Some criteria for defining the nature of Digital Cinematography
Friday, July 22, 2011
I want to set down here that though Film is seen as having superior resolution to data cinematography, (it is universally agreed to require scanning at 6k resolution to make it useful for entry into the digital domain) when we use completely photochemical pathways to deliver a moving image to the cinema, after having gone through all of the processes required to get to the cinema going public (including the often low resolution of the lenses on the projector itself), the image the audience sees is only of 1K resolution – and that’s only if the audience sits at a distance equal to no more than two screen heights away from the screen. Like it’s name suggest, 2K cinema projection begins at 2K which is 4 times the resolution of the photo-chemical display chain.
My suggestion for some parameters for the definition of Digital Cinematography are:
a) it’s optical pathway is 35mm or above (next generation cameras at NAB 2011 are at this standard)
b) like one of its predecessors, film, it holds the image in a latent state until an act of development (or rendering) is applied - but unlike film is non-destructive of its prior material state
)
c) it’s capture mechanism generates a nondestructive, non-compressed data pathway from which an image can be reconstructed (but is distinguished from digital video who’s sole intent is to generate images in a compressed manner from less than 35mm optical pathways), again new next-generation cameras at NAB require this later kind of data handling
d) it generates a progressively based image flow as opposed to an interlaced image flow (one full frame of information at a time rather than a field-based workflow)
e) Both the last two qualities are also base characteristics of many developing digital technologies – for instance real time mapping of environments require a capture of at least 3 infra-red imaging sources (Cameras) running at 25 fps at a reasonable resolution – therefore digital cinematography is about more than just capturing images.
