The SkyPanel X already has terrific color quality (CRI, TLCI, TM30, etc.), but the ARRI ALEXA Modes take this a step further by calibrating the SkyPanel X to the spectral senstivity of the ALEXA ALEV 3 and ALEV 4 sensors. There are three ALEXA Modes: ALEXA Standard Mode, ALEXA VariFan Mode, and ALEXA High Output Mode.
