Understandably, there was scepticism around this claim, especially because the film looks so studied and mature. But as more details emerge, it turns out that Jonny Mass really is a prodigiously gifted filmmaker, and that the Weapon camera fitted with the new sensor is a staggeringly good device.
Almost right up to this point, the phrase "working with 8K" has been synonymous with "that's almost impossible". And yet, if a 19-year old — admittedly with a lot of help, of course — can make an 8K film in 24 hours, something massive has changed.
And what has changed is that there's shortly going to be a commercially available 8K camera at a realistic cost (i.e. realistic to buy for many filmmakers) and that workflows exist to edit and post produce efficiently, without a ton of experimental or kludged-together gear.
So, how was this done? How was it shot in 24 hours, and post produced in 8K, complete with a comprehensive colour grade that is key to the story line?
The colour work was done with the help of a LUT library from LUTIFY.ME.
LUTIFY has a full and comprehensive interview with Jonny Mass on their website, here. It's a good read!
