Just how much light is available? Are these pictures taken with natural available light, (the light spectrum that we see) or another wavelength?

I was wondering that too...

It seems awful bright for a place that far away from the sun, on the other hand, it's getting both direct sunlight and the sunlight reflected off saturn...

IR

DISR
DISR (Descent Imager and Spectral Radiometer) is an optical remote sensing instrument. It includes a set of upward and downward looking photometers, visible and infrared spectrometers, a solar aureole sensor, a side-looking imager, and two down-looking imagers - one providing medium resolution and the other high resolution. There is also a sun sensor that will measure the spin rate of the probe. DISR will make measurements in the 0.3 to 1.7 µm range.


DISR Measurements

Upward and downward looking photometer
Violet light

Spectrometers
Visible (480 - 960 nm)
Infrared (0.87 - 1 µm)

Downward and side-looking imagers 0.66 - 1 µm
Solar aureole photometer 550 nm, 939 nm
