A photo used to be a photo, a video a video. In 2025 they are data sets!

Back in the day, a photo used to be a negative or print, a video would be an 8mm film or perhaps VHS tape - and then the digital age was upon us, with the advent, especially, of phones with cameras. Starting with, arguably the Nokia N93, in 2006, we had useable, focussed, 3MP photos, and useable 'DVD quality' video files - captured from a phone. A photo was, typically, a .JPG file and a video was, typically, a .MP4 file (I won't get into codecs here, to keep things simple). Each - literally - just a file. And then manufacturers started adding on information. Some of which could be contained within the original files, but mostly... not. Starting with Nokia's experiments with 'live' photos on their Lumia phones around 2012, where a small section of video (from before the shutter was pressed and after) was captured and stored with the JPG photo. Then, with the core of Nokia's imaging team being made redundant and moving to Apple, we had live photos making a wel...

Say you want to use a section of the photo only, cropping in to a group of people or an object in a scene. Or you want to show the photo on a large desktop display or TV. Good luck with that with a photo grabbed at 12MP on an iPhone or Pixel or Samsung flagship with all default settings. You'll see artefacts, jagged borders where there should be none, and general 'over-processing'. Which is why I applauded Nokia's 'PureView' approach ten yea...
