12.6cm VFX Balls
12.6cm VFX HDRI Ball Chrome and Grey Ball
Chrome and grey captured at the same moment for HDRI stills
This 12.6cm set captures chrome and grey at the same time, which is the usual way HDRI stills are shot.
VFX Ball products are produced for film and television post production, where grey scale accuracy decides whether a CG element sits in the plate.
The ball surface is treated more than 20 times to hold specular reflection.
