Slide film has about an 8 stop dynamic range depending on the particular film. This is very similar to what we see with digital cameras although some may have a wider dynamic range. With color negative film this can be as much as 20 stops and most are at least 15 stops. This is a distinct advantage when shooting panos that have things like the sun and deep shadows in the same scene. In other words by default negative film is an HDR medium if it is used correctly (IE. expose for the shadows). On the other hand slide film generally has a better (IE. finer) grain structure and as a result tends to have better detail if the cameras glass is good enough. But for me the real bummer with slide film is that Kodachrome is no longer available and the last place that processed it just closed down a few months ago. > > > To put it the other way round: is there a reason why you would prefer > > slide film over negs if we put away all digital cameras for a moment? > > ... and that the difference was made by the output "medium" (paper vs. > light). > > My reason to prefer slides over negatives for my silver-based photography > back in the time was the size and vibrance of a projection compared with > the small size, environmental impact, and relatively less vibrant sight of > a printed negative.
