Dalsa Origin - Technical Details

Technical Details

The camera has a resolution of 4K (4096×2048). Beyond resolution, the camera was unique in its ability to capture at a very high bit depth. The camera output an uncompressed, RAW Bayer pattern 16-bit image, which was considerably higher than other cameras which are limited to 8, 10 or 12 bits. This resulted in a linear exposure latitude equivalent to more than 13 stops. The images created by the Origin II camera were widely regarded as having more visible resolution and more dynamic range than any other digital cinema camera.

The final configuration of the camera could run 1–30 frames per second. The Origin II camera featured an optical reflex viewing system with rotating mirror similar to 35 mm film cameras and uses standard PL mount 35 mm film gate lenses. The camera was approximately the same size and weight as an average 35 mm film cameras with a 400' magazine.

The camera output raw data to an off board storage unit at a rate of approximately 400 megabytes per second. The Origin II connected to the storage unit by an extremely rugged, thin and flexible mil-spec fiber optic cable. This fiber cable can be run for over a mile without any signal degradation or repeating. The storage unit that has been used most often was the Codex Digital recorder, which could hold about two hours of uncompressed 4K camera RAW footage. In January 2008 S.Two began shipping the DFR4K recorder, which can also capture images from the Origin II camera and similar 2K and 4K models. S.Two also manufacturer a system of 4K workflow products that were compatible with the Origin II camera's 4K images.

Famous quotes containing the words technical and/or details:

    A technical objection is the first refuge of a scoundrel.
    Heywood Broun (1888–1939)

    Patience is a most necessary qualification for business; many a man would rather you heard his story than granted his request. One must seem to hear the unreasonable demands of the petulant, unmoved, and the tedious details of the dull, untired. That is the least price that a man must pay for a high station.
    Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
