Re: [Digital BW] Re: Native resolution for scanning

Austin,

I shall treasure that reply and put it in a folder of its own headed "What
Austin doesn't know"!

I'm not quite sure how we got into this discussion on the B&W list (I had to
look twice to see what list we were on), but since we've started we might as
well finish:

The line I quoted is in the Product Specifications (and copied below):

      CCD 6 line alternated with 61,200 pixels CCD



61K pixels over 6 lines gives 10200 per line, which over an 8" scanning
width gives just over 1200 pixels per inch.

I seem to remember an earlier fuss because Epson was using staggered lines
of sensors and claiming higher resolution (just as Fuji do with the S1?).

It will be interesting to see what you find out.

Bob Frost.
