Robert Godwin of Apogee Publishing and Media, speaking as part of a panel at the EAA AirVenture in Oshkosh, Wisconsin, debuted newly-enhanced footage from the Apollo 11 EVA, revealing details previously hidden in the shadows. (The video should start where the segment begins, but if not, skip ahead to 53 minutes, 45 seconds.)

This is great. Even though the Honeysuckle Creek SSTV data tapes were erased and forever lost sometime in the 1980s, a real labor of love still continues today to improve and enhance every source of Apollo 11 EVA film and video that we still have now.

In the video it is explained that the astronauts in the shadow were first detected in an internegative, which is also shown in the video. However, the DAC 16 mm camera used color-reversal film (SO-168 for magazine K), which does not produce a negative, but directly a positive film when developed.
However, the "Apollo 11 Lunar Photography" document (NSSDC ID No 69-059A-01) mentions that the film can be ordered as color positive or negative duplicate.
Is it known whether the enhancement shown is based upon the negative or the positive?

It sure sounds like the internegative was used for the latest HD scan shown last in the video.
Internegative film was typically used to make prints from color positive film before the introduction of scanning. It would have been used to make prints from frames of the 16mm original film, if needed.
What interests me is, the latest NASA HD scan for the Apollo 11 movie could not pull out that same detail. The internegative is a second generation copy.

We did not scan the original 16mm flight film for "Apollo 11," we used a second generation copy (in part because of logistical issues at Johnson Space Center).
Nor did we go looking to raise detail from the shadows because most of our focus (and time) was spent on processing the newly-found 70mm film and 11,000 hours of audio. (If those two new assets hadn't surfaced, then we would have probably spent much time on the 16mm film given that it would have been the only material available.)
We may have been able to achieve the same as Apogee had we done an HDR scan of the flight film.
