20cm VFX Store Movie Shot Ball Grey Ball
20 cm VFX set supplies a chrome ball and a grey ball for on-set lighting and HDRI reference capture. The chrome ball carries a 3/8 UNC thread for tripod or handle mounting, while the grey ball uses 50 percent grey paint with 18 percent reflectivity. The set includes one horizontal pole, two telescopic handles and two ball bases, so a crew can place both reference spheres at the same camera position.
Key Benefits
- Chrome and grey spheres give two reference targets for lighting colour and reflection capture
- 3/8 UNC thread lets the chrome ball mount to a tripod or handle without adapters
- 50 percent grey paint with 18 percent reflectivity supports consistent exposure and colour checks
- Two telescopic handles extend from 22 cm to 47 cm for different working heights
- Set includes horizontal pole and two bases so both balls can be staged together
- 20 cm diameter gives a clear reference object without occupying too much floor space
Problems It Solves
- Separate balls handles and bases can be hard to source as one set
- A plain grey target without fixed reflectivity makes exposure checks inconsistent
- Chrome balls without a mounting thread are awkward to place on tripods
- Fixed handles cannot adapt to low or high reference positions on set
- Two spheres at different heights can give mismatched lighting and colour data
- Bare reference balls can roll or shift when bases are not supplied

- Finished pieces kept under protective film until they are packed
- Batch photographs sent for approval before the balance is invoiced

- Use the 22 cm telescopic handle for low positions and extend to 47 cm
- Set both the chrome ball and grey ball at the same camera reference position

- Keep the horizontal pole and bases together so the set is not split on location
- Protect the chrome surface and grey paint when moving the set between shots
Compared With The Alternatives
| Alternative | How this product compares |
|---|---|
| Separate chrome and grey balls | This set includes the pole handles and bases but the balls are fixed at 20 cm |
| Larger HDRI spheres | 20 cm is portable and quick to place while larger spheres may show more surface detail |
| Plain grey targets | The grey ball has stated 18 percent reflectivity which a generic grey card may not match |
| Non-threaded chrome balls | The 3/8 UNC thread allows tripod mounting but it limits placement to compatible fixtures |
