    Reference notes you post in your darkroom

    ...(this in lieu of f-stop printing, which I think is overly-complicate and fiddly) Spoon recipes for my most used print developers (D-72 and ID-62) On the inside of a cabinet door, a printed page with developing times for various film/developer combinations from N-2 through N+2 as well as...

    How long does paper developer working solution last?

    You mean ID-78, which is the Warm=tone version of UD-62. ID-68 is Microphen. No prints like negatives are never developed to completion. They need to be developed to achieve Dmax, continued development past that just means mid-tones shift darker, and a slight increase in highlights, and any...

    How long does paper developer working solution last?

    ...but it has developed some nasty-looking precipitates. I as actually thinking of making E-72 when I'm done with that bottle. Similar to your ID-62, but without Hydroquinone or Benzotriazole and with Vitamin C instead. --- A "PC" cousin of the "PQ" developer you use. I'm not sure about doing...

    PQ Universal and benzotriazole question

    I have the ingredients to make up PQ Unviversal. I am seeing the recipe as ID-62 and there are two versions of this recipe. One regular mix and the other being 2.5 times the strength. Which recipe would be used toward the Ilford black and white reversal process for the first and second...

    Questions about Potassium Thiocyanate and Ilford black and white reversal

    ...30% sulfuric acid, if I can't get the bisulfate. I'll mix it down to 10% when ready to use. I have noticed two recipes for PQ: One is the ID-62 and the other being the PQ concentrated which is 2.5 times the strength. The instructions for Ilford reversal indicates to use PQ: at 1+5 for the...

    Questions about Potassium Thiocyanate and Ilford black and white reversal

    ...Originally I was going to use D-19 for the developer. Would a longer wash remove most of the thiocyanate before the bleaching step? If not I can go with the ID-62 formula/PQ formula and the Ilford instructions. I have all of the ingredients for that developer except for the benzotriazole.

    TD-30 B&W "Improved Dektol" paper developer formula

    ...there were complaints about colour shifts and increased warmth, as throughput increased and Bromide built up. They re-formulated ID-20P as ID-62, cutting the Bromide in half and adding Benzotriazole. With the tiny amount of Benzotriazole per litre it wasn't sold as a powder developer, the...

    TD-30 B&W "Improved Dektol" paper developer formula

    ...of Bill Troop’s formulas, it wouldn’t be old enough to pre-date “modern” papers (the past 40+ years). You can use Dektol, Ilford Multigrade, ID-62 or any number of old/new things and get the same results. It’s unclear whether or not any of the usual tweaks really did anything in the old days...

    Fomabrom variant, Multigrade RC Deluxe, and sparkling highlights

    ...Fomabrom Variant closer to that of RC Deluxe I exposed strips of paper, on the baseboard, under a Stouffer step wedge (31x0.1D), developed in ID-62 1+2 for 2 min at 20-22°C. I used an Ilford contrast filter grade 2 in all cases, since Ilford and Foma both indicate a range of 90 for an Ilford...

    Rodinal like paper developer that is DIY?

    Either D-72 (MQ) of ID-62 (PQ) stored in a wine pouch keeps 1 year, time enough to use 1 litre or even 2 litrre if reasonably active printing. Too simple?

    Anything similar to LPD for warmtone?

    While I surely hope LPD is still available (it’s by far my favorite), if I ever could not get it anymore I would try and mix my own ID-62.

    One-shot Liquid Print Developer Concentrate?

    ...aerial oxidation. The concentrate should last as well (or slightly better) as in factory packaging. Alternatively, get some raw chemicals and teach your friend to brew up ID-68, ID-62 etc. so he can mix fresh what he needs, when he needs it. The dry components keep indefinitely if stored dry.

    HC110 vs Ilford PQ

    Hi, I’m planning to use it as a film developer to achieve low gamma extremely low contrast for masking purposes. Film in question would be Foma 100, FP4 and Bergger Print Film.

    HC110 vs Ilford PQ

    Ian Grant describes Ilford ID-62 as similar to Ilford PQ-U. Full information on his site. That is the paper developer that I use. Good keeping properties, good image quality with Ilford MG and Fomabrom Variant. http://www.lostlabours.co.uk/photography/formulae/developers/devID62.htm From what...

    All my papers are suddenly fogged?!

    ...is not very fresh, the carried-over developer discolors. Use fresh everything or switch to a different developer. I switched to home-mixed ID-62 and D-72 and solved the problem that way. Despite Liquidol's reputation as long-lasting, I found it less than stellar in that regard as well...

    Bromophen - neutral | PQU - neutral-warm ?

    Hi Bernard, thanks for updating. These results are fairly consistent with my tests of PMT (the active ingredient in Finisher Blue) with MQ developers and Ilford papers. Depending on the amount used/required, some speed loss is normal given PMT is a powerful restrainer.

    Bromophen - neutral | PQU - neutral-warm ?

    Feedback. In the meantime, I have received some Moersch Blue Finisher and made tests. Fomabrom variant 111. Stouffer step wedge 0.1D steps. ID-62 1+2 2min @22°C. Amounts 0, 5ml, 10ml per litre of working solution. Executive summary. It works. Thanks to all those who gave positive input...

    Bromophen - neutral | PQU - neutral-warm ?

    First : Do not expand the thumbnails until you have performed the blind test. Replacing phenidone with metol in ID-62 results in a close approximation of D-72. Except for the restrainer(s), but read on. I've tested both and claim that the tonality is identical. But, (you will say) D-72 has just...

    Bromophen - neutral | PQU - neutral-warm ?

    You are correct in that contemporary papers generally have most of their characteristics baked in. Although I’m not sure how effective the usual suggested tweaks ever were in reality with older papers, in my experience those modifications do little (often nothing) to modify the colour of most...

    That's still pretty good, though! I mix the working strength developer stronger, store in fully capped glass bottle in-between sessions and replenish after each session. That way, it keeps going indefinitely!

    Ilford multigrade paper develper

    I will disagree :D But only because the bad thing about ID-62 (or ID-78 the warm tone version) is a Litre on;y lasts 4 printing sessions at 1+3. I typically mix a litre of working strength developer per printing session, topping up if needed. So instead I mix to commercial strength and use at...
