I metered for zone 1 and made an exposure, as well as exposures 1.5 stops above and below this reading in 0.5 stop increments. After processing, I metered each exposure with a one degree spot meter. The zone 1 exposure that gave me about 0.09 above base+fog corresponded to a film speed of 100. This was just one test so I havn't tried to see if it was repeatable yet. I also don't know how much density the stain added, so again my results are suspect. Is my use of the 2:2:100 dilution the correct one for printing on azo, or should I be using the 1:1:100 dilution? Thanks for any help you can offer.
