I use to hate it when people walk through my architectural shots but I’ve learned to shoot a few frames with people if the opportunity arises. Sometimes the shots look better with people in them even if there is motion blur. This time the third person who walked through that looked great. I was pleasantly surprised to see the touch of red come through on an otherwise drab shot. I was shooting long exposures on a tripod but was able to change my settings quick enough to freeze the action at precisely the right moment. We had to ask her for a model release after and she was so nice that she even offered to walk out again for us.
