For all of the advantages of digital over film, it seems that 35mm film still holds a resolution advantage over this year's high-end digital cameras. But clearly digital is catching up fast. I'm curious what folks think is a reasonable digital equivalent resolution for 35mm film. Since this depends on the type of film, let's consider a fine grain slide film, say Fuji Velvia, as a benchmark. With this film, my Nikon Coolscan 4000 scans roughly 3500x5100 pixels at a bit depth of 14 and I'd say the film still has more data that hasn't been captured by the scanner (i.e. the grain still appears smaller than a scanned pixel). Is 14 bits enough to capture the tonal range of this film? It doesn't look like this next year's digital cameras will quite get to the resolution of this film, but in 2004 they almost certainly will.
Then it's onwards to the resolution of medium format cameras
