Thank you, this is obviously a viable option, because I am thinking along the lines of making POTA-like developer than can be "spiced" with a variable amount of hydroquinone, depending on the scene shot. Your use of stand development with Rodinal appears to be also in line that this film really does not benefit from agitation, as I said above. I did try Beutler, in a normal way and split, and found it too contrasty for my taste, although with a certain kind of soft light it may work.

Well, you said it, once you know you can handle a film and like it, it is probably the time to buy it in bulk. BTW, do you happen to be the owner/creator of the http://caffenol.blogspot.ca/?

Sorry to say but I am not the best friend of caffenol developers so it can't be me.
If I'd like to be a creator of a blog it would be possible a category of
www.verynicelook@tumblr.com with topics to neofin blue, and other beutler
formulations.

with regards

May be topics on beutler & Co. I'd like
to create as category of verynicelook@tumblr (without www)

Here is Tom Hoskinson's long lasting version of H&W Control that was on here but the link is now broken:

Solution A
Triethanolamine...................75ml
Hydroquinone......................0.32g
Phenidone............................2.2g
Triethanolamine to................100ml

Phenidone and Hydroquinone are soluble in TEA.
Warm the Triathanolamine to 80 to 100 F in a water bath.
Then mix the chemicals in the order shown, and be sure each is completely dissolved before adding the next.

Solution B
Water....................................750ml
Sodium Sulfite.......................4.5g
Sodium Carbonate................2.3g
Water to.................................1 liter

Add 25ml Solution A to 250ml Solution B, then add water to make 1 liter of working solution.

I used this for microfilm types a few years back, .It gives higher EI than POTA but not as high as the Spur developers.

Pixophrenic, again I am sorry for the slow reply. Same excuse. I am sharing this with teenagers using net-flix.
I read about Meritol (PPD +?) but this image was before I'd heard of it.
The pH did not change with the Rodinal/Hc-110 mix after use.
Thanks for the reference to Jean Fage - completely new to me - my first reaction was D-23 then a P~Q to follow. Not the same as but reminiscent of Thornton's advice to get a lower contrast.
Thanks again.

Thank you very much, Alan. I was thinking along the lines of 3 solutions, phenidone separately, hydroquinone with bisulfite, and carbonate. This saves me quite some time.

Alan, When you posted the formula above, I did not take a close look and now that I decided to try it, it looks peculiar. Besides, I am wondering what your development time and temperature would have been. The peculiarity of this formula as compared to the formula posted here by Gerald Koch in a related thread (and that I tested to work with several films) is that when I recalculate the working concentrations, it appears that in TEA-based solution A, which is 40X concentrated, the PQ ratio is the same (6.88), however, the working concentrations of phenidone and HQ are exactly 10X less than in the one posted by Gerald. Also, the concentrations in solution B, which is 4X concentrated, are 4X <less> than in the link I posted, so it is actually not a concentrate. A solution with strength approximating the H&W Control as posted by Gerald would be obtained when 250 ml of TEA solution A is mixed with 750 ml of solution B. This would give 25% final TEA concentration, which is alkaline enough (10% TEA has a pH of 10.6, according to Jacobsons) and sodium carbonate would have been superfluos. However, in the way that you presented it,the development time should be rather long, and it may still work as expected (soft). Do I miss something here? It appears that Hoskins may have experimented with dilutions of H&W Control as a starting point, but have arrived at what appears a different recipe. Could you tell me where you copied this formula from? Thank you.

The formula I gave in post 30 is a correct copy of what Tom wrote and is what I used.
I have a print out of a deleted thread.
The working solution concentrations of phenidone and hydroquinone in the linked H&W Control and in Tom's TEA version are closely identical.
Tom seems to have cut down the carbonate and sulfite but TEA is alkaline and a silver solvent IIRC.
My times in the post 30 working solution at 20C:
Rollei ATP-1 EI 25 10min, Copex Rapid EI 25 12 min, CMS 20 EI 12 9min.
The pH of the working solution ~9.5.

Thank you very much, Alan. I see now where I goofed, I did not notice that the TEA part is for 100 ml, so the concentration should be multiplied by 10. The link is also very useful, its text explains why it is no surprise that a repackaged former surveillance film Aviphot aka Rollei Retro 80S behaves so well in H&W Control. The pH of this developer, however, is somewhat of a mystery to me, as it is supposed to be 10.4 or above for maximum "subadditivity" of phenidone. Presumbaly this was explained somewhere in Grafkides' book, but I do not have it on hand.

Dark Days is entrancing. Full marks. But I do have to ask if the inherent contrast of the film enhances the brooding sky or even makes it such. The second one, tho mundane, is a much better example of the film when under control.by suitable developers. Not being picky, merely saying that if my whole roll turned out like 'Diamant' I would be well pleased.

Well, I really like it in Caffenol-C-H (rs).
Rodinal 1+50 also worked well me thinks.

Yes - realy nice shots.
But I would use Retro80s in two directions.Because there is a niche Witz a wide spred of other emulsions.
1) as IR Film
2) as High Resolution film

therfore - to me Rodinal is not the best developer.

Notice : In both cases ( IR and HR use )
E.I. ISO 40 is recomanded.
AND don't forget witch some metol based developers you probably will lost
1 stop.
So you should use this film as a ISO 20 film - but with doing this you get real
"High Resolution"

Well, the Retro 80s with its extended red sensibility is especially suited for taking it out without filters, yellow especially, so naturally, skies and such are the ideal sujet for it I think.
Then, when scanning or printing, one can just push the contrast up a litte and voilá: dramatic skies.
Since I use a great variety of films I almost always use Caffenol, I only found one film to this day that does not work in it, and that is Foma Retropan 320.
Massive grain!
