Highlights
Deep focus was once a novel cinematography technique, used by Orson Welles in 'Citizen Kane' to convey disorientation. In 1941, achieving this required immense effort due to lighting limitations. Today, filmmakers often aim for blur with wide-open apertures.
The speaker challenges the notion that one shouldn't shoot past f/11 due to diffraction, while simultaneously criticizing modern lenses for being 'too sharp.' They argue against theoretical filmmaking guidelines, emphasizing that images are subjective and the pursuit of technical perfection can stifle creativity.
While shallow depth of field is popular for its softening effect, the speaker highlights that higher f-stops (like f/16, f/32) can achieve a similar effect through diffraction, contributing to an artistically flat or 2D look. Deep focus at f/16 can bring rich detail and realism, offering an immersive experience that contrasts with modern CGI-heavy cinema.
The video questions the embrace of taller aspect ratios like IMAX if the detail is blurred, suggesting that deep depth of field complements new open-gate technology. It posits that the bokeh trend, driven by new equipment, might eventually fade, much like Cinemascope.
Beyond sharpness and depth, shooting deep focus with lenses like Zeiss can enhance color accuracy. The speaker notes that their pleasing video colors might be partly due to the accurate color rendition of their Zeiss lenses when stopped down. Ultimately, deep focus is described as 'filming on hard mode,' revealing imperfections but adding soul and personality, standing out from homogenized images.
