A show’s look is a powerful storytelling cue that helps orient an audience to a story’s intended genre and tone. In general, comedies look sharper, bluer, and more immediate. Dramas look more diffused, warmer, and past tense. It is the cinematographer’s responsibility to create a look that is consistent with the program’s genre from the very first frame. In this article Barry Braveman looks at how this can be achieved.
The first order of business is setting the camera master detail (DTL), which affects perceived sharpness by placing a hard edge around objects. When DTL is set too high objects acquire a plastic look that folks associate with video. When DTL is set too low images appear soft and lack definition.
Many cameras’ default settings (especially Sony models) contribute to a harsh brassy look. Tastefully tweaking these values or utilizing a camera filter can help alleviate this.
Light and Glass
While many physical filters can be approximated in software, the delicate interplay of light through and around a glass element is not a process that lends itself to a general solution. A beam of light interacting with the thousands of interspersed elements inside a modern diffusion filter, for example, impacts the character, colour, and direction of the beam in myriad complex ways.
The complex interplay of light passing through a physical glass filter cannot be recreated.
The actual impact of a physical glass filter depends on many factors such as the lens’ aperture, strength of backlight, and whether the point sources in frame are sharply defined. These elements can significantly affect the look and feel of a scene. Some filters like a polarizer or graduate can add detail to a scene that wouldn’t be present otherwise.
