bullet02It is possible to set [ARRI LogC3] in the Photo Style display restrictions in the Photo Style setting of the [Custom] ([Image Quality]) menu.

bullet02Functions are restricted as follows when [ARRI LogC3] is set:

– Cannot record with the [MP4] recording quality.

– Cannot record with the [MOV] [420/8-L] recording quality.

– Cannot record with the [Apple ProRes RAW HQ]/[Apple ProRes RAW] recording quality.

– ISO sensitivity is restricted to a lower limit of 160 (lower limit of 320 when [Dynamic Range Expansion(Log)] is set) and an upper limit of 51200.

– The luminance level setting is fixed to [64-940].

– [Master Pedestal Level] is not available.

– The only image quality adjustments available are [Sharpness] and [Noise Reduction].

character_diamondISO Sensitivity When [ARRI LogC3] Is Set

The lower limit of available ISO sensitivity is [160], and the upper limit is [51200].

When [Dynamic Range Expansion(Log)] is set to [ON], the lower limit is [320].

bullet02Reset the exposure if necessary when ISO sensitivity changes.

character_diamondExposure When [ARRI LogC3] Is Set

The log characteristics of [ARRI LogC3] comply with 800 ASA (EI 800), described in “ARRI_ALEXA_LogC_Curve_in_VFX.pdf” released by ARRI. The log characteristics of [ARRI LogC3] on this camera do not depend on the ISO sensitivity settings.

However, according to the Exposure Stops values defined in 800 ASA (EI 800), there will be the equivalent of 2.6 stops worth of clipping when [Dynamic Range Expansion(Log)] is [OFF] and 1.6 stops worth of clipping when [Dynamic Range Expansion(Log)] is [ON].


Refer to the following for “ARRI_ALEXA_LogC_Curve_in_VFX.pdf”:
