... or would it. What is the ambient light level in the Huygens Titan pics
comparable with?

If there were no clouds, the surface of Titan would appear about as bright as
the Earth on a stormy day. I'm not sure how much light is fully absorbed by the
atmosphere, but I'd guess that it's still quite a bit brighter than a full Moon
on Earth (which is a darn sight brighter than Tucson at midnight!)
