(thanks to Alex for the use of his face.)
I’ve posted an applet of my Processing-made slit-scanning self-portrait program, called SlitScanMan. (click on the name to go there.) Hope it works for you… just trust the certificate when it asks (er you do trust me, right?) It’s supposed to use your webcam (or whatever photographic input device was used last.) Instructions follow:
Press 1 for default mode – click and drag a rectangle, and that will be updated on mouse up.
2 – click and drag, but with “live update” as you change the box.
3 – horizontal scan.
4 – vertical scan.
5 – freeze.
t – (if you run the code on your machine instead of online) takes a tiff of the picture and saves it to disk.
