I have no way of determining the facts of the matter relative to the lighting of the Flag from that Photo .
I dont know if this is a before or after photo...or where any lighting might have been installed as said Light Fixures doesnt "fall" within the parameters of the photographic frame, nor would they necessarily have to.
II would think that this Flag would be Illuminated by a fixture or fixtures mounted On or Under the Eaves of her balconey.
As we cant see much OF those
eaves in this photo determining what lighting Exists would be next to impossible
