Once we have photographed a location in the traditional manner, we are always looking for a "new view" and reflections are one of our favorite approaches. We normally work with as maximum depth of field as possible, because sometimes the reflection can be quite deep into the glass. Using or not using a polarizer is something we always test out. We love to frame our images and to be able to frame with a reflection is a double whammy. It is also a testimonial to revisiting a place many times; as the light changes, and as your vision changes, new images and new challenges always arise.
