Sandy, did you think I would pass up the opportunity to mention that the
Stouffer 21-step, as explained in Post-Factory Photography Issue #1
("Sense & Sensitometry" article), is only $5.40 uncalibrated, while the
Kodak uncalibrated costs lots more & the Kodak calibrated will set you
back about the cost of a battleship? There's also a chart of the readings
on my Macbeth for a 21-step, which might be of use.
