A sleeker moi from back in the day....from 1986.
A double exposure in-camera....on slide film.
The first about a 30 second exposure at twilight with me rushing into the shot for the last 10 seconds.
The second exposure was probably an hour or two long, taken during the night while the camera was still on the tripod allowing for the trailing stars. Moonlight provides the greenish hue on the building.
