D76 versus ID11, Are they the same things ?

D76 versus ID11, Are they the same things ?

 

[koraks]

Yes, as discussed many times on this forum and others.

 

[miha]

Oh come on, @koraks, you know it’s not that simple

 

[koraks]

I know; just wanted to set the record straight before we embark upon a 12-page journey that will lead us past Scylla and Charybdis, plenty of cyclopes and perhaps a siren or two.

 

[miha]

Let’s not get ahead of ourselves, the voyage hasn’t even started yet, and the monsters are already lining up!

 

[brian steinberger]

It’s always been said they are the same but in my experience I find ID-11 to be more active and produce more film speed. I don’t know why that would be, and honestly don’t care. I just use ID-11.

When ID-11 was hard to find last year or maybe the year before I purchased some D-76, that was Sino made D-76. I used it just like I would ID-11 and got thin negatives.

So IMO they’re not exactly the same, but I’m probably the only one that ever noticed this. And it could be because of the quality issues with Sino making kodaks chemistry. I would recommended getting a pack of each and see for yourself.

I believe much of / most of Kodak photo chemistry is presently being manfactured by Photo Systems Inc. who are based in Dexter, Michigan. But I am not certain that applies to D-76, specifically.

If you get rid of the I and add a horizontal line to the top left of the first 1 of 11, then add a small circle onto the bottom right of the second 1, you'll get what ID-11 really is.

 

[Agulliver]

They should be functionally identical though a proficient analytical chemist might find differences between the two.

That's evil.

 

[Craig]

They are functionally equivalent. You can safely treat them as the same.

Sounds like a Confucius saying

I did compare ID 11 and D 76, that was several decades past, and found that Kodak made D76 and ID 11 to be so close that I could not tell the difference. This was before Kodak sold off it's chemistry division which has gone under several new producers over the years. I used D76 as it was cheaper at the time. As I recall from P.E posts is that commercial D76 had additional buffers. If OP is mixing from old posted formulas there may differences from commercial kits.

Ilford doesn't give the same developing time for D-76 and ID-11.

 

[runswithsizzers]

My sources in the US tend to price Ilford ID-11 slightly higher than Kodak D-76, but it's not enough for me care about. If my math is right, ID-11 only about $0.50USD per liter more expensive.

Ilford says capacity of a liter of stock solution is 10 films "provided that the developer is reused"
Kodak's data sheet says 4 rolls /liter. Hmmm...

The only other consideration for me would be shelf life of the stock solution. The latest data sheets I have say:
Kodak D-76, publication J-78 (revised 12-2017): Stock Solution in Tightly Closed Bottle (full) = 6 months
TECHNICAL INFORMATION PERCEPTOL, ID-11 AND MICROPHEN FILM DEVELOPERS (Aug 2024): up to 6 months in full capped containers
Ilford says "up to" six months, so a maximum. Kodak does not say if their "six months" is a minimum or a maximum.

I just developed two rolls of 120 in some Kodak D-76 which has been kept in full amber glass bottles since I mixed it up on 9-14-25 -- so almost exactly six months ago; worked fine.

 

[cliveh]

D76 and ID11 have a very similar formulation, but D76 is the dogs bollocks of developers and ID11 is a close second.

 

[Paul Howell]

Ilford doesn't give the same developing time for D-76 and ID-11.

I just check, seem that the ILford data sheet for HP5+ has the same times for ID 11 and D76 stock at 68 degrees 7 1/2.

Stock, yes. But not at 1+1 or 1+3.

And not pushed at 800.

D76 versus ID11, Are they the same things ?

Yes.

 

[Don_ih]

I've used both. They behave the same as homemade D76.

Why does this keep happening??!

"This life as you now live it and have lived it, you will have to live once more and innumerable times more; and there will be nothing new in it, but every pain and every joy and every thought and sigh and everything unutterably small or great in your life will have to return to you, all in the same succession and sequence."
— Friedrich Nietzsche

Because of the rare sighting of a siren on journeys like these.
