imortant is that 30 km/s my camera see near 15 % different brightness
that is because the light wave is entering your camera
at a higher intensity due to the cameras velocity.
as in the below image , the red light wave @ 680 nm would appear to increase in intensity
( decreasing wavelength )
with camera velocity if the camera were moving toward the light source , by increasing camera velocity the red light would appear to transition from 680 nm to 550 nm and to 410 nm and it would even appear to transition beyond the visible light spectrum if enough velocity is added to the camera in the direction of the red light source.
ie..the camera would no longer see the red light because
as the light waves enter the camera the waves are beyond the
visible light spectrum.
your camera would then need to be able to capture
ultra violet light , x ray light , gamma ray light, and beyond.
