It is very dark... in space...

[PvK]

I've looked closer at this.

I can see it fine with gamma set to +2 or so. Nothing in Approaching Infinity really looks too bright with gamma +2, and even the text is slightly easier to read, for me.

However with normal gamma in a lit room, most things are actually ok. The things I know but are out of immediate sight are dim but visible. What is not visible, and almost impossible to distinguish, are the fog of war blues - both the blue grid showing "unknown" and the opaque solid blue for "once seen but not now" are both almost impossible for me to tell from the black of "space that's in view". So just brightening those two blue images might do it for me just as well.
