Once the scan happens, you get a file. Not a .jpg. Not a .mp4. You get a DPX sequence or an EXR file.

A 90-minute IMAX feature scanned at 8K generates roughly 40 to 50 Terabytes of data. That is the entire digital archive of a small university on one hard drive. imax film scan

These files are "flat" (Log color space). They look gray, washed out, and terrifying. But that flatness contains the full dynamic range of the film stock—as much contrast as the human eye can see in a theater. Once the scan happens, you get a file

Let’s pull back the curtain on how 15-perf 70mm film makes the jump from celluloid to terabyte.
