Incoming Light - Lens Options

• Although not as diverse as the 35mm format, many options are still available

• With the interchangeable lens mount system, any lens system is valid

• For still lenses we have the standard Mamiya 645 and Hasselblad designs

• Large format shift tilt systems create interesting effects

• In the 3D realm, the Zepar system is truly a unique offering

How RAW is RAW?

•Vision Research’s version of RAW is fairly straight forward

•Sensors, in their natural state, create a very rough image

•To correct this, VRI applies only two corrections in camera:

– FPN (Fixed Pattern Noise), aka Offset

– PRNU (Photo-Response Non-Uniformity), aka Gain

•And that’s it.

CineMag – fast, non-volatile storage

•After the camera’s image corrections, CineMag stores the data

•Save speeds of 800Mpixel/second

•This is achieved by unique management of the flash array

•Each pixel only has a single 14-bit color value, either R, G, or B

•Color interpolation is processed in post, not in camera

•This assures maximum flexibility in the post environment

CineStation – the bridge to post-production

•CineStation is essentially the ‘reader’ for the CineMag

•Using 10gig Ethernet, files are moved from the magazine to permanent IT based storage.

•During this transfer, several file formats are selectable:– Cine (either RAW or Interpolated)– DPX– TIFF– DNG

•However, VRI recommends storing this data as CineRAW, which retains only the sensor data, thus giving the edit house or archive facility an open field of options during post, or in the future.
