As can be seen in the screenshot there is a large area in the middle of the screen that is unused .
I have not been able to reclaim that space by resizing the columns: instead the details panel seems to have a fixed proprtion of the Finder window horizontal width. Here is what clicking in the "dead space" does:
I have been using Finder multiple hours in the past two days to view images . I have killed it (via Activity Monitor) multiple times and even rebooted the machine: nothing changes the behavior.
Am I missing some setting/ knob to reclaim that space?

There should be two ways to reclaim 'dead space':
drag column width (works only on separator between 'Name' and column next to it; 'Name' column width 'consumes' dead space width)
drag Finder window size (right side) smaller (size reduction starts at expense of 'dead space')
In both cases in order to work pointer must turn into "arrow left and right" (↔)
