I made a day trip to Simon's Cameras yesterday to find a tripod part - and thus found myself in Old Montreal. The day was windy and brisk, with fast-moving clouds allowing a low-angled afternoon sun to peek through occasionally. I walked from the City Hall down Rue St. Vincent towards the St. Lawrence River then west on Rue St. Paul, snapping randomly. These nine uncropped images were given the antique treatment using the 'Sepia' setting in Adobe Lightroom as a starting point. I fiddled generously with the individual sliders after that.
