This is not true. "The main drawback of active shutters is that most 3D videos and movies were shot with simultaneous left and right views, so that it introduces a "time parallax" for anything side-moving: for instance, someone walking at 3.4 mph will be seen 20% too close or 25% too remote in the most current case of a 2x60 Hz projection." If the left and right images were taken sequentially then there would be a time parallax. The object will be in a different place when left image is taken that it is when the right image is taken so the eye sees this left right difference as further or closer than it should be. But when the images are taken simultaneously there is no "time parallax". The images are of the same moment. Even though the eyes see them alternately persistence of vision makes them appear simultaneous.If the cameras are not synchronized to be simultaneous and the object is moving fast enough there will be time parallax regardless of the presentation method, active shutter glass or passive anaglyph. 98.164.64.98 (talk) 10:52, 22 February 2019 (UTC)
Sorry, but that image of the Passiflora caerulea flowers is a very bad example, because each side has two flowers, plus they're very similar, plus they are spread far apart. I never could see it! I'm guessing many people freeview as I do: let the eyes float and then try to look at one prominent point, which is tough when there are four flowers swimming around. This image would be good as a difficult challenge, like a tongue twister. Lovely image, though-- you could just crop it to one flower.

Stereoscopy is a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision. This image of two Passiflora caerulea flowers is arranged as a stereo image pair; it can be viewed stereoscopically by using the cross-eyed viewing method (parallel version here).
Might it be worth mentioning somewhere that Dr Brian May, the guitarist of Queen, is a collector of stereoscopic images and equipment. He has a website dedicated solely to stereoscopy: https://www.londonstereo.com/ 81.131.173.194 (talk) 13:08, 1 November 2021 (UTC)
