 LOOKS

Look and gamma settings:

ARRI 709: Renders the video image according to the ITU.R-BT709 standard, for most
accurate color reproduction on standard broadcast monitors.
ALEXA Classic 709: Matches the color reproduction of ALEXA Mini to the ARRI ALEXA.
Commercial: Renders the image brighter for smoother skin tones.
Landscape: Applies a steeper contrast curve to the image.
LCC 709: Low Contrast Curve look that keeps more details in highlights for color correction purposes.
TV-neutral
TV-warm
Vibrant: Boosts color saturation except for red and yellow (skintone protection).

Slope, Offset, Power, Saturation affect ASC CDL images under Log C.
Black Gamma, Gamma, Knee, Saturation, Saturation by Hue affect VIDEO images.

  • Slope: The linear section of the Log C curve is equivalent to the gamma of a negative film stock. The Log C curve has a default gamma of approximately 0.51 (adjustable via slope parameter).
    A slope value of 1.2 will have a similar effect as using negative stock with a gamma of 0.6 (= 1.2 * 0.5). A value below 1.0 will lower the gamma accordingly.
  • Offset: This most intuitive CDL parameter has a similar effect as increasing the exposure index on the camera. If you are familiar with the motion picture print film process, it’s the same as printer lights.
  • Power: Via power you can adjust the mid tones, similar to the Gamma parameter in video color grading. A power value below 1.0 will increase, a value above 1.0 willl decrease the mid tone brightness.
  • (Log) Saturation: This parameter affects the saturation of all color components in the Log domain. A value of 1.0 represents the default saturation.
  • Knee: The knee parameter controls the transition of mid-tones into highlights. Values below 0.5 (default) produce harder highlights, higher values soften them. Knee is applied to all channels equally (master control). It has no effect on the mid gray level.
  • Black gamma: The black gamma controls the shadow detail in the image. Values below 0.5 (default) bring down, higher values brighten the blacks. Black gamma is applied as master control. It only affects the mid gray level for very high values.
  • Gamma: This setting can be used to brighten or darken the mid tones, while leaving the black and white level unchanged. Values below 1.0 (default) will darken; higher values will brighten the image.
  • (Video) Saturation: The VLP set also includes a saturation control, with a similar effect as the ASC saturation control. A value of 1.0 represents the default saturation.
  • Saturation by Hue: This parameter set allows you to control the saturation for six color vectors (red, yellow, green, cyan, blue, magenta) independently.

SPECIAL NOTES

  • Never touch the sensor.
  • Do not leave the antenna connector open during operation or transport. The radio module inside could be damaged by electrostatic discharge.
  • Never connect the EVF cable to any other connector on the camera than the EVF connector. This may cause permanent damage.
  • Do not cover the viewfinder proximity sensor. Please note that covering the proximity sensor located within the eyepiece with tape or similar, can cause an irreversible burn-in on the OLED display.
  • Card ejection during erasure, or interrupting the camera power supply, may render the card unusable.
  • The image stabilizer of EF lenses is currently not supported.
  • The frame rates for sensor and project rate must match to enable audio recording.
  • ALEXA Mini cannot record more than 400 clips on a single card. Please note that the camera gives no further information but just refuses to record more clips.
  • File names longer than 28 characters (excluding extension) cannot be loaded by ALEXA Mini. Files with longer names will not be listed and cannot be used.
  • Only a limited number of camera files can be supplied on a USB stick: User Setups: 20; Look Files: 100; Frame lines: 100; License files: 100; SUPs: 20.
  • ALEXA Mini creates a file named “*_BIN.bin” (i.e. A001R3VJ_BIN.bin) when recording. This is used for internal data management; you may ignore this file.
  • The framegrab to USB function is only available when the camera is in standby mode. Framegrabs are always stored in HD 1920×1080 resolution and use the gamma setting of the SDI output. Framegrabs do not work in 4:3 2.8K recording mode.
