I love situations like this where the light indeed wanders as the day goes on. And as the year goes on it changes location, too. Film grain does suit it.
Such a neat entryway! Love the porthole. This shot screams to have lots of black and white high contrast...the grain is good too. Looks like something sort of Hitchcock-ish to me.
Hmmmm. I think I might have pulled back on the grain a tad, but it's an interesting composition, and I really like that round shadow. Might be fun to try this ini B&W.
I like the theme you have with the 3 objects. My first thought when I looked at this was 'why is there so much noise when there is that much light'. Now I know! Question: why isn't the grain apparent over the bright areas?
