Hmmm.. I reckon that a good 35mm camera (good meaning a top-end lens and 
fine grain film) is equivalent to 12-20 megapixels. Rmemeber there is a 
big differnce between 'sharpness' (which can be fiddled later with a 
digital camera) and resolution (i.e. the ability to see fine detail in 
the image).

Large format film is between 0.5 to 1 _gigapixel_ IMHO.

True, but that's no reason not to record them in the first place. You can 
always loose information (e.g. by scanning at a lower resolution), you 
can never gain it. 

In other words, if I take a large-format film picture of something, I can 
always scan the negative or a print made from it and, say, produce an 
8Mpixel image (which would be considerably poorer than the original film 
image). But if you take an 8Mpixel image with a digital camera, no way 
can you then produce something equivalent to my film.
