And one can depict certain kinds of scientific labor with some success. Films about painters can be spectacular, as they go about recreating every stage of a famous painting's evolution, from the first penciled line to the final brush stroke.

Their work is hopelessly un-photogenic.
Someone sits at a table or lies on a sofa while staring motionless at a wall or ceiling.
I've mentioned inspiration. Contemporary poets answer evasively when asked what it is, and if it actually exists. It's not that they've never known the blessing of this inner impulse. It's just not easy to explain something to someone else that you don't understand yourself. When I'm asked about this on occasion, I hedge the question too.
