Pushing HP5+ to 3200 in D76?

[PaulRicciardi]

I've got a roll of HP5 (35mm) that I shot a while back at 3200 and still haven't developed. I would have, but I'm not too sure on the developing times. I've pushed HP5 before in D76 and Diafine but never to 3200.

So, my question is, anyone done it? I've seen HP5 pushed to 3200 but it's always been in Microphen or Rodinal. And while Rodinal would be my preferred developer for doing this I've actually never used the stuff nor do I have access to it. All I've got is D76 and Diafine both of which I am very comfortable with. I'd rather not add another developer just now especially since I don't push this far very often.

I would like to go ahead try it in D76 but was wondering what you guys would recommend for times. I was thinking ~21 minutes in D76 stock. Any opinions?

Thanks, I'll be sure to post the results

I've done it before with decent results. If I'm not mistaken, I think my times were 25 minutes at 1:1. I'll have to check my records for that though....

Both Ilford & The Massive Development Chart list times for HP5+ in D-76 at ASA 3200. I'm not sure if they list a time for D-76 1:1. That would be my choice. Hopefully Derrick comes through with his times.

Where? I don't see anything on my Ilford chart for HP5 in D76 at 3200 nor is there anything on the Massive Dev Chart. Those were the first two places I checked.

Here is the link to the HP5 chart- the column for HP5 at 3200 in D76 is blank for all dilutions. The MDC maxes out at 1600.

Derrick?

Sorry for the late reply; I was at a shoot all day.

Yup, just checked my records. 25min at 1:1 for HP5 in D-76 pushed to 3200. I've only done a few rolls of HP5 pushed to 3200 in D-76, but it seems to work well with these numbers. As with anything thing you're not sure of, try some test rolls before developing anything important!

Let us know how it turns out!

Ilford says 20 minutes in ID-11 for HP5 at 3200. ID-11 is D-76 under another name. Ilford lists slightly longer times for pushing HP-5 with ID-11 than for D-76, so as has been said, you might try a test roll first, or let this be your test 🙂 I wouldn't worry about totally ruining the roll. If you find the highlights are a bit more blown than you'd like, cut back on time a couple minutes. You biggest issue is going to be insufficient exposure, not poor developing, in my experience.

The worst that could happen is some highlights get slightly more blown out if the shots were of a high-contrast scene. But with times that long, a few minutes either way will have little effect on the result - IOW, if 18 minutes would have been "ideal," you will hardly notice the difference at 20 minutes. And if 24 minutes would have been "perfect," 20 minutes will still get you so close to "perfect" you won't see any real failings unless you had another roll shot in the same conditions done for a different dev time.

Good luck!

I didn't realize ID-11 was D76. Learn something new every day!

Thanks for the advice guys, I'll try it at 20 minutes tomorrow and let you guys see what happened. There's nothing terribly important on that roll of film so it can be the test.

Sorry. I was trusting my memory. Always a risky thing for me. 😱 🙂

Anyway, as you pointed out, all the information for D-76 and HP5+ stops at 1600.

I never tried 3200, but I do use HP5+ at 1600 in DD-X 1:4, I've tried a couple of rolls at 800 and 1600 in D-76 1:1 but found DD-X to be much better. However, that's just because I used DD-X first - I'm sure sienarot's times will give you something you'll be happy with.

My recollection is that D-76 was normally used by diluting the basic mix 1:1 for use. Compared to some other developers that could be used at varied dilutions, I'm not sure D-76 was ever meant to be done that way. But there must be somebody around who "forgot" to dilute it. By doing that and/or extending the time in the soup, surely you could up the effective ISO. But I would do some experimenting before I did it with once-in-a-lifetime negatives.

I am wondering if you were better of with Stand Development. HP5 does not have the finest grain to begin with and pushed to 3200 and then developed in D-76 might give you huge grain. I would test with R0dinal 1:100 stand developed for one hour. Just a thought.

...Ilford lists slightly longer times for pushing HP-5 with ID-11 than for D-76...

I always thought that was so you'd get better results with ID-11😀

I'll agree on watching the agaitation- I'd give it way less for the bulk of the added time, my standard for all pushes. This is a big push though, Microphen would be my choice.

Good luck.

Yeah it is a big push for sure and Microphen would be my choice too but, like I said, I don't have any. There's really nothing important on the negs and so I figured it's worth a shot even just as an experiment. I'll be sure to pay attention to agitation.

D76 is generally diluted to 1:1 but you can use it as stock. Not really supposed to but it is quicker. I've also read in a few places that higher speed films (ie delta 3200 and TMX 3200) take better to D76 stock as opposed to 1:1. In any event I'll probably try this roll at 20 minutes stock, minimal agitation tonight after classes and put the results up for you guys.

Thanks a lot.

Why HP5+? There are a number of better choices - Delta 3200 or Neopan 1600 come to mind.

My feeling is that Tri-X is better for serious pushing than HP5+. You don't get much shadow detail with HP5+ at 1600, even in DD-X. This is HP5+ at 1600 in DD-X 1:4 (11.75min at 21C).

Because I have already shot the roll of HP5 at 3200...
I wanted to shoot at 3200 and had no other choices but HP5. I have some Neopan 1600 now but at the time I shot this particular roll it was HP5 or nothing. I'd rather have something than nothing!

Since you have already shot the film, I think you will have better luck (and you will need a big dose of luck) to use a high energy developer like Acufine.
