1. A source device configured to compress color space representations for a hardware pipeline, comprising:
a sensor subsystem comprising a dual readout camera sensor;
a user interface subsystem;
a data interface subsystem;
a processor subsystem; and
a memory subsystem comprising a non-transitory computer-readable medium that comprises one or more instructions that when executed by the processor subsystem, causes the processor subsystem to:
capture sensor data comprising a first exposure and a second exposure via the dual readout camera sensor;
convert the first exposure of the sensor data to first numeric tuples of a linear color space and the second exposure of the sensor data to second numeric tuples of the linear color space, the linear color space characterized by preservation of arithmetic properties of addition and scalability of the first numeric tuples and the second numeric tuples;
composite the first numeric tuples and the second numeric tuples to composited numeric tuples;
compress the composited numeric tuples to a transport color space based on at least one hardware parameter, the transport color space comprising a log-based color space different from the linear color space; and
encode the composited numeric tuples for transfer to a sink device.
