I have a wonderful row of north facing windows that are directly across from a building with south facing windows. Every morning the sun shines on those south facing windows and reflects directly into my windows. I know, obviously that this light is not "direct" light because the sun is not shining directly into my apartment.
I also know that if I leave a photograph in the path of this light, it might fade. Am I incorrect in this assumption? Is the light any less intense because it is reflected OR is it more intense because of that reflection?

What is the truth here, with the light?

It could be either, depending on the configuration of the windows. There is a building in England famous for melting plastic in parked cars. Slap an UV blocking layer of plastic on your window and 70% or more of any problem with fading will go away.

Normally, I'd say that reflected light has less intensity than the original light source, but Harry has a point about the configuration of the windows. If the windows facing you form a concave reflective surface, then they'd concentrate the light like a magnifying glass does.

If you really want to know, try leaving a photograph in the path of this light to see if it might fade - but use a photo that you don't care about.

A space blanket can be used to tint top part of the window to reflect light back at those no good neighbors.
