Thank you, NB... I saw the previous mention... Do you use it? I've heard it has short life, but I have not used it... Why does it produce bigger, sharper grain?
Thank you, NB... I saw the previous mention... Do you use it? I've heard it has short life, but I have not used it... Why does it produce bigger, sharper grain?Just because it seems to have been totally ignored, ILFOSOL-3 will give you what you want. Big, sharp grain.
I tried to develop some grainy stuff today.
I tought Rodinal cannot expire? Got some heavily underdeveloped negs. Rodinal bottle had some hard crystals rattlin in the bottle.
How long did you leave the working solution to sit before pouring into the developing tank? The current ADOX Rodinal has at least an 18 month life expectancy from my experience - though I've seen crystallization in Foma's RO9.
Actually, yes. I left it for maybe 15 minutes. Is that the reason?
It has a little higher ph than D-76, and users' reports talk about low speed... From what I've read it's people who scan who find big grain... Do you have any wet print grain sample?Just because it seems to have been totally ignored, ILFOSOL-3 will give you what you want. Big, sharp grain.
I've seen Rodinal mixed to working strength die completely after 30 mins or thereabouts (hence why most of the stand developing claims are questionable).

If I remember well, lowering the amount of sulfite in D-76 for less solvency effect brings the problem of reduced shelf life...
This makes me consider the best option for adding a chemical to an already mixed developer could be adding it just before its use: I mean adding the chemical only to the stock volume we are about to use for mixing -with water- the one shot dilution... Has someone done this?
I can't talk directly about commercially made Rodinal clones (though I doubt it's a myth for them, either), but Parodinal (homebrewed work-alike) certainly does support one hour stand development -- I've done it. Now, I can't say it isn't doing all its real work in the first 15-30 minutes (at 1:100 dilution, it would run above 15 minutes with normal agitation anyway), and then dying -- but that's partially the point of stand development: local exhaustion, to limit contrast (especially by shouldering off very high exposure) and produce edge effects that enhance apparent sharpness.
Now, I've never mixed working solution Parodinal and then left it to stand in the graduate for more than long enough to fill the stop bath and fixer graduates, verify temperature, and set the timer -- but at 1:25 or 1:50 I wouldn't expect thirty minutes to be a problem. I've left Caffenol (the non-ascorbate original version, which is completely free of preservatives) for fifteen minutes or more, to settle micro-bubbles from the laundry soda, and it works fine -- though I don't know of any reason I'd leave it for an hour, since it doesn't lend itself as much to stand development.
No wonder, as this is a hack. Making a variant of a developer that is known for its relatively small grain on 400 films would defeat its original purpose. However, Microphen is still a phenidone-hydroquione developer, and at higher pH it will give a big sharp grain if diluted and supplemented with alkali.Has anyone a link to any article or text about adding Na2CO3 to D-76 or Microphen, to get bigger sharper grain?
I couldn't find a word on it...
Thanks.
Oh yes, sure it makes sense... I was just thinking -precisely- this may be common, so someone must have written something to give a general view on the subject, pros and cons with a few developers, good and bad films for it, etc...No wonder, as this is a hack.

That's great!Here is one print from my tests.

What do you think of the grain?
I shot two rolls of Fomapan 400 at ISO 160 and overdeveloped in Rodinal 1+25 for 7 minutes with 30 second agitation sequence.
Whatever dilution you decide to use, you need to determine the new development time for box speed. For example, D-76 1:1 plus 2 g/L soda would develop a 400 ASA film in 5-6 minutes instead of the suggested 11-12.Well, then I'll need to lower my dilution beyond 1+1.5... Thanks
It's been fun, and you're right: adding Na2CO3 is like giving development a new empty highway... Everything happens quickly.Whatever dilution you decide to use, you need to determine the new development time for box speed.
