Gianni Rondinini - 04 Apr 2005 15:56 GMT hi all.
yesterday evening i developed 2 of my delta3200's with rodinal. i used rodinal 1+25, 20°c. then i fixed for 8 minutes with ornano rapid fixer and the usual 6/7 minutes in agepon, agfa's wetting agent.
i must say the negatives show a good contrast and a reasonable tone, but i think that overdeveloping at least 1 minute may give better results, because the film seems a little bit dark to me. i'll "sacrify" a film for a deeper test.
a friend of mine insists that with rodinal you can deeply modify contrast and grain of the film and says that going to 19 --or even a bit less-- degrees and increasing development time by 30% would give far better results as grain and contrast --with fast films--. perhaps next time i'll give this a try.
chances are also that this wednesday evening i'll develop delta3200's @12500 with t-max developer --the ones we've been talking about some weeks ago--. i'll let you know the results on friday.
i hope i'll start printing soon --i still miss a red safe filter for enlarger lenses: my enlargers were used for color prints and have no safelight filter at the moment--.

Why on earth would you do that? You need 30 seconds max. with any wetting agent, whether Agepon, Photo-Flo or dish detergent. All you need to do is coat the film so the water film covers it all over.

"Sacrifice"? But surely you meant to say that _underdeveloping_ may give better results, because if the film seems a bit dark, then it's overdeveloped (or overexposed).
If the film seems too light, then you may want to try more development.

All you need to do well, after reading your post i read the sticker on the agepon bottle and saw that it says "30"-1'" :) i wasn't in a hurry to remove the film from the wetting agent and used to leave it there while i washed the tank and something else.

thank you.

This probably means 30 parts water to 1 part Agepon. Make sure it is heavily diluted. Distilled water prefereable. In fact I often just use distilled water only with no wetting agent

as diluition, i work at the recommended 1+200. never used distilled water, but i'll give it a chance.
thank you.

That's what I do with Photo-Flo, which is half the recommended dilution. I find the standard dilution is too strong and leave too heavy a film on the film.

>distilled water only with no wetting agent apr905 from Lloyd Erlick,
Distilled water is very useful in the darkroom. For final wash of films, it can't be beat. I hang my roll films in a dust free place, and squirt distilled water down both sides of each roll. I never use wetting agent, and I never touch the surfaces of the film while they are wet (this means no squeegee, no gloves, no fingers, touch the films). I have never found a problem from lack of wetting agent. Also, I have never seen a problem from any sort of mechanical distortion of the film from differential drying of droplets clinging to the surfaces vs relatively dry areas of no droplets. By the time the rolls are dry, they are perfectly uniform (and clean). Films currently manufactured are well able to dry uniformly with no problem. In fact, I believe a wetting agent is incorporated in the coating of modern films, although it would likely be gone by the time the film was washed. (I mostly use Kodak film, but I've never seen a problem from my washing and drying technique with Agfa or Ilford over the years.)
Wetting agent might be useful for final film wash in tap water, which might tend to promote water spots on the dry film (i.e., deposits of minerals from the water where it had formed droplets on the film and dried). Distilled water obviates this problem.
The ultimate final wash would probably be to immerse the film in distilled water while still on the reel. Two or three changes of distilled water this way and even the last vestiges of tap water absorbed into the coating would probably be gone.

pgg - 05 Apr 2005 00:10 GMT Rodinal and Delta3200 aren't a good match. The latter is a grainy film with a true film speed of 1000-1200 instead of 3200. Therefore you want a developer that extracts as much shadow detail (or film speed) as possible and dissolves grain. Rodinal does _not_ do this.
Ilford Microphen is a good match with Delta3200.

Rodinal may deliver results that you like depending on personal preferences. I expect it to be grainy, but you might like that.
Gianni Rondinini - 06 Apr 2005 16:43 GMT >Xtol is a great match for Delta3200. It delivers more film speed (shadow >detail) than Rodinal. ok, i'll stick to xtol for the next ones. i have it at home, so i can try. i've read good things also of tmax + delta3200: another possibility to try.
>Rodinal may deliver results that you like depending on personal >preferences. I expect it to be grainy, but you might like that. well, those are pictures taken at a live stage in a jazz club: *thick* grain was exactly what i wanted, but i haven't printed them yet, then i don't know how grainy the films are.
i'll let you know --and hope i like it...--.

ID-68 "Officially Modified": A mix; P and Q - .2 and 5 gr S. metabisulfite .75 gr. S. sulfite 100 gr. I think it, 'add the sulfite last' as the phenidone will more quickly dissolve in acid solution. B mix; Borax and Boric Acid 3 and 3.5 gr. P. Bromide 1 gr. A and B togeather to make 1 liter. Ph, 8.9 .
ID-68, a one solution mix: Drop the borax and meta. Use 2 gr of Boric Acid. I'd think it, 'add save but a pinch' the sulfite last.
Now there are at least three formulas for ID-68. Ilford's PQ Universal is the exact same as the above 'modified' save for no metabisulfite. The PQ Universal is a D76 and ID11B buffered equivalent. So what does it all boil down to? So far five D76 or ID-11B or ID -68 formulas which in use will likely give same results. Dan

I find Microphen to be very different than D76. I know it's not really supposed to be but I can't deny the better shadow contrasts I get with Microphen.

MIcrophen has better shadow and contrast control (and better grain if diluted) than id11.

That implies a shorter toe. In effect a boost in ISO is the result with phenidone. That is consistant with reports of higher emulsion speeds with that agent. Do you think that the case? Dan

It's really a good all-around developer. Not going to replace my D23 but it's the only other developer I bother with.

Stefano Bramato - 11 Apr 2005 15:49 GMT > why not? > > ps: where are you from? i live in faenza (ra) Ciao Gianni, here my personal variation recipe for id68 - Microphen type developer:
water 750 ml Sodium sulphite 100 g Hydroquinone 6.5 g Borax 8.0 g Boric Acid 3.5 g Potassium Bromide 1.0 g Phenidone 0.2 g water to make 1000 ml
I use it diluted 1:1. I've to solve some problems of storing, seems to be more prone to oxidation than packed microphen.
MOre suggestions and comments are very very appreciated from everyone here. Please mr Knoppow, as you are so expert gimme some suggestions!!

IMO, I would place the Borax into a completely separate solution which you would use for your 1:1 dilution. Like this :
Divided ID-68
SOLUTION A Water 750 ML Sod.Sulfite 100g Hydroquinone 6.5g Boric Acid 3.5g Pot.Bromide 1.0g Phenidone 0.2g Water to make 1.0L
SOLUTION B Water 750ml Borax (Gran.) 8.0g Water to make 1.0L
Use 1A : 1B to make your working solution. This will effectively stop oxidation as it does not progress in acidic environments.

Stefano Bramato - 06 Apr 2005 17:08 GMT Ciao Gianni, i can suggest to use Microphen or HC110 to obtain the results that you want. Microphen is quite good also when diluted 1:1 for pushing, only having care to developing in longer times and the geain is quite fine. HC110 have a finer grain that Rodinal (but worst than Microphen IMO) but is more active and the grain is very acute.
I suggest also to try this combinations.
ciao, Stefano
