Film versus Digital Resolution

Here is an interesting diagram by ClarkVision which depicts his research on the correlation in mega pixels between the different 35mm films at variable ISO levels.

He says:

"While my research is preliminary, it does seem to agree with what people are saying, and because people look at different things (image smoothness versus spatial detail), it shows there is a lot of room for interpretation."



It is the second diagram (see below) that's really interesting as he tries to correlate film resolution against the different DSLR on the market. Based on his diagram, the sensors in some DSLR camera, notably the Canon 1Ds mark II have already exceeded the resolution in film.
