Dynamic range is a significant factor in the quality of both the digital and emulsion images. Both film and digital [dubious – discuss] sensors exhibit non-linear responses to the amount of light, and at the edges of the dynamic range, close to underexposure and overexposure the media will exhibit particularly non-linear responses. The non ...
Roll-off is also significant on audio loudspeaker crossover filters: here the need is not so much for a high roll-off but that the roll-offs of the high frequency and low-frequency sections are symmetrical and complementary. An interesting need for high roll-off arises in EEG machines. Here the filters mostly make do with a basic 20 dB/decade ...
Digital cinematography captures motion pictures digitally in a process analogous to digital photography.While there is a clear technical distinction that separates the images captured in digital cinematography from video, the term "digital cinematography" is usually applied only in cases where digital acquisition is substituted for film acquisition, such as when shooting a feature film.
The unique aesthetics of film lie in the way the image is captured, fundamentally distinct from magnetic tape video film or the image sensor of a digital camera. A basic photosensitive material consists of a "sandwich" structure comprising a transparent base, such as celluloid or glass , and a photographic emulsion containing photosensitive ...
The time and expense of film photography instills craft and patience; [19] pre-film even more so. Vintage film cameras offer a tactile, hands-on experience that feels more deliberate and engaging. Each film stock delivers a distinct and consistent aesthetic that is difficult to achieve in digital photography.
Consequently, photographers demanding higher quality in sectors such as weddings, portraiture and fashion where medium format film predominated were the last to switch once resolution began to reach acceptable levels with the advent of 'full frame' sensors, 'digital backs' and medium format digital cameras. Film camera sales based on CIPA ...
