HC-110, Delta 100, please help

[tijean]

Call me clueless, but I am lost here. Loaded up my film, mixed fresh

chemicals, pulled up the data sheet for the film I was using to

check the time and...

 

http://www.ilford.com/html/us_english/pdf/100_Delta.pdf

 

Under dilution it just says 'B'

 

Huh?

 

The stock solution is mixed 16 oz of concentrate to 240 oz water

(total of 2 gal.)

 

I am using HC-110 for the first time and Ilford Delta 100 for the

hundredth.

 

Pleeeeeeeeease oh please give me a clue, cos lord know I'm missing

one right about now.

HC110 dilution B is one part concentrate and water to make 32 parts. For example:

 

1 oz concentrate plus water to make 32 oz working solution

 

or

 

1/4 oz concentrate plus water to make 8 oz (my usual)

 

Small qty's from concentrate (such as the second example) are fairly doable with a small capacity syringe.

Hiya Jessica,<br>

What I do is NOT mix a stock sollution. I mix directly from consentrate.<br>

Here is a table for mixing directly from consentrate:<br>

The dilutions are all listed in the side of the HC-110 bottle!

[jordan_w.]

Have a look at the link Glen provided. Kodak's "official" advice with HC-110 is to mix a stock solution first by diluting the thick syrup that comes in the bottle with a certain amount of water, then use this stock solution in various dilutions to get the working solution for developing. It seems like that's what you have done. Most people, though, ignore Kodak's advice and just prepare their working solutions directly from the thick syrup. In the latter case, dilution B is prepared by mixing one part syrup with 31 parts water (this is for the version of HC-110 sold in North America, the UK/Europe version may be different).

 

Have a look at the Covington site (Glen's link) and I think most of your questions will be answered.

Thank you everyone so much for your help. It's very strange to me, coming from D-76 powder, that you can mix for each individual batch. Very strange, but quite nice. I guess my solution 'B' (working solution for Delta 100) is just about 1:1 with my stock solution and water. I may do what Jordon mentioned though (mixing working solution and skipping the middle step) since I tend to develop in batches, or go for Mendel's way for small runs.

<br><br>

Guy, the only instructions on my bottle are for making what appears to be dilution 'A' though it is not labeled as such.

<br><br>

Thanks to unwavering time restraints and the knowledge that there weren't any irreplaceable shots, I went for the <b>very</b> scientific <i>pour it on in and cross your fingers method</i>. I still need to scan (I scan all for contact prints and 'net quality images, and then head down to the college darkroom to print any I want to print), but just with a 12x loop, they look like they are not too much worse for wear, though the poor battery on the camera was dead so metering was as much semi-educated guess as anything else. Not many controls in that little experiment, but with the info here, I can do it right next time!

"It's very strange to me, coming from D-76 powder, that you can mix for each individual batch"

 

I thought that was a no-no. That there was no guarantee the powdered ingredients were homogenized. If it works, a good approach, though.

[lex_jenkins]

I you plan to develop enough film during a one or two week run, it's probably easier and more precise to mix up a larger batch per Kodak's directions rather than mix individual batches using a dropper or syringe to make a single tankful at a time.

[mendel_leisk]

Thought for an invertion: water soluble 1/4 oz gel caps of hc-110.

 

Airtight, precisely measured, no muss.

[mendel_leisk]

HC-110 being itself water based could cause problems with that idea, I suppose. LOL!
