A term from cinematography and camera work.
Technical Characteristics
As a cinematographer, 4x5.65 filters are my most important tools for light control on set. Especially for exterior shots, I use graduated ND filters to darken the sky while still retaining detail in the shadows, without having to make corrections in post-production. The large filter surface gives me the flexibility to work even with extreme wide-angle shots without vignetting. The 4x5.65 filter is a process in film production. A term from camera work.
Areas of Application
For me, 4x5.65 filters mean creative control directly on set – I can establish the image mood with the cinematographer during the shoot, instead of leaving everything to post-production. For example, if we need a dramatic sky for an emotional scene, we achieve that more authentically with the right filters than with digital effects. These "in-camera effects" give the image an organic quality that the audience perceives subconsciously. High-quality 4x5.65 filters are an investment of several thousand euros per set, but they save costs in post-production in the long run. If the cinematographer already achieves the correct exposure and color balance on set, this significantly reduces grading time. I need to factor in enough filter sets for multiple camera units during equipment planning, as these often work in parallel.
