'Absolutely spectacular': Artemis II crew see first glimpse of far side of Moon

Astronauts on the Artemis II mission are on the third day of their journey around the far side of the Moon.

I am curious. If it is on the far side, where does the light come from for the photos? Other stars?
The sun still. It's just that that side never points towards the earth, but it still gets sunlight. Same as how the side we see isn't fully lit except during a full moon.
