fotohuis Posted August 11, 2015 Share #21 Posted August 11, 2015 Advertisement (gone after registration) Retropan 320 Soft E.I. 640 in Diafine 2-bath. You can only "hope" for a speed enhancing effect of 2/3F stop with this combo. Summer in Holland is also a bit warmer now: 25,5C film development. In fact not a problem for Diafine which should be in the range of 21-28C.Unfortunately not a good combination. There is hardly any speed increase, so the end result is an underexposed negative and loosing 3 zones in the highlights.Measurement in the test chart and densitometer are only confirming this. NOT recommended!A pity for my last original Diafine BKA 2x950ml/1 Quart.I have to try something else for more speed for this Retropan 320 soft Foma film. The camera doesn't help: This time my Leica M7 + Elmarit F/2,8-21mm. Link to post Share on other sites More sharing options...

chris_livsey Posted August 12, 2015 Share #22 Posted August 12, 2015 Some more from the first test roll: Highlight of the sun on the metal band seems to have produced some halation, but not burnt out, a bit strange this. Less extreme light and the grain is less intrusive here. This Himalayan Balsam in deep shade shows off the "soft" part of the name while retaining nice tone separation.

fotohuis Posted August 13, 2015 Share #23 Posted August 13, 2015 At least the grain with Xtol is very moderate. Less then in Supergrain, HC-110 or Diafine. My next step will be Retropan 320 E.I. 640 in Microphen. Another speed enhancing type developer. Maybe more luck. Link to post Share on other sites More sharing options...
chris_livsey Posted August 13, 2015 Share #24 Posted August 13, 2015 Pyrocat HD 5 min pre-soak then 15mins semi stand @72F Leica M2 C Sonnar 50mm f1.5 (keeping the same lens for the time being) No hint of a dye coming off in the 5min pre-soak. Takes the stain very well. Larger files on the Flickr as below in sig. and new Flickr group: https://www.flickr.com/groups/2835476@N25/ The old Preston Royal Infirmary (UK) Evenly lit, no extremes, nice and sharp with the Pyrocat HD as Semi stand but "here comes the grain again" (Apologies to the Eurythmics).

fotohuis Posted August 13, 2015 Share #25 Posted August 13, 2015 Grain, yes but a very regular grain and a tack sharp result with the Pyrocat-HD (from Sandy King). Is this an E.I. 320 result? Link to post Share on other sites More sharing options...
chris_livsey Posted August 13, 2015 Share #26 Posted August 13, 2015 Grain, yes but a very regular grain and a tack sharp result with the Pyrocat-HD (from Sandy King). Is this an E.I. 320 result? Indeed Sandy King deserves much praise for this formulation. It is @320, I had made the error of "pixel" peeping, when viewed at normal size the results are very good. I will post some more from that roll soon on the Flickr rather than flooding here. I may try some HC110 next but whenever I use the Pyrocat HD I wonder why I ever change developer. The stock solutions (home brew) are 10 months old now, stored cool and dark, and have no loss of potency, they are clear and colourless, another little experiment.

fotohuis Posted August 13, 2015 Share #27 Posted August 13, 2015 Advertisement (gone after registration) You can keep Pyrocat-HD and Pyrocat-HDC at least 2 years without loss of strenght. Only the ingredients in powder are not very healthful to make. I am offering these developers from Sandy King in my program but they are made in Ukraine under lab conditions, put in liquid and then shipped. Even the pictograms according GHS are made etc. The biggest disadvantage for me is that every film gives another type of staining which is not working well with the Heiland Split Grade system in printing. Of course you have this with almost any other Pyro developer too. But you are right: Pyrocat-HD is in staining type developers one of the best. And this first result in combination with the Retropan 320 is really great! Link to post Share on other sites More sharing options...
chris_livsey Posted August 13, 2015 Share #28 Posted August 13, 2015 I have the advantage of being a pharmacist with access to ventilated fume cupboards etc for making it up, and decent containers to store it in. I can see the printing that way would need work for each film, even visually they vary, as I commented this Retropan does take the stain well, some films look almost "normal" in comparison. I forgot you showed the HC110, i have some Harvey 777 in use but was hesitating to use it for this as there is not much about in Europe and it is not "fair" to test with non standard developers. A friend sends it from Canada as Bluegrass will not export. Link to post Share on other sites More sharing options...
fotohuis Posted August 13, 2015 Share #29 Posted August 13, 2015 Harvey 777 is an ultra fine grain type developer containing para-Phenylene Diamine, stuff staining like hell and very poisoning too. I am offering the (Hans) Windisch W665 instead, using ortho-Phenylene Diamine, less staining and less toxid too. But using these type developers you can start with half box speed. Further for the best result you need some rippening of the developer by a piece of old film before starting.The same is valid for Perceptol or CG-512/Rollei Low Speed, resp. Ilford, Uddo Rafay. 1+0 or 1+1 half box speed. Tomorrow I will do the Microphen test. Link to post Share on other sites More sharing options...
fotohuis Posted August 14, 2015 Share #30 Posted August 14, 2015 Developed in Microphen 1+0 during 12:00 minutes (20C). E.I. 640 and still a lower contrast. The maximum density in the negative is around 1,05 logD. Easy to print but now you have really some grain. Link to post Share on other sites More sharing options...
chris_livsey Posted August 16, 2015 Share #31 Posted August 16, 2015 Another day another developer, I tried FX-28 a formula from Geofrey Crawley commercially available. For time I took a stab in the dark, no pun, well an educated guess based on previous experience, of 8 mins. Seems fine, again rated at iso320. The leaves that are very pale are quite yellow and certainly jump out from the green. This one shows the low contrast nicely I think, and the grain, which doesn't vary much so far although the Pyrocat I think was a tad "tighter": More on the Flickr as usual.

chris_livsey Posted August 17, 2015 Share #32 Posted August 17, 2015 Another day another developer, I tried FX-28 a formula from Geofrey Crawley commercially available. I of course meant to type FX-39 !! Not allowed to edit a post directly now after a certain time apparently. Link to post Share on other sites More sharing options...
fotohuis Posted August 17, 2015 Share #33 Posted August 17, 2015 FX-39 is normally used for modern technology films like Tmax, Delta, Acros films. For most cubical type films you will end with to many grain. Link to post Share on other sites More sharing options...
chris_livsey Posted August 17, 2015 Share #34 Posted August 17, 2015 FX-39 is normally used for modern technology films like Tmax, Delta, Acros films. For most cubical type films you will end with to many grain. The shots I have processed look to have the same grain as with the other developers. Of course that is purely subjective I do not have instruments to measure grain. I used FX-39 as it is an MQ developer which the Foma "Special" developer is.

fotohuis Posted August 17, 2015 Share #35 Posted August 17, 2015 For Geoffery Crawley I tried the FX-37 which is published, FX-39 is not. And the FX-1 which is in fact a modified Beutler developer with a trace of PotassiumIodide. FX-1 is very good for the slow speed Adox/Efke 25-50 single layer type films from Fotokemika. The Efke 25 / Rollei Pan 25 / Adox CHS 25 were doing extremely well in it. It is now three years ago they stopped producing in Croatia. Such a pity. FX developers are not very well known outside the UK. I am sure it has to do with the bad marketing strategy of Paterson in the past. Crawley published a lot in BJP and had good ideas in film development. Link to post Share on other sites More sharing options...
fotohuis Posted August 17, 2015 Share #36 Posted August 17, 2015 I can not resist. I have to show you the result with FX-1 and Efke 25. Such a beautiful combination when optimized. Same dog "Stip" in Winter and the already known famous woman. Yes, I know this is Efke 25/Rollei Pan 25 E.I. 32. in FX-1 1+1+10. Not iso 320 or iso 640.

I am a fan of "straight" Beutler. I have never found an explanation of the tiny amount of potassium Iodie in FX-1, but it works!!

fotohuis Posted August 17, 2015 Share #38 Posted August 17, 2015 Indeed, great example. The test for Retropan 320 Soft is a bit slower now for the last days. It is raining here the last few days cats and dogs, really crappy weather. Not sure if my M7 is a bit water tight. Otherwise my F.S.U. RF cameras Zorki-6, Kiev-4AM or FED-3 can do the test job too.
