Actually 200 lines/mm - that would be about 5080 dpi, which would impressive for a modern day scanner as well.

- 4ad 8y agoWhat most people don't realise is that can make film that can record at whatever resolution we need, and we have known how to do this for over a century. It's simply a tradeoff between grain size and sensitivity. For most consumer film sensitivity is usually the more favorable trait. But for special applications we might value smaller grain size. For holographic film we can make it record better than 10000 lines/mm. This is essential because we are recording diffraction patterns.
