Oh, cool, they're still in business, and workin' the digital age...

I bought an Expodisc years ago to be able to do incident readings using
a (film) camera's in-camera meter.  It kind of fell out of use, because
it was quicker to just do reflected readings or use an actual separate
hand-held meter for incident readings...  but adding the dimension of
color for digitalia, the device seems newly brilliant.
