Thanks for that Barry.
Have you tried E72?
It is (apparently*) a more environmentally alternative version; I've been using it for quite some years now.
750ml Water 50ºC
Sodium Sulphite Anh 45.0g
Ascorbic Acid 19.0g
Sodium Carbonate Anh 77.0g (or mono version with 90.0g)
Potassium Bromide 1.9g
1:1 for high contrast, which is my standard way of using it, 1:2 or 1:3 for lower contrast. Using it at 1:1 puts a snap into my prints.
I also use this paper developer in my Durst Printo roller transport paper processor at 30ºC with 45 seconds development, straight into fixer for 45 seconds then into some trays where I hand wash, followed by a quick trip through a paper dryer.
* Apparently as I don't really know, it is just what is touted.
I use Sodium Carbonate anhydrous, as it is what I have on hand.
I get my Ascorbic acid from the local chemists, cheapest way to get small (ish) amounts. I usually check out online then head into the local shopping centre chemist and eyeball who is the cheapest chemist shop.https://www.superpharmacy.com.au/produc ... ErEALw_wcB
