I suspect this message may be best directed towards Ralph W. Lambrecht. Reading through the calibrating chapter in 'Way Beyond Monochrome' I noticed the suggested filtration values given for a Durst max. 130 unit enlarger are not symmetrical across yellow and magenta. i.e. the step progressions between each value are not numerically equivalent; is this correct, and how variable are these values relatively across different manufacturers of enlargers? For my DeVere 5108 model I applied a multiplication factor of 1.54, i.e. 130 becomes 200.2 units as the filtration values go upto '200'.Tom= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = ====================================================================== To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
