Scanning in some old photos for my mum after a long struggle trying to get my old scanner to work with OS X.
TWAIN SANE is smashing, unlike the Canon drivers, which won't even install on my machine. Why are hardware manufacturers universally rubbish at writing software? It's the same with Canon cameras, which I love, the bundled programs are dreadful, but are the only thing available for doing fun stuff like time-lapse, or useful stuff like lens distortion correction on RAW files.
Found the info I needed here, incidentally.
