Adjusting The Light Source - Blackmagic Design Cintel Scanner Installations- Und Bedienungsanleitung

Focus Assist
Enables luminance peaking on your scanner's HDMI monitor output, plus the viewer inside
DaVinci Resolve's film scanner panel, which makes it easy to obtain optimum focus adjustments.

Adjusting the Light Source

These controls let you adjust your Cintel Scanner's light source to calibrate the optimal Dmin
density minimum. The Dmin density minimum is the minimum scanned value, plus the color
temperature of the scanned material. Adjusting the light source settings correctly will ensure
the best quality scans and make sure you are not clipping image data during the scanning
process. It's a good idea to check your light source settings when changing film to ensure the
quality of your capture.
Use the built in software scopes in DaVinci Resolve to help you set your light source to its
optimal level settings. The scopes can be opened in the media page by choosing Workspace >
Video Scopes > On.

light source and on the right, the status when calibration is successful
Light Source Master Wheel
The vertical light source master wheel is located next to the color wheel and adjusts the
intensity of the light source used to illuminate the film, raising or lowering the RGB channels all
at once. For typical negative film, this lets you adjust the black point of the film image, which is
the darkest part of the image. In negative film, this in fact corresponds to the highlights of the
film image. Adjust the light intensity to sit just above the typical Dmin value of 95, as measured
on the histogram of the video scopes, which guarantees that the highlights won't be clipped by
a Cineon-style LOG conversion. For positive film, simply adjust the master wheel so that no part
of the signal is being clipped.
Auto Black and Auto White Button
Analyzes the current frame displayed in the viewer and does an automatic adjustment to set
the black point for negative and inter negative using the framing bar area. For print and inter
positive film it uses the brightest highlight in the image area to set the white point, so key
selection of the frame is important. Alternatively, for positive film types you can use a punch
hole frame for maximum white to ensure all subsequent frames are compliant. For positive film
types, the 'auto black' button changes to 'auto white'.
