HP5+ in D-76

Mike Kennedy · Nov 18, 2008

Would appreciate users of this combination to give me some advice.Should I rate the film at box speed? (not a lot of sun today).

Thank You

I rate it at 320, but box speed is s close to that you'll probably be ok. Best if you bracket on your first roll, just in case (my speed is based on the meters I use, yours could be different).

Thanks Chris.
This is weird.I went to school with a guy named Chris Crawford.........small world eh?

Hello Mike,

Hp5+ is my favourite film. In 35mm I develop it in ID11, which I believe is the same stuff as D76. I dilute it 1 + 3, which I find gives little or no increase in grain over 1 + 1, but a noticable increase in sharpness, and seems to produce negatives which are remarkably easy to print. I rate the film at 200. Development times are 14min. for strong sunlight, 16min. for hazy sunlight, 20min. bright but no sun. I develop at 20 degrees C, and invert the tank once every 30 seconds, after initial 5 inversions.
I believe this is as close as you will get to a magic bullet!

I agree with AlanC. I only occasionally vary from HP5/ID11 and it works for almost everything. I usually use it at 400 in ID11 and 1+1 for anything from 12 to 16 minutes, depending on the level of contrast you want. You haven't said whether you'r using 35mm or larger, but I find 35mm is better at a slightly lower contrast (less development). I suspect Ilford's times are optimised for 35mm from experience, though.

Try it and see!

No ID11 in my city.
Might see if I can order some from Henry's but,Christmas is just around the corner and I have to watch my pennies.

HP5 in D76 stock @ 20C: ISO 400=7.5min, ISO 800=9.5min. Personally, I prefer my developer and whiskey straight (and neither my grain nor brain are mushy).

I get good results with HP5 at 200asa in D76/ID11 1+1 for 11mins at 20c. I have used D76 at 1+3 and although it has a long tonal scale, there is (IMO) a noticable increase in grain.

AlanC · Nov 18, 2008

Blighty,
Did you also notice an increase in sharpness at 1+3? As I have said, I noted hardly any increase in grain, and would describe my 35mm prints as fine grained-certainly quite a bit finer than Pyrocat HD, which some people describe as fine grained. In fact, I use Pyrocat with 35mm HP5+ when I want more grain.

My wife and I used to teach a basic photo class for teenagers, and used this exact formula with 35mm - very forgiving, you almost always get printable negs from it.

I shoot mostly in LF and process my HP5 in HC-110B.

I`ve used HP5 Plus in D-76 diluted 1+1 for years and the results are beautiful. I expose it at the box speed of 400 and never had a problem with it. I use it for portraits in the studio and develop it for 13 minutes at 20C/68F.

Thanks one and all.Great advice.
