Peter film is all grain that’s how it is made up rather than pixels or dots.
And yes if you enlarge film you enlarge grain. But at the image sizes you are talking about toy should not be seeing the grain unless it’s a very fast film. The slower the film the finer the grain.
The grain on film rarely bothers the audience at the cinema (a much larger image than most on here will ever need) because professional directors of photography know how to handle the image and use the grain to best advantage.
But it is not just a matter of image resolution it is also the range of colours that can be resolved. By comparison most digital equipment resolve colour like a set of Pantone.sheets rather than a paint box of mixed colour.
Just go and look at a 8k scanner such as can be found at Lucas Film.
Finally it is the acceptance of the human eye. It is not for nothing that most digital software has a film look filter.
I stick to my opinion that there are very few digital cameras on the market that can have the resolution of 35mm film.
And even less with the resolving power of a 2.25 square camera such as the old Rollieflex, let alone a Hasseblad or Bronica.
Just go to an IMAX or Omnimax Cinema.
Try projecting an IMAX image with a digital projector without LCD goggles.
What do you mean by imaging accuracy?
Are you talking of the difference between and art and a photocopy? Photography IMHO is as much as an art as it is a technology. Top photographers and cinematographers create images that don’t just use the technology to copy what’s in front of them. For your happy snaps you don’t need any special gear a smartphone and jpegs will do great for that with the added advantage that you will probably have the phone with you when a photo opportunity presents itself.
Then Adobe’s lightroom and photoshop are also a bit over the top. Free software will do the job just as well if you know how to use it.
Movie and still are completely different things. The brain perceives them very differently. One should not mix up the two.
Peter movies are simply a set of still images and viewed by the human brain through persistance of vision.
Many scenes such as on The Matrix were actually shot with a number of still cameras laid out in such a way that when you put a still from each of the cameras one after another you get a moving image making the special effect movements.
The main difference is the way in which stills and moving images are exhibited.
Digital technology has in fact returned to the mix of moving images from a series of stills that used to be used in the early days of the moving image where a cameraman used to turn a handle to bring each frame in front of the lens as one would with a still image.
