Similar movie with young african american girl as the kid?

There was another movie from aorund the same time which featured a young black girl who goes back in time to england, and I remember the antagonist was some evil b*tch, maybe a queen.

I remember the girl was accused of sorcery, when she took a Polaroid picture of someone, and there was something significant about knowing when a solar eclipse would take place

does anyone remember what this was called?
