Product Overview

What This Piece Is

A hand-crafted reflective ball in polished or 18% gray finish, available in diameters of 60mm, 126mm, 200mm, or 250mm. Designed for film and television production, the surface is treated over 20 times to maintain specular reflection. The polished version reflects the environment with high clarity, while the gray version provides a consistent 18% reflectivity for lighting reference. Each ball has a 1/4UNC thread for mounting on tripods or handles. Kapur produces it from your specification and ships within 15 days, with tracking provided. Delivery via FedEx, DHL or similar included in the economic shipping rate.

Key Benefits

  • Available in four standard diameters: 60mm, 126mm, 200mm, 250mm to suit different lighting setups
  • Polished surface treated over 20 times to maintain high specular reflection for accurate HDRI capture
  • 18% gray finish tested for professional accuracy in lighting reference and exposure measurement
  • 1/4UNC thread on ball and base rod allows direct mounting on tripods, stands, or handles
  • Delivered within 15 days at most, with tracking provided once shipped
  • Shipping via FedEx, DHL or similar included in the economic transport price
Who It Is For

Buyers and Specifiers

  • Film and TV production crews sourcing physical lighting reference tools
  • Visual effects supervisors needing calibrated reflective spheres for HDR capture
  • Photography studios integrating reflective balls into product or set lighting
  • Lighting technicians setting up studio environments with accurate exposure references
  • Digital artists and 3D modelers requiring real-world lighting data for rendering

Problems It Solves

What It Fixes

  • Fixed-size reflective spheres are not always available in the exact diameter needed for a shot
  • Low-reflectivity or uneven surfaces distort HDRI capture and affect lighting accuracy
  • Lack of standardized 18% gray reference spheres leads to inconsistent exposure readings
  • Mounting issues with non-threaded or incompatible bases disrupt setup speed
  • Unclear delivery timelines delay production schedules on tight shoots
  • Shipping costs and tracking are not included in basic tool purchases, causing delays

Comparison

How It Compares With Other Options

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

Plastic reflective ballPlastic is lighter and cheaper but degrades under UV and heat, while metal maintains reflectivity over time
Uncoated metal ballUncoated metal shows surface imperfections and uneven reflection; Kapur's treated surface ensures consistent specular response
Standard 18% gray cardGray cards are flat and limited to one surface; the ball provides 360-degree reference for lighting and exposure
Commercial HDRI sphere kitsMany kits use low-precision finishes; Kapur's version is tested for professional accuracy and durability
