Hi All!
Whilst my scanner only lets me scan my negatives at 50 x 50 mm, it has a resolution of 2400 x 2400 dpi. The same scanner is able to go up to 4800 x 4800 dpi by interpolation. (or is the real term extrapolation?)
When I use fine grain B&W film, Ilford Pan X or Dela 100 for ex&le, the images improve in quality up to the 2400 x 2400 level. After that the images get a bit too large to handle on my computer, and the improvement is less noticeable.
My question is this: If I invest in a scanner able to handle 4800x4800 will the images be any better, or am I reaching the level where the grain of the film will be the limiting factor?
(I've looked through my reference books here, but I haven't found an indication of the size of crystals deposited in film emulsions, and I'm sure that that is not the only factor involved)
OK, we are already at something in the region of 23 mega pixels when scanning at 2400, and at the end of the day the best (and probably the most economical) solution is to produce large prints with an optical enlarger, so as soon as I have built the darkroom in our new house the question becomes somewhat acedemic. But I would be interested to hear of other peoples experiences.
Best regards to all,
Gerard
