I have been doing commissioned light paintings for the past dozen years, but this was by far the most complicated. A Godox LC500 light wand was fastened to a painter's pole and exposed small areas of the building at a time, along with the foreground rocks and foliage. A light attached to a drone lit the higher floors and the roof. Lights were turned on in the home and different exposures were made to ensure the lighting was even.
In all, 36 separate images were made at various long exposures and blended in Photoshop. The camera was a Hasselblad H6D-100c with a 28mm lens at f/22 and ISO 100.
