HP5 in HC-110, does dissolution H create more grain?

[gilgsn]

Hello,

I used to process HP5 in HC-110 dissolution B, but that was 27 years ago.. Recently I used it with dissolution H (1+63) for 11 minutes at 20C. My negatives are grainier than old ones I dug out from my dissolution B days... Has anyone experienced the same?

Thanks,

Gil.

I am in the process of printing some HP5+ negatives (120, 6x4.5) that I developed in HC110 dilution H. I have never tried dilution B to compare, but the grain on these negatives was fine enough that it was hard to distinguish with my grain magnifier, significantly finer than similarly processed Tri-X.

The general rule is: more dilution=more acutance+more grain (acutance is nothing else than grain clumping and Eberhard effect). This will be particularly evident with solvent developers (e.g. D76) that become non solvent as you dilute sodium sulfite beyond a certain factor. I read HC110-B works well with HP5. D 76 1+1 works certainly very well. If you like more sharpness, yet fine grain, try to see a review for HP5 in HRX 3.

Thanks, great advise!

I tried it with Dul E and at 250 ISO and I like it the most. However, I just finished developing 6x6 and 35mm shot at box speed with the new HRX and it looks good through the loupe. It has a long wait to be scanned or printed 🙁
