Ok -- I'm trying to figure out digital resolution for 'decent' 35mm. Lets
assume each pixel is high fidelity. A good film/lens combo gives you 50 lpm
(you might be able to get 100 -- but 50 is pretty good for every day usage).

You need two rows per 'lpm' so 100*35*24*100 = 8400000 or 8 meg pixel (around
24 meg bytes). According to these calculations an 8meg pixel camera should be
on par with typical high (but not optimal) 35mm system. I thought the number
was much higher -- what is wrong with my calculations ?
