This is a photograph of Union Station in Denver CO. It was originally built in the late 1800s and was remodeled along side with the expansion to Denver's transit network. Has a food hall, bar and hotel. This was not commissioned work, just for fun. It is a composite of 4 photos, two bracketed exposures for the building exterior, one for the building lights and finally one for the sky. The streets were not closed down so grabbed a tripod got a bunch of exposures and ran out of the way before the next car came along.
Canon 5dmk4 24mm TSE lens. F16 ISO 100 and varying shutter speeds.
