    Re: HC110 B with HP5+ @ 100

    Thanks for the specific explanation Rodinal... but it still sounds like an awfully tedious way to get from Point A to Point B. If it works for you and you're happy with the results, who am I to judge? But I'm not necessarily impressed that Saint Ansel did it sloshing developer around in his stinky ole Stetson cowboy hat. I prefer to be a little more up to date with my own options. HP5 has a somewhat long toe, so I've overexposed just one stop (200 speed) in contrasty situations, or more likely, use it only for moderate contrast scenes. An exception: I once liked overexposing and overdeveloping it in order to significantly increase midtone microtonality and edge effect in PMK, then tamed the result with an unsharp mask when printing. Stunning results, but now I'd rather just use TMY400 to begin with, which has a much steeper toe with better shadow gradation.

    This is a more flexible approach, but it may require more work in the optical printing.

    There seems to be a divide between extreme dilution(EMA/Stand) and normal dilution camps for developers, with no-one in the middle or consideration you may have 2 or 3 sheets to do instead of 4 or 1.

    I found that a compromise usung a middle dilution with Pyrocat M dilution 4:3:500 (instead of 5:5:500 Normal or 3:2:500 EMA) lets me use full box speed and process 2 or 3 sheets with 3-4 minute agitation cycles and process times between 11 and 14 minutes (12:30 Normal). It may not have the acutance of an EMA process but it does shorten the process enough to keep me engaged and without the rush of short times where in/out pour times can have an impact.

    With HC110 I previously used dilutions of 1:47 commonly or 1:63 and adjust time and agitation linearly to get above 10Minutes always with 4 sheets or a roll.

    Thank you. I think for starters I am going to try 1:63 but I have also been looking at some HP5 shot at 200 and that may work for the purposes I am requiring right now.

    FWIW, my standard HP5+ EI is 200 and developed in HC-110 dil. H (1:63) for 10 minutes at 71F. This would be for silver printing.

    You might want to consider using a developer with inherently lower film speed if you want a printable contrast range. HC110 may work highly diluted but it is a formula noted for delivering rated film speed at a variety of dilutions. Of course, if you can, run a test.
