robustness and price. A Wrock can withstand multiple productions, is easy to transport, and doesn't look pretentious when it's on set. It's simply part of the equipment, like a C-stand. However, Wrock is not universally applicable. In harsh sunlight, you sometimes still need the hardness of a silver reflector to bounce enough light back. And in very bright environments, the Wrock loses effectiveness — the white surface only reflects what hits it.

An important distinction from diffusion: The Wrock reflects light, while diffusion scatters it by passing through. This means you lose more light intensity with pure diffusion. Therefore, the Wrock is often the more economical solution in a setup. A real blessing for digital cameras with low light sensitivity — every stop counts. I've often stood next to a DoP who combined Wrock and tulle: Wrock as the primary reflection, tulle behind it for the final softening. It works, costs almost nothing, and looks like expensive lighting design later.
