Chrome and Grey Reference Balls for Film and VFX

A reference ball is a measuring instrument that happens to be shiny. If the chrome surface is uneven the environment map is wrong, and if the grey is not neutral the whole lighting solve drifts in grade. Our VFX spheres go through more than twenty surface processes to hold a clean specular reflection, and the grey has been set through repeated post production testing rather than picked by eye. Five diameters, from a 6 cm travel ball to a 30 cm exterior ball.

Проблемные места

Что не так с этими проектами

Проблемы

  • Garden gazing balls have uneven surfaces that distort the reflected environment
  • A grey that is not neutral pushes the lighting solve off in grade
  • Cheap chrome hazes after a few shoots and shows every handling mark
  • Mismatched chrome and grey pairs are hard to reconcile in comp
  • Balls without a proper mount shift on the stand between takes

Что нужно покупателям

  • A clean specular surface that survives repeated use on set
  • A grey that behaves consistently against the usual chart
  • Several diameters so the ball can be matched to lens and set
  • A threaded mount that holds position
  • Packing that protects the mirror surface in transit

Частые вопросы

Film and VFX Studios Questions

Which diameters do most crews buy?

20 cm and 25 cm are the common working sizes. 6 cm and 12.6 cm suit tight sets and travel kits, 30 cm suits wide exteriors.

Do you make half chrome half grey balls?

Yes, in the 25 cm size among others. They cover both references in one frame when there is no time for two setups.

How neutral is the grey?

It has been set through repeated post production testing rather than chosen visually. Shoot it with your usual chart and it will read consistently.

Как монтируются шары?

Threaded mounting so the ball sits solidly on a stand, a magic arm or a tripod head.

Can we order a full kit for several units?

Yes. Tell us how many kits and which diameters and we will quote them as matched sets.
