If the window is on the ground floor, the blind should be closed slats up. Otherwise, people can see in from the floors above. If, however, you are on an upper floor and the slats are up, anyone can see in from the ground floor. For that reason blinds on an upper floor should close slats down.
No, people outside would not be able to see anything of inside, not even movement close to the window, nor the shapes and outlines of things. They would, however, be able to see a diffuse glow of light if you have a reasonably bright light not too far from the window.
More privacy: by turning the blinds up, you limit the amount of visibility space directed towards the room. People won't be able to see inside when passing by.

SCREEN ROLLER BLINDS FOR AMBIENT LIGHT
