I'm not sure which of the following is correct because I've seen both used in the same context:
I look up from his body to Sarah.
I look up from his body at Sarah.
If I take the 'from his body' away and analyse the sentence without it, I would say the right answer would be, I look up at Sarah. If I say I look up to Sarah, it alters the meaning.
However, since my searching has revealed both uses, I don't trust my instincts.
Which is right?
