In the second deep super of each hive is where you can really see a difference. The white HSC frames are quickly filling with bees while the foundation frames are just getting started, with few bees working in the upper deep. You can clearly see the difference in the population of bees on top of the frames in the upper deeps.
The foundation hive is just getting started in that upper deep. You can see here they are just getting comb drawn on one of the center frames (they work from the center frames out to the end frames). See how the bottom center of the foundation is raised to the edge of the frame while the "hill" of comb gradually slopes down leaving the rest of the foundation recessed in the frame.
We'll take a closer look at the frames of both hives in the next week or so.
