Patrick B. Posted September 15, 2019 Share Posted September 15, 2019 I’m curious why simultaneous dual gain sensor architectures a la the Alexa Alev III aren’t more common in smaller cameras. This allows a low and high ISO signal to be combined for one HDR image. It seems that in ten years most cameras still can’t match the Alexa for sheer video dynamic range, yet CMOS sensor technology has obviously evolved in many ways. Is there a limiting factor like size/heat, a patent, or maybe otherwise? Perhaps it’s just that the average consumer is more interested in increased resolution? We now are seeing the switchable dual gain architecture used more, but I’m not aware of lower end cameras using simultaneous dual gain.
