For all of you camera assistants who have been asked to DIY build your own variable ND filter with two polarisers, here is a plug-and-play solution: The Cinefade VariND just needs to be connected with an LBUS cable, no calibration required and can be remotely controlled from a cmotion cPro lens control system!
Thoughts? Comments? Has anyone used this system for interior to exterior shots or just to speed up ND changes, especially when working with RED cameras without internal NDs?
