I've seen the original in person many years ago during a big Magritte exhibit in Montreal, and it's detailed as far as night paintings go. It took me a while actually to register the dissonance between night and day.

I think it's brilliant, because it relies on the twofold meaning of a dark tree: either seen from night, or as underexposed shadow of a contre-jour. In that sense, I think it owes a little bit to photography (our own eyes would see more details) but at the same time is gently mocking it by showing the impossible.
