As part of the process of exploring what my Epson V500 scanner could do at high resolution I decided to revisit some old black and white negatives and re-scan at 6,000 dpi.
This is a little bit full-on in your face, so first some overviews –
(left) the V500 high-resolution negative scan side by side with one I did a couple of years ago from a print (right).
I used an evaluation copy of Vuescan (hence the $ watermarks here) to produce a raw image some 6000 x 9000 pixels; after adjustments and croppings this reduced to 5601 x 8326 px, or ~46 MP.
Below is a 2400 pixel version – about 1/10 the number of pixels – which still shows quite remarkable detail. The lettering on the face of the clock of the Lutine Bell is quite clear, and the faces of some of the people looking down from a few floors up will probably be recognisable to people that know them.
The source DNG file on my hard drive is 105 MB so I won’t be doing this too often …
