a. In the photo you see her with Dave standing on a rock.
b. In the photo you see her, with Dave standing on a rock.
c. In the photo you see her, with Dave, standing on a rock.
In which of the above sentences is each of these conclusions correct:
1.She is standing on a rock.
2.Dave is standing on a rock.
3.They are both standing on a rock.
The comma breaks up the association with "her" and "Dave", or it breaks up the association with who is standing on the rock. So:
a. In the photo you see her with Dave standing on a rock.
Because there are no commas, it implies that both of them are standing on the rock.
b. In the photo you see her, with Dave standing on a rock.
Because there is that single comma, it is saying that the photo shows her. It also shows Dave standing on a rock. The implication is that she is not standing on a rock - but she may be.
c. In the photo you see her, with Dave, standing on a rock.
This again implies that you see her and Dave together, and they're both standing on a rock.
