EMetastman Kodak Research Fine Grain Developer 1925/6

Metol 2g
Sodium Sulphite 100g
Borax 2g
water to 1.6 litres

This was published a year or two before D76, essentially it's the same as D76 without any Hydroquinone and more dilute.

Thanks for both of those formulae guys.

Good to see the more Eco D76 though, especially as I will soon be trying to mix some of my own chemicals again, with the last time in the mid 70's when I was a teenager and attending an evening course in photography.

I don't see any date on the Eco D76 though Norm, so is it a new formula that he's come up with or has it been around and been well published? Anything that is better for the environment I am willing to try.

PS Just googled and found the originator of the Eco D76 Norm.

Not sure if its a new formula but anything that is less toxic to the water system is a good thing, see also http://www.film-and-darkroom-user.or...ead.php?t=1826

For an easy mix alternative, try D23.

The original link is now dead as the file has been removed from the website.

There was a complaint on another Forum about plagiarism.

It got so heated between 2 participants especially that I am convinced there will be only one of them left tomorrow morning after the duel on the bois de boulogne.

As usual, I think that the 'conversation' got a little out of hand. comments are easily misread and made to sound much worse than intended on the internet in general.

Personally I like to just stay out of them and let them burn themselves out.
