pulling hp5 - questions

[jwchayse]

there is no info on the massie dev chart that i can find about rating hp5 at EI 100.

does anyone have any experience they can share? or is this not a good film to pull that much?

thanks jon

By the way you've posted I assume you've not yet set the EI rating. If so I'd be inclined to try a 100 rated film instead. You are probably asking too much of HP5+, pulling it two stops if you want best quality. I suspect that the fact that there nothing on the MD Chart reinforces this.Usually if you want two stops slower then it's best to use film rated for two stops slower. You could try Perceptol at EI 200. HP5+ looks very nice this way.

If I wanted to have a 400 film that has this kind of versatility then based on another thread, I'd go for XP2 plus. The best range for this seems to be 200 - 800 but it's reputed to be still OK at as low as 50 so 100 should be within its tolerance range.

Ive found that HP5 look that good below say ei 250 or so in HC-110 and/or beutlers. but, it looks great at 400 or pushed to 800 in beutlers.

Dear Jon,

Why do you want to overexpose and underdevelop that much? What is your subject matter? What advantage do you expect to see? What format are you using? How are you metering? Until we know a little more, it is hard to give any advice on what might and might not work.

Note also that in popular developers the ISO of H5 varies from 250 or under (Perceptol) to almost 800 (DD-X), and that a slower film in a speed-increasing developer will normally give finer grain and better sharpness than a faster film in a speed reducing developer. What is your objection to FP4 (ISO 200+ in DD-X, 80 or so in Perceptol)?

Cheers,

Roger

I'm assuming you already exposed the HP5 as 100 by mistake and want to get information.
You are also not indicating which developer you plan to use.

I would try to develop as 200 in a diluted developer (HC 110 dilH) with decrreased agitation, or in a developer such as Microdol-X
You'll get negatives tha are a bit overexposed but there will be plenty of information

Thanks for the feedback everyone.

I realized I may have been asking the wrong question. Essentially I just want to lower contrast. Ill be in chicago for about a week and shooting in the street, so.... shade from buildings next to open sunlight on reflective surfaces.

I just want to hold plenty of detail everywhere. So if I expose hp5 at 400 putting the shadows around Z3 or4, by minusing development as if I were pulling the film I'd be the making sure the highlights ended up in a safe place, right?

Shooting 35mm, in D-76.

This is all hypothetical if I get there and find that the brightness range of the scenes isnt that huge, but if it is, I want to know what to do with the film.

Thanks
Jon

Dear Jon,

With D76, EI 200-250, and 15-20% off the dev time, will give you easy-to-print negs almost anywhere -- even in brilliant midday sun in towns and cities, as long as you favor the shadows slightly when metering, i.e. don't meter white walls. Any further increase in exposure will merely increase grain and reduce sharpness.

Cheers,

Roger
