Well, yes I suppose there is no reason for Ilford to have to worry about other people's copyrights on formulas, they will surely have all the knowledge they (We!) need in their knowledge banks going back a hundred years or so! Maybe we don't really need the Kentmere formula as without the factory and the production techniques it may not be so useful as we might hope - but it would be nice to know how to make POP stable and increase the shelf life and so on...
If there is genuinly too small a demand to start up any sort of production ever again, for Ilford or anyone else, then where is the harm in releasing some knowledge?
So much technology dies when companies go under and product cease to be marketed. How many gems have we lost? There isn't much any single photographer can do about something like polaroid film or ektachrome, but so many wonderful developers have died with thier manufacturers or been withdrawn that could have been self mixed
I wonder if it would be feasible for someone from Ilford to give a talk on emulsions at the next open day? Maybe answering a few questions and dropping a few hints for emulsion makers?
We know how very supportive Ilford are of their customers, that would be a different, but bold, type of support. In the same way that they organise competitions and exhibitions it is doesn't directly make them any profit, but it can only help increase the enthusiasm for analogue photography... just a thought.
