Dear Terence Eden.
The Beinecke Library electronic collection graphics files used to have a resolution of 400 dpi.
Now the resolution has decreased and it has become impossible to read the details.
The manuscript was photographed with a Phase One IQ180 camera, which has a resolution of 10380 x 7816 or 80 megapixels.
Could you please give me a link to manuscript files at 1200 dpi or higher?
Respectfully, Mark.
