13.5 SHUTTER settings
You can select your preferred shutter unit: Shutter angle converts exposure time into
the angle of a virtual rotating mirror shutter as in film cameras.
Note: A fixed angle creates varying exposure times with varying frame rates. You can
set angles from 5.0 to 356.0 degrees.
Exposure time shows the effective sensor exposure time. With varying frame rates, it
remains identical and can be set from 1/25 to 1/8000 seconds.
Note: Maximum exposure time with a given frame rate is 1/fps, with a limit of 1/25s.
For constant exposure time over the full range of used frame rates, set it to 1/(highest
used frame rate).

13.7.8 LOOK parameters
A look file contains different parameters for image alterings.
User-defined looks may contain a non-editable 3D LUT instead of video
parameters. Import of looks with 3D LUTs requires the premium license.
HOME > LOOK > SET LOOK > SET PARAM.
NOTICE
Slope, Offset, Power, Saturation affect ASC CDL images under Log C.
Black Gamma, Gamma, Knee, Saturation, Saturation by Hue affect VIDEO images.
ASC CDL parameters are applied to the image before VIDEO parameters. Please
refer to the ARRI white paper on color parameters (for download at www.arri.com).
Note: All look transforms, including ASC CDL, are applied in the conversion from Log
C to Video color space. When you choose Log C as gamma for an image path, the
clean Log C image is routed to this path.
Home screen 95
13.7.8.1 ASC CDL Transforms
The American Society of Cinematographers has specified a set of transforms that
have become a standard in postproduction. They are determined by slope, offset,
power and saturation (applied in that order).
All these parameters are based on simple color manipulations (multiplying with a
factor, adding an offset, raising to an exponent). Noted as "Color Decision List" (ASC
CDL), they offer an exchange format for basic look transformations between color
correction systems and editing tools by different manufacturers.
The ALEXA Mini image processing applies ASC CDL transforms to the Log C
encoded image. This allows manipulations such as exposure correction or bringing
down highlights, before the picture is converted to the display color space with its
steeper contrast curve.
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.
13.7.8.2 3D LUT and video look parameters
Via 3D LUT (lookup table), the camera generates a Rec 709 video image from Log
C data. Next to the ASC CDL parameters, which apply to the Log C image, the
camera also offers a set of video look parameters (VLP) for tone mapping and color
transformation of the rendering 3D LUT.
VLPs determine knee, black gamma and the gamma of the tone map curve, which
qualify the contrast of the output image. They also include values for saturation and
the saturation by hue for six color vectors (green, yellow, red, magenta, blue, cyan).
Whatever the adjustments, the underlying 3D LUT always converts Log C to Rec 709
color space.
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.
96 Home screen

1
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.

13.8.1 EI technical details
The Exposure Index (EI) is the applied sensitivity of the camera. The ALEXA Mini
has a base sensitivity of 800 ASA. This means that the dynamic range is almost
evenly distributed above and below neutral gray with low noise in the shadows and
clean, smooth clipping behavior in the highlights. Due to its high dynamic range, the
ALEXA Mini's sensitivity can be set from 160 to 3200 ASA in steps of 1/3 stops while
maintaining high image quality:
Applying the exposure indexes at the extremes of the range will nonetheless have an
influence on the images.
At low exposure indexes, such as 160 ASA, the dynamic range below neutral gray
increases, reducing noise even further. At the same time, the dynamic range above
neutral gray is slightly reduced.
Highlight clipping itself is not influenced by this, but the shoulder of the gamma
curve will get slightly steeper, reducing the smoothness of the change from almost
overexposed to overexposed.
At high exposure indexes, such as 1600 ASA, the images behave in the opposite way.
Noise is increased, which makes it important to judge shadow detail, while there will
be even more headroom in the highlights:
