Looks like densitometers are close to $1k (B&H).  Does it make any
sense to use a flatbed scanner like the Epson 3200 as a 
densitometer ?   In other words, print out your grayscale step wedge,
then scan it in and look at the grayscale values in Photoshop ?

Or does the non-linearity of the scanner make it simply the
moral equivalent of chasing your tail ?  But it seems like with
a standard grayscale, one could linearize the scanner.

Just a thought, John
