Interesting, and good to know.  (Alas, I'm still muddling along in v3.6.1; no
HDR or OpenEXR output.) I should have mentioned that my own frame averaging is
done within POV-Ray (by simply applying the static images to a box for
averaging/re-rendering, using ambient 1.0)

For HDR/OpenEXR averaging or blending, do you use an external image editor like
Photoshop? Or can the averaging be done in POV-Ray like I do (using the
appropriate beta version, of course) and still retain those highlights and
dynamic range? I.e., has the *average* pattern in POV-Ray been changed as well,
to retain the higher dynamic range of such averaged images?
