Is it true 4k scan does not do much for 16mm compared to 2K scan? in Grading, DI and Telecine Posted July 19 Great answers here. Most important is maxing out what 16mm can do for you by using sharp lenses and proper focus & exposure and using the slowest film stock you can for the project. 4k scans will almost always be an improvement, how much of an improvement will be based on how well it's shot. If the image doesn't hit the film sharp and clear, higher resolution scans will only give marginal improvements and may not be worth the cost. When it's shot well, 4k absolutely improves the final result even when finishing in HD. Plus you can reframe a little bit if needed which is nice.
