The MTA's webage on the Q Service doesn't answer the question.
The Wikipedia article on the Q line, however, says the Q service crosses the East River on tracks which lie on the south side of the Manhattan Bridge. Here's a screenshot from that page:
Since the two bridges are less than a half-mile apart, you should have a good view.

As of July 2019, the (Q) Broadway Express - Brighton Local runs from 96 St - Av on the IND 2nd Av Line down the BMT Broadway Express tracks, across the Manhattan Bridge (south side, facing Brooklyn Bridge), and down the BMT Brighton Beach Line to Coney Island - Stillwell Avenue.
It runs on the Manhattan Bridge at all times, including late nights and weekends. The only times the (Q) runs via the Montague Street Tunnel (B'way/Nassau-4 Av Local tracks) are during reroutes where the bridge is closed.
As mentioned in a prior answer, the official NYC Subway Map notes that the (Q) runs via the Manhattan Bridge. The tracks on the north side of the Manhattan Bridge are used by the 6 Av Express via Chrystie and are not currently used by the (Q).
