👉 Okay, let’s tackle these…

. MPIs! Now, I gotta be upfront here - nobody outside of a very specific corner of the weird and wonderful world of 3D archaeology actually knows what they fully mean. And frankly? Neither did I until I spent a frankly unsettling amount of time squinting at a screen full of 3-megapixel isoscapes.
Basically—and this is the layman's half of it—MPI stands for Mapped Photographic Indices. They are essentially, photographic ghosts. When you scan an archaeological dig site with very high-megapixel rigs (fancy 3D scanners that basically vomit up huge pictures of everything, really densely packed), what you get aren't pretty pretty pictures. You get...noise. A whole lotta random, apparently meaningless speckles and distortions in the image. Initially, archaeologists thought these were just technical glitches – bad scans, dodgy equipment, maybe even a very aggressive house spider messing with things. Turns out… they weren't. 98% of that noise—the MPI! —actually represents faint, almost undetectable traces of what we now think are residual psychic impressions from the past. Think about it: you, sitting there in that dig pit, crammed amongst the trowels and the sweat, would probably pick up a little bit of everything. Trauma, fear, excitement, maybe even really bad cafeteria food that stuck around for centuries. Now, when the scanner’s done, those
