Developing Plates
Posted: Wed Nov 23, 2011 6:34 pm Etc/GMT-1+01:00
Hi all.
I have been asked to take a portrait of the vicar at church, to go up in the sacristy alongside those of previous incumbents, dating back to 1860's. As I don't particularly care for colour pictures of clergy (!) I thought I'd do something a bit more traditional. In the loft I have a few packets of glass plates, 1/4 plate size which are just right for a contact print to match the ones already there.
As I don't want to waste too many, does anyone have a tip as to test for development times? The plates probably date from the 1920's or 30's. The emulsion speed is given in Hurter and Driffield, and Ilford speed grouping, but presumably this will be somewhat out, given the age of the plates.
Just as an aside, in the church's graveyard rests the widow of John Scott Archer of wetplate fame, but I'll have to wait until next year before I learn how to do wetplate negs!
