What This Piece Is
A 250mm diameter visual effects HDRI ball in 18% gray, designed for film and television lighting reference. The surface is treated over 20 times to maintain precise specular reflection and consistent 18% reflectivity, meeting professional standards. Made from a durable material with a smooth finish, it is used to capture accurate light data in studio or on location. Kapur produces it to your order, with delivery within 15 days at most, and includes standard shipping via FedEx, DHL or similar. Each ball is handmade, and minor paint or finish variations may occur but do not affect performance.
Key Benefits
- 18% reflectivity calibrated for accurate light measurement in film and TV production
- Surface treated over 20 times to maintain consistent specular reflection
- 250mm diameter provides a large capture area for high-resolution HDRI mapping
- 1/4UNC thread on ball and base rod allows secure mounting on tripods or handles
- Handmade construction with minor finish variations that do not affect performance
- Delivery within 15 days at most, with tracking number provided upon dispatch
Buyers and Specifiers
- Film and television production crews requiring reliable lighting reference tools
- Visual effects artists integrating real-world lighting into CGI scenes
- Photographers and lighting designers working with HDRI capture
- Camera operators and gaffer teams setting up lighting rigs on set
- University and technical school instructors teaching cinematography and lighting
- Independent creators and content producers using professional-grade tools
What It Fixes
- Standard reflective balls lack consistent 18% gray calibration, leading to inaccurate lighting data
- Surface imperfections or inconsistent finishes in mass-produced balls affect HDRI accuracy
- Lack of reliable delivery timelines for custom lighting tools delays production schedules
- No standard thread size or mounting compatibility across different rigs and tripods
- Handmade items often have unpredictable finish quality, but Kapur ensures consistent performance
- Shipping delays or lack of tracking information disrupt on-set planning

- Check reflectivity regularly if used frequently in production
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 ball | Chrome has higher reflectivity but is not calibrated for 18% gray; used for specular highlights, not lighting reference |
|---|---|
| Plastic 18% gray ball | Plastic may scratch or degrade under repeated use; Kapur's ball has more durable surface treatment |
| Painted metal ball | Painted surfaces can chip or fade; Kapur's multi-treatment process maintains surface integrity |
| Mass-produced HDRI ball | Many mass-produced balls lack consistent 18% reflectivity; Kapur's version is tested for professional accuracy |
