Ilford Ilfotec HC Users
I have just purchased some Ilfotec HC as I need something with a longer shelf life than Ifosol 3 due to the fact I am not having much time to shoot film let alone develop it.
I am after some advise on using it as I would prefer to use it as a concentrate and mix when needed rather than using a stock solution. So is there anyone on here that does this and can you offer any advice as I have not used it before? Thanks David |

David, just straight out of the bottle is fine. I've always used it as one-shot. It keeps extremely well if you use Protectan (lots of discussion available on the forum).
Pretty much any grad will do for initial mixing, as long as it can take the same again in water for several dilution steps. |

Coincidentally, I've just opened a 500ml brown glass bottle of Ilfotec HC I decanted more than 10 years ago! It's worked perfectly for the 30 sheets of Delta 100 4x5" that I've rotary processed so far. And I'll be processing another 30 sheets of Tmax 100 this weekend before making some prints.
I use a syringe to measure accurate volumes and dilute 1+49 for one-shot use and easy calculations.

I know this is not what you are asking but I would recommend that you keep some 1+3 stock solution handy and then mix 1+7 for a standard working dilution B as you need it. If you keep the stock in an airtight container it lasts for months. Empty crew top Caprisun 330ml or 500ml pouches for example are great to squeeze out all the air. Then when you need to develop, it is super quick to mix and achieve consistency in your concentration.

AFAIK the two are much the same, although I've always used HC 110. So use the times Ilford say, see how you go, and if you need any more look at the HC 110 times. Neil.

The reason I turned to my 'vintage' Ilfotec HC is that my new full bottle and a half of Spur HRX was a deep yellow colour, even though one was completely sealed and in its original packaging.
I did a clip test and clearly of the two, the Ilfotec HC hadn't lost its potency, by comparison. Spur HRX is a fine developer but I find its shelf life on the short side. I'm looking forward to giving the Kodak Xtol clone, Adox Xt-3 a run for its money but after that I'm going to stick with standard, run of the mill developers, like good old Ilfotec HC!

Leaving aside the question mark that may or may not hang over the "new" HC110 in terms of its longevity v "old" HC110 and how this alters its longevity v Ilfotec NC, what I am unsure about is whether leaving Ilfotec HC in its concentrate form is better from a longevity aspect than diluting it to stock at 1+3 and then further diluting it to working concentration.
I'd be interested in any opinions either from a theory aspect or better still from those who may have tried both methods. Intuitively it seems to me that introducing a lot of water such as 500ml or 1 litre as Ilford suggests would affect its longevity adversely but intuition isn't always a reliable instinct However from the convenience aspect in terms of measurement it struck me that if you use the 1+47 dilution from stock at 1+3 this makes the maths a little harder as compared to 1+50 which is much easier. The two methods do result in very marginally different dilutions, I think, but at these kind of dilutions i.e. 1+3 then 1+ 47 v 1+50 the difference might be so marginal that it can safely be ignored Any comments are appreciated Thanks Mike |
