The Best Uses for Poly Boards and where to buy them.

What Are Polyboards (Photography)

  • Polyboards (also called poly boards or foam polyboards) are rigid, lightweight panels made from polystyrene (foam), commonly sized around 2400 × 1200 mm (4′×8′) and approximately 50 mm thick.
  • One side is painted white (for light bounce), the other black (for negative fill); this dual surface makes them a powerful, low-cost light modifier.

Why Photographers Use Polyboards

  • Bounce light: Use the white side to reflect studio or natural light into shadow areas and soften facial features.
  • Negative fill: Use the black side to absorb unwanted bounce light and sculpt depth—helping avoid flat lighting in white studio spaces.
  • Easy to customize: Paint or tape one side black; most arrive both-sided white, making them versatile and durable.
  • Affordable and portable: Widely available in hardware stores, they’re cost-effective and easy to move or store.

How to Set Up Polyboards in Studio

Creating V-Flats

  • Tape or hinge two boards A-frame style to form a V-flat: white sides inward for reflection, black sides inward for contrast and shadow control.

Supporting Your Polyboards

  • Use purpose-built stands or DIY hacks like bike stands or heavy-duty clamps to keep boards upright—you’ll need bracing to prevent wobble.
  • Velcro or hinges between sheets make setup easier if you don’t want permanent fixtures.

Practical Photography Uses

Portraits & Beauty

  • Place a white polyboard just out of frame to bounce light under the chin or fill shadows on one side of the face for flattering, soft illumination.
  • Use the black side to sculpt shadows and add contrast near the cheek or hairline.

Product & Fashion Shoots

  • Use white polyboards behind or beside the product or garment to avoid unwanted reflections and soften transitions.
  • Black boards can help isolate shape and create dramatic lighting effects.

DIY Tips & Tricks

  • Size & Thickness: Choose at least 50 mm (2″) thick (and ideally 2400 × 1200 mm) so boards remain sturdy when upright.
  • Painting: Use flat or low-sheen paint. A grey undercoat improves finish and prevents warping. Most boards need ~2 coats per side (~350–500 mL per coat).
  • Handling: Seal edges with tape to guard against dents and wear.
  • Packing: Transport flat or hinged; flat stacking risks bending, hinged V-flats store more securely.

Quick Setup Guide

  1. Position your strobe or continuous light on one side of your subject.
  2. Set a white polyboard on the opposite side at about waist/chin height angled toward the subject to fill shadows.
  3. Black polyboard placement: Where you want deeper contrast—place black inward to block light.
  4. Capture a test shot, then adjust board position or angle to refine shadow and highlight distribution.

Beginner Pitfalls to Avoid

  • Mixing software references—only focus on photography use.
  • Over-thin boards (<50 mm)—leads to sagging or collapse.
  • Skipping reflector/clamp support—unstable boards distract and compromise safety.
  • Using glossy paint—reflective finishes bounce unintended glare.

Where to Buy or Hire Polyboards in Australia

  • Foamboards Australia: Foldable V-flats with dual-color surfaces.
  • Lumoz (Melbourne): Offers thick polystyrene boards (~40–50 mm).
  • Camera Hire Australia: Rent polyboards for short-term shoots.
