This is a diptych in the sense that there are indeed two seperate scenes exposed, but this is an in-camera double exposure, a pic of a window and one of some paintings (had to gallery-sit again today). The alignment of the window frames over the paintings was pure luck. Used a Silver Efex Pro filter to convert to b&w, then added my old film overlay here
Good work, I especially like how the two paintings seem to relate to each other.
I took my first in-camera double exposures just recently. I know "everything" can be done in PP, but there's something interesting about working this way, too.
