Actually, we probably have more than one building that resembles a castle in Winnipeg. This one (the one on your right) we stayed at when we were first married. There were rumours of rooms being haunted but we didn't encounter any ghosts on our honeymoon!
I used settings f/9 and 1/160 and 100 ISO for this shot. Since I didn't have a tripod, holding the camera steady was important but a little easier with the faster speed.
Once on my computer I used a preset and then also brought it into Photoshop to add a layer to get some great lighting enhancements. I think the end result brings a bit of fantasy and mystery to this shot. Every castle needs a bit of mystery, no?
