Our local photo supplier (Vanbar, Melbourne) has potassium ferricyanide for $44 per kilogram, so it doesn't have to be expensive (Australian dollars, not real dollars).

I use an older 12x16 Nova and that limits my paper size. I'm reconciled to that. As much as I enjoy mine, I've read some negative comments about the new model, but I know very little about it.

Should that be bisulphite (i not a)?

If so, metabisulphite is more available (brewers' suppliers)
