How bright is it on Pluto in the middle of the day? I just saw a documentary about New Horizons and Pluto with plenty of photos New Horizon had taken of Pluto. All these photos were very bright, like Earth would be during the day. Considering the distance between Pluto and the sun I suspect the brightness of the photos has been manipulated.
So, if you would be standing on Pluto's equator when the sun is in zenit, how bright would it be?
Back when New Horizons was preparing for its flyby back int 2015, NASA's website set up a tool to allow you to experience the brightness of light at High Noon on the subsolar point on Pluto.

To an observer on Pluto's surface, the sun would be about 1,000 times
dimmer than it is here on Earth, NASA officials said. At noon, the
sunlight would be strong enough for you to read a book, they added.
(Though it might be hard to keep your eyes from straying upward to
take in the exotic Pluto sky, with the big moon Charon looming just
overhead.)

In general, the time it will return for you will be a little bit after sunset (or before sunrise), but still bright enough for pretty good vision. For my current location, at about 41° N latitude , on October 31, 2020, it's giving me a local time of five minutes after sunset.
