Apr 1 | 10:00 am 5:00 pm PDT

Join WiM, Birns and Sawyer, and our friends at Sony for a day of filtration education and networking at the Sony DMPC.  Mastering the art of filtration helps you capture the look and feel of your imagery in camera. This gives the cinematographer, in collaboration with the director control over the image in production. This class is aimed at folks in the camera department, directors, and producers who want to have a deeper understanding of this very important tool to enhance your artistic choices. 

We’ll be discussing polarization, diopters, diffusion, special effects filters and so much more.  Nancy Schreiber, ASC will be our special guest.
