Development time for HP5+ 400 pulled to 200

[malvin_latief]

Hi all, what is the recommended time for pulling HP5+ 1 stop to ISO 200?

Developer used is D-76.

 

Thanks all.

Depending upon your camera/lens/meter combination an ISO of 200 is the Exposure Index I always use for HP5. Expose for the shadow, develop for the highlights. Meaning, at 200 you'll be sure to capture shadow detail and developement times will vary on how much contrast you want. I use a Canon A2, set to ISO 200, adjust metering up or down dependent on the relative white/dark in the scene, and develop at 68 F for 8 minutes. However, this is also set to my enlarger and printing preferences. Some reading on the Zone system will help you if that doesn't all make sense. Go to www.zone2tone.co.uk for a well written discusion of this. Good luck.

Looking at your folder I'm guessing you already have the Zone concept down... Forgot to mention that I use stock solution, no dilution. Are yu familiar with the Massive Development Chart? www.digitaltruth.com

Reduce processing time 33% the normal for EI 400.

 

Good for shooting polar bears at high noon on black asphalt.

For 35mm hp5 plus rated EI:200 a processing time of 9 minutes

in d-76 1:1 @ 20 degrees celcius should get you in the ballpark.

You can extrapolate from there. This time is for processing

without a presoak & printing on grade 3 paper with a diffusion

enlarger.

 

I dont consider this to be a " pull process " for me it is

the way the film works best , both in practice and also according

to sensitometric evaluation.

As Scott said, reduce dev time by 33 percent per stop

downrating. At 1+1 this should give you a dev time of 8.5 minutes

if I remember rightly.

I develop HP5+ exposed at ISO 200 in ID-11 (1:1) for 11 min. Agitation 2 inv./30 sec.
