Kodak HC-110 & Ilford HC

Anyone care to comment on whether Ilford HC is to Kodak HC-110 as ID-11 is to D76? Are HC and HC-110 pretty much the same? The reason I ask is that Ilford's datasheet for FP4+ states 8 mins done in Ilford HC and 9 mins done in Kodak HC-110, both at 1+31. DigitalTruth says 7-9 mins, which is a large variation for a short development time!

I developed my last HP4+ in Kodak HC-110 (310ml water to 10ml developer) for 9 mins and I feel it is slightly over-cooked. I'm going to try 8 mins next time but thought I'd seek some opinions first.

The HC-110 formula is a trade secret and has not been duplicated.

Ilford's HC is not a drop-in replacement, but should give similar results to HC-110, once you adjust times/temps/dilutions for the difference in formula.

The two are market equivalent in terms of dilutions and recommended times, though it is unclear whether the two are equivalent for results. I have never used Ilfotec HC, but what I do know is that HC-110 is considerably less expensive* here in the U.S, so we have little incentive to give it a try.

So true, or at least a true duplication has never been proven. Let us hope that HC-110 continues to be made or that the recipe passes into the public domain at some point. Truth be known, what I truly desire is a return of or a true duplicate of Edwal FG7. It abruptly disappeared from the market a few years ago with nothing but rumors regarding why and whether it will ever return.

Thanks, folks.

I usually use ID-11 but it goes too quickly, even at 1+3, before I'm mixing up another lot of sherbet, so I thought I'd give HC-110 a go as it's meant to last a long time and a little goes a long way. I use Adox Rodinal too. I've never used Ilford HC. I can only try a shorter dev time and find out for myself!

Kodak HC-110 is an iconic, unequaled (imo) developer with a dozen+ variations, depending on the cook in charge. There are many other HC developers, but HC110 is kind of the “Gold” standard. Dozens of recipes and help sections exist for it. The concentrate lasts a long time, if needed. I remember when a small bottle was several dollars but made gallons of Tri-X mix for me. I can almost smell it,aahhhh! :-)

There's also LegacyPro L-110 thats very similiar to Kodak's HC-110. Same dilutions, dev times, though LP's 100 is not as thick as Kodak's 110. From what I've read online, they're both give similiar results.


Plus, LP's version is cheaper at $14:

A tale of two photographers. One says he gets perfect exposure and prints when he develops his film for 8 minutes. Another says, rubbish, he uses the same film and developer and also gets perfect prints when developed at 11 minutes. And both are correct.

They both photograph chess boards.

Yes, cheaper, but I've read reports that LegacyPro L-110 has a shorter shelf life than Kodak HC-110.
