Digging deep into the freezer three days ago, I came across a 20 roll 'brick' of Kodak's HIE that I removed from a 'commercial' deep freeze storage (-30C) six months ago after having forgotten I still had it in 'storage' since I rarely, if ever use 35mm films any more, (now being well and truly 'retired') and was 'somewhat' unwilling to fork out their latest 'increase' in monthly storage fee from my pension income.. and I have not 're-invested' $$ in Kodak's E-6 'Kit' for a few years...and there's no 'local' E6 processing available any more.
