Product Overview

What This Piece Is

A hand-polished reflective ball in 126mm diameter, designed for film and television visual effects work. The surface is treated over 20 times to maintain specular reflection and accurate gray scale, meeting professional standards through long-term testing. Made from a durable material with a smooth finish, it serves as a light reference tool when used with 18% gray paint. Kapur produces it to your order, ships within 15 days at most, and includes tracking for FedEx, DHL or similar courier services. Each ball has a 1/4UNC thread for tripod or handle mounting.

Key Benefits

  • 126mm diameter available for precise lighting reference in studio and on-location shoots
  • Surface treated over 20 times to maintain high specular reflection and consistent finish
  • 18% gray scale accuracy verified through long-term testing for reliable light measurement
  • 1/4UNC thread on ball and base rod allows secure mounting on tripods or handles
  • Shipped within 15 days at most with tracking provided via FedEx, DHL or similar
  • Handmade construction with slight paint or finish variations that do not affect performance
Who It Is For

Buyers and Specifiers

  • Film and TV production crews needing reliable visual effects tools
  • Visual effects artists and digital compositors requiring accurate light data
  • Photographers working with HDR and reflective lighting techniques
  • Cinematography schools and training programs teaching lighting theory
  • Independent filmmakers and content creators using affordable, professional-grade tools
  • Studio owners and rental houses stocking reusable lighting reference equipment
Problems It Solves

What It Fixes

  • Fixed-size reflective balls in standard kits do not match exact lighting needs, so this is made to order
  • Inconsistent gray scale or reflectivity in low-cost balls leads to inaccurate HDRI captures
  • Lack of reliable mounting options for reflective spheres during shooting
  • Unclear delivery timelines delay production schedules, so delivery is guaranteed within 15 days
  • No tracking or courier visibility for small high-value items, so tracking is included
  • Handmade items may have minor finish variations, but these do not affect function

Comparison

How It Compares With Other Options

An honest read on the trade-offs, so the material decision is made before fabrication starts.

Standard chrome ballChrome offers higher reflectivity but no gray scale; this ball provides both reflectivity and 18% gray for light measurement
Plastic reflective ballPlastic is lighter and cheaper but scratches easily and loses reflectivity faster; this ball uses a more durable surface
Painted metal ballPainted surfaces degrade under UV and handling; this ball has multiple surface treatments to maintain finish
Glass reflective sphereGlass is fragile and risky to ship; this ball is made from a durable material with no breakage risk
