Subject: I'm curious as to the light levels around the 4 gas giants.

This is a question which has puzzled me for some time. I'm curious as to 
the light levels around the 4 gas giants, Jupiter, Saturn, Uranus & 
Neptune. I have seen a lot of Voyager photos of these planets, but can't 
help wondering how the planets would appear to the naked eye to an 
observer in the vicinity. I'm aware that Voyager had to take longer and 
longer exposures as it distanced itself from the Sun, and so what appears 
to be a 'bright' Neptune image would have been a lot darker to the naked 
eye.

Put it simply, I'm curious as to just how much I would see if I was a 
human observer in orbit around each of the 4 planets.

Sorry for not phrasing this too well!
