HP5+ in D-76 ...starting over with 4x5 -- where to start w/ JOBO

[pchaplo]

I just shot a test bracket with HP5+ 4x5, metering at ISO 250 that i heard many people use as a working film speed. I plan to develop with D-76 in a Jobo processor as my friend has D-76 on-hand and will help me. If you have worked with this same film, developer, and processor could you kindly advise on development time? Also, when I shoot the finals, I was to process them archivally--does that mean that I wash them for extra long time or is there more to it?

For a starting point, follow the guidance in Ilford's data sheet for HP5 Plus:

Read the whole thing carefully - pretty much everything you need to know to get started is in there.

The label on my cabinet says: HP5+, EI 200, D-76 1:1, 73 F, 7.5 minutes. I use a JOBO drum and reversal rotary processing for both 4x5 and 8x10 formats.

I would ask what the OP wants to do with these negatives. GSPs? Scans? Alt Pro? 'It Depends' seems to be the real answer to his question.

Thanks. It seems obvious but I thought I would ask: 1:1 means one part developer to one part water, correct? Do you get D-76 as a powder or liquid concentrate? (I ask bc years ago I used HC-100 liquid concentrate that was very handy for single batch processing). What about the D-76?

Historical documentation. Mostly I need a well-exposed archival negative. Secondly and far less important, a contact print or a scan.

Do you process B&W film differently for different outputs? How?

[Kimberly Anderson]

Oh sure, you have a whole slew of developer options, exposure options, developing technique options, many people like to tailor their system to match the type of output or prints they want to make.

It's like anything, you can dive into a death spiral of obsessiveness from which you may or may not recover. No promises.

Yes, it is one part developer and one part water. D-76 is a powder that needs to be mixed with water.

Yes, it is one part developer and one part water. D-76 is a powder that needs to be mixed with water.

Thanks. Does D-76 dissolve easily? Do I need a mixer on a drill? Can I use tap water -- we have pretty good water here.
