Postscript: Another typecast that was photographed using the iPad2's camera, this time with a pair of bright lights illuminating the page as with a copy stand. I used the Simply B+W app to adjust the contrast and brightness, and cropped the border of the image using the iPad's crop feature built into its photo viewer. Uploaded to Flickr via email, the typecast image was then rotated into portrait mode.
As for the lead-in photo, it was taken with the Hipstamatic app, which I'm finding is the best app for getting interesting, moody photos with little or no fuss.
Typed while sitting in bed with the Olivetti on a lap desk. I'm starting to like this work-flow.
