Cine EI Pushback From Inmates in an Asylum

Sony’s Cine EI – just like ARRI, Canon, Panavision, Blackmagic, RED, Kinefinity and every other cinema camera manufacturer’s EI – allows you to prioritize shadows or highlights by allocating more stops of dynamic range, or latitude, above or below middle gray, and letting the photographer preview its effect using monitor LUTs, giving an indication of how the shot will appear after grading. 

Unlike traditional ISO, which applies gain to the signal as ISO is increased, reducing dynamic range, EI is just metadata, meaning that increasing or decreasing it does not reduce dynamic range – it just redistributes it. Yet these sideshow circus freaks in the forums pretend that it’s no different from the traditional ISO found in consumer digital cameras.
