Image resolution - Wikipedia
35 mm film is scanned for release on DVD at 1080 or 2000 lines as of 2005. The actual resolution of 35 mm camera original negatives is the subject of much debate. Measured resolutions of negative film have ranged from 25–200 LP/mm, which equates to a range of 325 lines for 2-perf, to (theoretically) over 2300 lines for 4-perf shot on T-Max 100.
