It appears Kodachrome isn't as good as it used to be. I guess nothing is sacred anymore:-(. Bud Cook - ------------------------------------------------------------------------- Kodak is putting Kodachrome 25, 64, and 200 under the "Select Series" label. Their updated technical data publication (Jan.98, E88)has RMS values of 11, 12, and 19 respectively (the old values were 9, 10, and 16). Kodak was quite responsive and provided the following explanation: <snip> - - there have been subtle changes to the film (from mfg changes) over the years that have slightly increased grain size. - - the testing proceedures for RMS has improved eliminating some of the electronic noise in the system. - - k-lab processing can actually show a slight increase in grain as well.
