Product Overview

What This Piece Is

A handcrafted visual effects HDRI ball in 60mm diameter with a precisely calibrated 18% gray surface, designed for film and television lighting reference. The surface undergoes more than 20 treatment stages to maintain consistent specular reflection and accurate gray scale. Made to order from your specification, it ships within 15 days with tracking via FedEx, DHL or similar. The ball features a 1/4UNC thread for tripod or handle mounting and is suitable for use in studio lighting setups, on-location shoots, and digital environment mapping.

Use Guide

Ordering and Care

  • Use the 60mm ball in close-up setups or handheld lighting reference
  • Mount securely on a tripod or rig using the 1/4UNC thread
  • Avoid abrasive cleaning; wipe with a soft cloth and water if needed
  • Store in a dry place to prevent dust or moisture from affecting the surface
  • Use in controlled lighting environments to ensure accurate HDRI capture
  • Check thread and surface before each use to ensure no damage from prior handling
Comparison

How It Compares With Other Options

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

Mirror-polished chrome ballChrome reflects light with high gloss, while gray ball provides neutral 18% reflectivity for accurate lighting measurement
Plastic reflective ballPlastic is lighter and cheaper but less durable and prone to surface degradation; fiberglass holds finish better
Painted metal ballPainted metal may chip or fade; fiberglass with multiple surface treatments maintains consistency over time
3D printed reflective ball3D printed balls have inconsistent surface texture; this ball uses precision molding and multiple treatments for uniformity
