Orion over Peace Bridge (24mm D750).jpg
Orion on a clear winter night in downtown Calgary and shining over the pedestrian Peace Bridge over the Bow River. I shot this on January 20, 2018.
This is a real scene, though the sky is a single longer exposure of 6 seconds at ISO 400, while the ground is a blend of 4 exposures from 1.6 to 8 seconds at ISO 100, all at f/2.8 with the 24mm Sigma Art lens and Nikon D750. A NISI Natural Night filter helped cut through light pollution and provide a more natural blue sky, though this was a moonless night. The ground images were blended with luminosity masks generated with ADP Pro v3, to prevent the lights on the bridge from blowing out too much.
Star diffraction spikes added with Astronomy Tools actions.
