This is an actual stereograph, not an artificial 3D conversion made from a single 2D image. The 5-minute 3.7-second interval between two JunoCam images taken during the time lapse sequence of Perijove 17 (21 December 2018 at 17:42:53.876 and 17:47:57.590 UTC) established a stereo base (camera separation) of thousands of kilometers, from which this stereographic image pair was crafted using Photoshop. Thanks to the velocity of Juno, the distance traveled during the interval between these two captures effectively gives our eyes that same separation. Viewing Jupiter at a known average altitude of 59,911.35 km (37,227.1 miles), it's nevertheless possible to perceive features of the atmosphere three dimensionally. Juno's actual speed and, thus, the stereo base for this image pair from Perijove 17, is unknown (at least to the creator of this stereograph). Note that during the 5-minute 3.7-second interval, Juno ascended 8,780.3 km (5,455.8 miles), from 55,521.2 km to 64,301.5 km (a 15.8% gain in altitude), requiring z-axis correction in addition to x- and y-axis skewing, to produce the stereograph.
