yes! Word Painting has a nice section about this too, about a poem that zooms in on a girl trying to buy a button for a coat for her father's funeral -- the author makes the point that the resulting image and observant description says a lot more about grief than any number of words like "pain", "hollow", "grief" would.

I thought about this more, and I think that magic happens as well because -- in contrast to the idea that writing "small" is simplification or reduction and such -- zooming in can in fact be a technique of avoiding that simplification and reduction, of not letting your subject fall prey to homogeneity in writing, if that makes sense.
