Especially when you think about the mp equivalent of the resolution of film

Quote:
The Digital Resolution of Film
So how many pixels does it take to describe all the detail we can get from film?
Fuji Velvia 50 is rated to resolve 160 lines per millimeter. This is the finest level of detail it can resolve, at which point its MTF just about hits zero.
Each line will require one light and one dark pixel, or two pixels. Thus it will take about 320 pixels per millimeter to represent what's on Velvia 50.
320 pixels x 320 pixels is 0.1MP per square millimeter.
35mm film is 24 x 36mm, or 864 square millimeters.
To scan most of the detail on a 35mm photo, you'll need about 864 x 0.1, or 87 Megapixels.
But wait: each film pixel represents true R, G and B data, not the softer Bayer interpolated data from digital camera sensors. A single-chip 87 MP digital camera still couldn't see details as fine as a piece of 35mm film.
Since the lie factor factor from digital cameras is about two, you'd need a digital camera of about 87 x 2 = 175 MP to see every last detail that makes onto film.
That's just 35mm film. Pros don't shoot 35mm, they usually shoot 2-1/4" or 4x5."
At the same rates, 2-1/4" (56mm square) would be 313 MP, and 4x5" (95x120mm) would be 95 x 120 = 11,400 square millimeters = 1,140 MP, with no Bayer Interpolation. A digital camera with Bayer Interpolation would need to be rated at better than 2 gigapixels to see things that can be seen on a sheet of 4x5" film.

I'm reading different things on different sites. Warning: may not be accurate (referring to the quoted "digital revolution of film".)

IME I've found it to be true. Of course it depends on how the image is finally output. If it's totally an analog procedure this will hold true every time. If it is ever converted to digital then the final image will only be as good as the equipment it is scanned on. I've had folks take different films and digital shots then put them on the photo forum and say "See, the quality is still there". Problem is as soon as they scanned it you've lost any viable comparison.

It's not just digitizing it though. When we print them offset you can only get detail to a certain point depending on the LPI of your halftone screens.
