Your timing was immaculate, thanks. This high resolution photo shows no "dust parabola" between the feet - here we see no dust at all, at apex.
Have you not studied this stuff? Can you find the wire that's supposedly suspending John Young? I can only find his aerial, which is shaped like a carpenter's metal measuring tape and, in this case, is reflecting the black lunar sky.
We can see very little dust in both photos because most of it is simply sunlit grey up in the vacuum against the same shade of sunlit grey in the background. What we most need to look for is light-coloured dust against darker background, or dark dust (either shaded or actually darker) against lighter background, and then, by comparing both photos, small amounts of it become visible.
Such as in the small bit of shade on the toes of Young's boots; against the shade of the lunar module to his right (our left); in the shade of the boot print from his right foot in the second photo, AS16-113-18340, which is almost obliterated by dust in 18339; in the shadow of Young's boot(s) on the ground.
Some of the dust has actually been caught in motion at a right angle to the camera's axis as the shutter went off, so is slightly streaked. In other cases it's frozen, or almost frozen. The little bit in AS16-113-18340 against the LM's shadow and surrounding some of the central fiducial (crosshair) might include tiny glass beads which seem to be reflecting circular greenish flares of the sunlight. On the other hand, those same formations might be a simple, rare, film or developing fault which I occasionally experienced back in the 1970s.
Here are the appropriate photo captions in plain text from the Apollo 16 Lunar Surface Journal Image Library. Go to the real thing for all the lovely links. I wonder if the red-blue anaglyphs might show more dust.

120:25:42 John Young jumps off the ground and salutes for this superb tourist picture. He is off the ground about 1.45 seconds which, in the lunar gravity field, means that he launched himself at a velocity of about 1.17 m/s and reached a maximum height of 0.42 m. Although the suit and backpack weigh as much as he does, his total weight is only about 65 pounds (30 kg) and, to get this height, he only had to bend his knees slightly and then push up with his legs. In the background, we can see the UV astronomy camera, the flag, the LM, the Rover with the TV camera watching John, and Stone Mountain. Journal Contributor Joe Cannaday notes that high-point of John's first jump was at a time close to 120:25:49 and the second was almost exactly three seconds later.
AS16-113-18339/40 Stereo Images: red-blue anaglyph and a left-right image pair
These stereo images were created by Yuri Krasilnikov, who writes, "A bit of artistry was necessary to create credible stereo. In the left-right pair, Charlie captured John's first jump in 18339, which is on the right. In the original of 18340, we see that John isn't as far off the ground and is tilted to his left. In addition, there are footprints beneath him that he made when he landed after the first jump, a clear indication that John is closer to Charlie than he was in 18339. Creation of a credible anaglyph required removal of the image of John from 18340 and careful replacement with the image of John from 18339."
Yuri has also made a two-frame animation (1Mb) of John's jumps. John is more upright in 18339; and there are prominent footprints at his second launch point in 18340.
See, also, a red-blue anaglyph (1.9 Mb) created by Erik van Meihgaarden, who writes, "John did two jumping salutes for Charlie, who took a picture each time John was near the top of his jump. Consequently, we are seeing not only from two slightly different view points but, also, when he was at slightly different places. The TV recordings of these jumps show that John was on the LM side of the flag. Combination of images from the two different jumps creates the impression that John is on Charlie's side of the flag. John also looks like he's jumped more than the half meter he actually achieved. In comparison, because the flag wasn't touched or moved between the two jumps, our stereoview of it is completely legitimate.

120:25:42 John's second jump lasts about 1.30 seconds and, consequently, his launch velocity is about 1.05 m/s and his maximum height is 0.34 m.
