INT to EXT Steadicam shot
Shots where the camera travels from an interior to an exterior location with large lighting differences are now possible without having to 'ride the iris' and affecting depth of field.
The variable ND filter adjusts exposure when transitioning between the bright and dark environments, allowing the DP to maintain a constant shallow depth of field inside as well as outside (read more).
Faster ND changes
Instead of manually changing traditional Neutral Density filters, a variabel ND filter allows for faster and more precise ND density changes in third and full stops directly on the filter without a lens control system.
