I've not found 2400 dpi to be worth it. It would be usefull for printing but not viewing. Films Film is a chemical marvel.
Film is exceedingly sensitive once it has been exposed to light.
You should process the film as quickly as possible and keep it cool. Different film speeds and different film formulations have different sensitivies to light. UV light tends to wash out film and special films are sensitive in the infrared spectrum. Slide, or positive, film expands the contrast of pictures. As a result it is much more sensitive to the exposure settings and is unable to capture a wide contast range.
