I was down at the local pro lab today and saw a new sign in the window that
said they have a 8000dpi drum scanner.

I finally sat down this evening and did some math using film specifications in line pairs per millimeter and looking at their MTF curves. From what I was able to determine, 8000 dpi is centered at about the limit of film information content in pixels. Some films have a little more and other films have a little less. Films such as Tech Pan have much, much more content.

Then there's the analog color information color films contain . . .
