About the location
Brussels is located in the centre of the country and has, from the perspective of a photographer, much more to offer than you might think. A lot of beautiful architecture like the palace or the Belgian Arc de Triomphe at Jubepark (Fr.: Parc du Cinquantenaire).
Another great reason to visit Brussels during spring is obviously the amazing woods of Hallerbos, which are only around 17 km away from the city. They are no hidden gem anymore though, so the best time to visit this place is during the week in the early morning.
