HC-110 vs. D-76 question


I agree with Richard above. I have used it from a half filled, way past expiry date Kodak bottle when it is as dark as really strong tea, and it has performed like new.

There is a certain amount of water in the air above the fluid in a bottle of HC110. Some of it will be absorbed. I expect that once that water has been absorbed, no further amount will be, unless you add more water to that air. Repeated handling might result in that, but it isn't immediately clear whether there is any net improvement when you compare the handling involved in decanting vs. the handling involved when not decanting.

It is clear to me, though, that you waste more developer when you decant, because it is difficult to impossible to get all of the syrup out of each bottle.

It seems to me that HC110 either reaches an equilibrium with the water in the air above it when you leave it in a bottle, or only deteriorates due to that water at a very, very, very slow rate. I'm not sure that is the case for developers that oxidize due to contact with air.

If it will still flow, it seems to work fine.

It applies for Social Security.

Seriously you can always do a snip test with the dilution you use. But realistically HC-110 lasts practically forever and people use it to the very end of a bottle. I have used HC-110 that is years old. As for a visual clue I suppose it changing to a very, VERY, VERY dark brown color.

I have two bottles of HC-110.

The first bottle is about 30% used and has an expiry date in 2010. I top off with Protectan after each opening and the developer is now a light honey colour. Plenty of life in it.

The second bottle is unopened with an expiry date in 2014. Developer is still light straw colour and I expect to be using it for the next 10 years.
 
Ive never had a bottle of Rodinal or HC-110 go bad on me. Even when the Rodinal went inky black and the HC-110 a deep rich thick goopy red.

Richard, that is without doubt the FUGliest photographic goop I have ever seen. I swear I saw lumps. You say there were none, but I am suspicious.

Anyway, thanks for the vid. If that unholy fluid actually developed film, then I will no longer worry about the freshness of my HC-110.
 

As cheap as it is, this is way too much trouble. Just keep some powder on hand and mix new.
 
I just discover HC-110 Dilution H and I'm really happy with the results, still I'm missing something from D76... could be more shadows details and less grain?
 
To resurrect an old thread...ahhhhhhh

I started with D-76 and moved on to a few other. Tmax Dev, Rodinal, Caffenol-C, HC-110, but today after a few years I mixed up a bag of D-76 and developed some Tmax 100 in stock solution. I missed having deep contrast and I felt I was not getting it from other developers. I though HC-110 gave me sorta flat negative. No problem with Tmax Dev as such but it is expensive.

So, back to the old standby for me.
 
essentially the same results with both butI prefer D76 because, I cN mixed fresh from bulk chemicals.I usually try to mix a high concentration as stock and dilute it down to a working solution when I need it.
