At the risk of incurring the rath of many, it seems logical to me, that if one is comparing film to digital prints, that the film print would be made from the original, not a scan. A wet print compared with a digital print.
Comapring a digital camera file to a scanned film film doesn't seem relavent to me. I cannot see a digital film. I can see a digital print and a film print.
As a complete asside. I have seen that I get better prnts from wet chromes if I first make a color interneg and then print the negative. Any explanation?
Turning to the real world of what people do - and there is no wrath necessary - those who use film but wish to make inkjet prints from film originals will scan the film using a film scanner and then print the digital file which is created by the scanner and scanner software - whether it is negative film, black and white, colour, or positive transparency film. Programs such as Silverfast can handle all of this, and good film scanners can achieve 5400 INPUT PPI or more. A good print resolution is say 360 PPI, so this would allow the large dimension of the print from a 5400 PPI scan to be 15 inches. Good scanning technique of course is required to optimize the quality of the digital file, which means understanding the software and the various adjustments and options it provides for optimizing scan quality. Thereafter it is just a matter of the usual techniques used to derive a good inkjet print from a digital image file. Starting the process by scanning a wet darkroom print is hopelessly inadequate because the resolution of these prints seldom exceeds 200~250 PPI, so you can never get beyond that; as well when you start with film you have all the sharpness and dynamic range of the film, which is far better than anything on paper from a wet darkroom that could be fed into a flatbed scanner.
If you want to make serious comparisons between wet darkroom technology and digital technology, you need to use the techniques that are best adapted to each medium from start to finish, and normalize as many of the variables as possible (very difficult) and see which provides superior quality. While that argument is essentially over with, no harm curious minds trying - but do it in a way that allows each medium to be at its best.
