I experimented with midjourney and while it produced some interesting pieces I couldn't imagine creating something like these tron images with it. Like I couldn't get midjourney to even create a proper looking chess piece for instance
Having read the responses of the guy that generated these, the prompt is as simple as
production still from 1976 of Jodorowsky's TRON, 20 ASA 35mm --v 4 --ar 3:2
production still in version 4 doing most of the heavy lifting, with the year and film propeties giving a bit more vibe, and of course the overarching theme of TRON in the style of Jodorowsky. Add some extra words to differentiate scenes, such as light cycle or disc or computer. Add wide aspect ratio, and that's it. So it's 99% Midjourney. Mind blowing.
I was about to say 'I can't tell if this is AI generated or not at this point' mostly as a joke based on first impressions, but it's actually shocking that it turns out to be.
Version 4 of Midjourney, released 2-3 weeks ago, is an outrageous improvement over all previous versions of Midjourney, and has gone mostly unnoticed by HN. IMO, v4 Midjourney is to DALLE2 what DALLE2 was to all previous AI art generation.
