ARRIRAW controls

The default values for an ARRIRAW clip come from the metadata stored in the recorded media clip. In addition to a resolution selector, you may also select the file Frame Rate from a pulldown selector. Color Temperature operates in a familiar fashion, based on the Kelvin scale. Move the Green/Magenta Tint slider in a negative direction (left) to add a magenta cast to the image. Move it right to a positive value and the image will have a green cast.

ARRI’s ALEXA line of digital cinema cameras use a sensor design optimized for an ISO of 800. There is no separate exposure control, so adjusting the ISO slider will make the image brighter (higher ISO value) or darker (lower ISO value).

The image from the Bayer-pattern sensor is demosaiced using a software algorithm, which can be updated by the camera vendor for an improved RGB conversion in the future. The ARRIRAW controls currently feature five variations of ARRI’s conversion.

The default setting for Sharpness and Detail is 0. Increasing the Sharpness value will artificially enhance the sharpness of the image. Decreasing the Detail slider will soften the image detail natively recorded from the sensor. Finally, there’s an ND filter pulldown based on what was recorded in-camera.

In addition to the color space options already mentioned, the ARRIRAW controls include a Custom setting. When you select Custom for color space, more choices become available, including several DCI formats. These would be typical of projects shot for theatrical projection.
