Appendix 5 Kodak Color Science
Cintel and Kodak have joined forces to improve Motion Picture Film Scanning by incorporating Kodak Color Science
into the diTTo data scanner. These improvements fall into three areas –
• Scanner Calibration
• Display Management
• Workflow Enhancement
Scanner Calibration:
Every diTTo scanner will be factory calibrated using Kodak’s Scanner Calibration Target Film and Kodak Motion
Picture Services (KMPS). The target film is scanned on diTTo during the final phase of the System Test cycle and the
resulting files sent to KMPS. These files are then analysed to produce Colour transform data which is used back at
the Cintel Test department to fine-tune the diTTo scanning path.
This factory calibration ‘loop’ will provide complete piece of mind regarding motion picture scanning. Any doubts
regarding the accuracy of the scanner optical path and image reproduction are eliminated.
These calibrations provide pre-set masking values for the three Kodak base stocks.
The 5217 film stock setting covers the Vision2 and Vision3 family of negative films.
The 5274 film stock setting covers the Vision family of negative films.
The 5242 film stock setting covers the intermediate film.
Display Management:
diTTo will optionally include the Kodak Display Manager (KDM) system to emulate the look of motion picture film in
the ‘Playback Viewer’.
The KDM option includes a monitor calibration probe which ensures that the diTTo GUI monitor is accurately
displaying the image content.
Utilising patented film emulation technology, this custom version of KDM will allow diTTo customers to pre-visualize
what their scanned film will look like when Printed by invoking different Look Up Tables (LUT’s).

Data generated via the characterisation is
analysed and used to generate a colour
transform that will ensure that each
scanner is calibrated to accurately record
the vast colour gamut associated with
colour negative films.
