Superfine grain film developer

Discussion in 'Black and White' started by jay_de_fehr, Jan 14, 2011.

  1. I've been playing with this formula for a few years, on and off, refining and tweaking here and there, and now it has become my primary developer for all films and formats. The advantage of superfine grain for small formats is obvious, but the advantages for larger formats might be less so. In short, improved scanning benefits any format that is scanned, and those benefits also apply to optical enlarging. Halcyon produces negatives of very high resolution, with extremely fine grain, but best of all, very fine gradation. TMY-2 developed in Halcyon is a dream combination, but it works well with all the films I've tested. Halcyon gives normal development times and full film speed, but tolerates overexposure better than underexposure. As with all superfine grain developers, there is a risk of dichroic fog, so fresh fix should be used as a preventative measure. Halcyon makes possible high enlargement factors without compromising image quality. While the superfine grain is the most obvious characteristic, it is the total image quality package that makes Halcyon my primary developer.


    DH2O (distilled water) 750ml
    PPD (paraphenylenediamine) 7g
    Sodium Sulfite 50g
    Salycylic acid .5g
    Ascorbic acid 3.5g
    DH2O to 1 liter

    Develop TMY-2 7:30, 70F, IA


    DH2O 750ml
    PPD 10g
    Sodium sulfite 50g
    Salycilic acid .6g
    Ascorbic acid 5g
    Triethanolamine 10ml
    DH2O to 1 liter

    Replenish by bleed method, 25-50ml/ roll or equivalent

    PPD is toxic, so use appropriate precautions.
  2. How would TMY compare, with this process, with say Tech Pan/Technidol as far as grain goes? Have you used any other films with this process? Sounds awesome!
  3. Jay, Aren't you the mad chemist<g>? So PPD is not known to be high accutance; a) are you equating "very high resolution" to high accutance, b) if so, what part of the formula do you attribute that to? Also, does this work for slow films? ISO 25 range? Did you ever test for a target pH for the developer? And finally, did you compare it to something like Silvergrain's formula for DS-12? It would be fun to do some testing of your forumula, but PPD and I don't get along well<g>. Thanks for publishing this Jay.
  4. Shawn,
    TMY-2 is not as fine grained as Tech Pan, even developed in Halcyon, but the grain is invisible up to about 8X enlargement, even with one's nose to the print. That equates roughly to Tmax 100 developed in Xtol, which is very fine, indeed.
    I don't equate resolution to acutance. Resolution is defined as the ability to resolve very fine detail, with the standard measurement being made in line pairs per millimeter. Acutance is a subjective appearance of sharpness, and in some ways is opposed to resolution. High resolution requires fine grain, while sharpness can appear greater with an increase in graininess. Acutance is more directly related to prints, while resolution can be measured in a negative, or a scan of a negative. Grain interferes with scanning, and does not confer the same increase in apparent sharpness it can to a print. So, for negatives to be scanned, resolution is more important than acutance.
    PPD and ascorbic acid are superadditive, and make an excellent developer pair, giving superfine grain (PPD), high resolution, due to the surface development properties of ascorbic acid, full film speed, and excellent gradation.
    The pH of Halcyon is around 7.8-8.0. Halcyon is not very similar to DS12, despite sharing some ingredients. DS12 is an acutance developer using very small quantities of developing agent in a dilute solution of high pH value. I borrowed from Suzuki the idea to preserve the ascorbic acid with salicylic acid, which seems to work very well.
    The slowest film I've tested with Halcyon is Pan F+, which works great, and the finest graned film I've tested is Acros, which also works great, so I would expect to get excellent results with an ISO 25 film.
    PPD is toxic, which is one reason its use was discontinued in favor of less toxic agents like metol and hydroquinone, which have themselves been replaced by phenidone and ascorbic acid in many modern commercial formulas, but no commercial formula produces results similar to Halcyon. Anther reason PPD fell out of favor was the development of finer grained films, and the fact that most PPD formulas imposed a speed loss of one to three stops. In a way, PPD and ascorbic acid were separated by history, and I know of no other formula that uses the pairing. I use safe lab practices in my dark room, and I'm confident m exposure to PPD is well below the safe minimum. I don't encourage anyone to use PPD who doesn't take safe practices seriously.
  5. Oh, I see what you're doing with the salycilic acid. That's brilliant. Are you going to pre-package the formula? Any particular reason you call it Halcyon? Mysticism/Mythical basis?
  6. Questions about this developer:
    Does it provide normal contrast? Any scanned examples yet?
    Keeping properties once made?
    Is PPD easy to buy and is it inexpensive?
    Does PPD store easily?
    "Develop TMY-2 7:30, 70F, IA" < I know IA refers to agitation method but could you be more specific?
    Thanks a lot. This sounds very interesting.
    = Tom
  7. Is it possible to replace the PPD to OPD which is less toxid and have less stains.
  8. Michael,
    Halcyon is rich in metaphor and associations for me.
    Yes, Halcyon provides a normal range of contrasts, and is suitable for expansion and contraction development. Keeping properties are similar to Xtol, or better. PPD can be purchased from Photographers Formulary for $24/100g, and keeps well on the shelf. IA = Intermittent Agitation, 10 seconds/minute, normal inversion agitation.
    OPD is less effective than PPD, and costs film speed. Halcyon doesn't stain.
  9. Photographers Formulary do not ship paraphenylenediamine outside the US.
    Is it worth trying CD4 color developing agent in its place? Use the same weight?
  10. Alan,
    I have no idea. I don't think any of the alternatives to PPD are as effective. I wouldn't know where to begin suggesting a substitution rate, or what effects a substitution might have on the resulting developer's characteristics.
  11. Thanks Jay, and keep of the great work.
    Your website says you reside in Idaho. What a lovely area with some many great photo ops. - you are very fortunate. Hope the winter has been a good one for you. Take care.
    - Tom
  12. Thanks, Tom. This has been the best winter of my life, and I hope the same for you.
    Be well
  13. Jay:
    Been following your posts regarding your home brew developers for quite some time now. Do you have any idea how this "superfine" developer compares with Microdol-X? I have been using Microdol-X at 1:2 and 1:3 for some time now and have been happy with the results but I also like to experiment a little also.
  14. Hi Jeff,
    Halcyon gives much finer grain than Microdol-X stock, and better film speed. Microdol-X film speed gets better with dilution, but grain gets coarser, too. Evaluating grain in prints is very difficult with Halcyon, because of the enormous enlargement factors required to see it, even with small formats and fast films. I can't find grain on which to focus with my grain focus scope. Scanning at high resolution can be useful, but the accuracy relative to printing is questionable.
  15. Thank you, Jay for that. Quite ground breaking. I have a curly question. How do you think it might go with Imagelink-HQ?
    I am trying to tame this film and have heard that C-41 developers are useful for microfilm to obtain pictorial quality. My PPD is 50+ years old and quite black but I remember that the results were soft but not quite sharp, using Pan-X and similar. I am into Minolta 16mm here.
    I could try CD-4 but will order in from Canada some PPD if necessary. I am in Australia. Basically looking for some words of encouragement. :)
    I was unaware that VitC and PPD were superadditive but then, who has tried it before?
    My tiny sample of salicylic acid has vanished - it must vaporise (can't remember the correct word but will think of it tomorrow) if not closed tightly. I could maybe try aspirin.
    Any hints much appreciated
  16. Jay, as I can understand you use PPD base? or some salt of PPD?
  17. Murray,
    Sorry for the delayed reply, I didn't see a notification in my inbox. Coincidentally, I've been shooting a lot of Imagelink HQ lately, and the best developer I've used for it is the following:
    Propylene Glycol (PG) 70ml
    Phenidone 7g
    Ascorbic acid 1g
    PG to 100ml
    The alkali can be adjusted for the contrast desired. Good results can be obtained from the following, highest contrast to lowest, diluted 1:1:100* with the A solution and water to make a working solution:
    Sodium carbonate 10% solution
    Sodium metaborate 10% solution
    TEA (triethanolamine) 99%
    Borax 10% solution
    *Sodium sulfite 10% solution (use for diluting A solution 1:100)
    The attached image was made with Imagelink HQ EI 25, developed in the above developer diluted 1:1:100 with 10% sodium carbonate solution, 6min, 70F, agitated 10 sec/minute.
    The PPD I use is: Paraphenylene diamine (1,4-Benzenediamine,1,4- Diaminobenzene) Flakes, CAS # 106-50-3, C6H6N2
    I hope this helps. I just developed a roll of 35mm TMY exposed in an adorable little Chinon Bellami compact camera, in a liter of Halcyon I've been using/replenishing since September and the negs are drying now. They look pretty good! I'll scan a frame or two and post something later.
  18. Jay, Murray,
    formula of PQ developer for Imagelink HQ reminded me some other receipt for high-contrast technical film.
    Phenidone 1g
    Hydroquinone 2g
    Sodium Sulfite 30g
    Sodium Carbonate 10g
    KBr 1g
    Water 1l
    I found this formula in patent US4205124 "Low gamma photographic developer". I was modify it with added some KBr. This is very active developer. I'm need only 2min for developing PolypanF 50 with push +1 with acceptable contrast
    I haven't PPD base, only PPD.2Cl. no problem to make PPD base: 18.1g of PPD.2Cl + 8g of NaOH = 10.6g of PPD base. so I will try this receipt, because have very good experience with other PPD-based developer - Meritol-Metol. HP5+@400 15min produce very fine negatives with grain and contrast less than in D76 stock
  19. Wow! Thanks Jay and Andre. The sample, Jay, looks great. Reminds me of the Camaro I just sold.
    I have been struggling for ages to get somehting acceptible and the best so far has been a D-76-like 1:10 with the pH pulled down to about 8. Only problem is repeatability. Test charts look excellent but real life strips are just not right at all. My exposure guestimates could well be my downfall.
    These 2 will give me encouragement to continue the battle.
    I am using 16mm and have 600' of the stuff. :-(
    The supplier of chems in Canada has gone out of the supply side and PPD is off the menu for me until I can find another. Possibly European.
    Thanks again guys.
  20. This is really interesting developer. I finally pushed myself to order ascorbic and salicyl acid and results are amazing. PPD as a developing agent itself has tendency to let grain grow to enormous sizes in lights, but with ascorbic acid are results virtually grainless even with 3-stop overexposure.
    Thank you Jay for bringing this formula to light.
  21. Hi karol,
    I'm glad you're getting good results. I like this developer very much. Thanks for your kind words.
  22. I've used ascorbates with CD-2 (ppd derivative before) also combined with phenidone.
    I've stumbled on something which may trump even ascorbic acid which I do not believe has ever been used before.

  24. Well, Dan, don't keep us all in suspense; what is this mystery ingredient?
  25. Bin holding my breath!
  26. Watching and reading silently. Very informative discussion. Special thanks to you Jay.
  27. Very well, but my response will take a few days at least, I want to write up an article or blog post first rather than suddenly disclosing on a forum.
  28. Thanks, Dan. Keep us posted where we may see it. Thanks again.
  29. Okay, I've made a basic post on it at

    I did not wan't to disclose anything until I had something awesome to show with lots of info and pics, however I didn't want to delay much longer either. Article is pretty basic right now

  31. That's interesting, Dan. I'm sure you're aware there are many compounds that darken film but don't make satisfactory film developers. I'm curious about the interesting properties you hint at. I'd like to know if it keeps better in solution and/or preserves better than ascorbates, and if it is soluble in TEA or glycol. That alone would be worth investigating, even if it had no developing action. I'll certainly look into it. Thanks for the tip!
  32. It actually has interactions with Vitamin C, it may even be super-additive with it - the other way round to normal, this compound may regenerate Vitamin C. The amount of this compound in certain organic matter is far higher than the range of polyphenols found in most things.
    The chemical structure has numerous hydroxy groups on rings.. it appears like a powerful developing agent.
    The solubility is low in most solvents, water, ethanol, even DMSO I think, not sure about TEA and glycol. But it has high solubility in bases iirc.
    The data that I -can- find, suggests 50g/L of the compound is soluble in 1M of NaOH (39.997g/L NaOH)
  33. If quercetin is more a more potent preservative/developer than ascorbates, it doesn't need to be terribly soluble for many purposes. Ascorbates hydrolyze in alkali solutions, and require a preservative of their own, such as the salicylic acid in Halcyon. If Quercetin keeps in alkali, it might offer advantages over ascorbates in some applications. The possible additivity with ascorbates is interesting, but I'm not sure how one could determine which compound regenerates which, if any.
  34. Gee! Look at all those hydroxyl radicals! In all the right places, too.
    Interesting that the name comes from oak trees as Pyrogallol is originally from oak galls.
    I tried some red onion on on a piece of film and nothing happened until I wet my finger with TEA and water and added that. Then it worked. Obviously needs alkali to work as a developing agent, like most. Don't know if there is s commercial supply of the stuff. Wikipedia was pretty vague about a lot of its properties and supply.
    Most interesting. Thank you.
  35. It may be on the EPA or Terror list. LOL
  36. Logically I would think to regenerate oxidised quercetin back again, eg; reduce it back to it's state, it would need a more powerful reducing agent than itself, hence I don't think ascorbate would do that.
    And salicylic acid under goes the acid base reaction to form salicylate :) Aspirin hydrolyses to salicylic acid in strong acids.. however it will also hydrolyse straight to salicylate in a base, so there's an easy source there.
    Murray: I think you can get it in some health supplements. I've seen it on ebay in 500mg tablets.
    I guess one could mash onions into water, boil it (another something I read states it doesn't damage/decompose etc at cooking temperatures) and vacuum filter it to wash out all the water soluble compounds, then mix whats left with a base, filter that, titrate the base to neutral pH.. hopefully the quercetin should precipitate out if there's enough of it.
  37. I finally got around to sourcing some quercetin (found it my co-op), though far from pure. I found a supplement called Quercetin Bioflavonoid Complex, in 500mg capsules that contain:
    Quercetin 235mg
    Citrus bioflavonoid (from citrus peels) 235mg
    Bromelain 1000 GDU (from pineaplle stems) 45mg
    Rutin 45mg
    I made a developer by dissolving 3 capsules worth of powder, which amounted to appx 2g of powder, of which appx 0.7g is quercetin, along with 10g of Arm and Hammer laundry detergent, which is said to contain sodium carbonate and some wetting agents, into 300ml of water at around 80F. I developed a short strip of 35mm Ilford Pan F+ for 10 minutes with 10 seconds agitation/minute, then fixed in Ilford rapid fixer.
    The quercetin complex is not very soluble in water, or alkaline solutions, though it's not clear which parts of the complex are insoluble. The resulting solution is bright yellow and yields a yellow-brown stain on the film. The developer as made above also produced some fogging, not surprising considering the alkali content and absence of restrainer, though not enough to cause problems in printing or scanning. The used developer is darker yellow-brown, which is not unexpected since there is no preservative of any kind in the developer. I will have to do more formal testing to determine if the stain is proportional, or just a general dye. Overall, I'm quite impressed with this new developing agent, and I think it's worth pursuing. I don't have much on hand to work with, but I'll try adding some ascorbic acid and see how that affects the developer. I wish I had my sensitometer and densitometer for this testing, but instead I'm just kitchen-sinking it. The attached was shot outside my window in the rain, so the light was very flat. Exposure was EI 50.
  38. If focus was on there is edge dissolving out the ying yang there.
  39. Depends on the scanning among other things, but in any case good so far.
  40. Yes, focus was not good. I was in a hurry, as it was raining on me, but I think there is potential.
  41. Always potential . I started with Dektol for film only..... 2012 may make all of us famous again. LOL
  42. Thanks, Jay. I went thru the local health food shops but couldn't find quercetin, nor did anyone know of it.
    I see it on-line so that would be my only access.
    Looks like it might be a stainer? HQ and Pyro have a similar structure so that comes as no surprise. Water solubility - maybe some isopropyl alcohol or good ol' glycol for a concentrate. Just think of all the fun you're going to have! :)
  43. Hi Murray,
    I think I'll keep looking for a source of pure quercetin- most likely online. It's hard to say much about quercetin's properties as a developer at this point. It seems to require a high pH environment to work, but it doesn't seem to exaggerate grain. I'm interested in it's possibilities in combination with other developers, like ascorbic acid, or pyro/ catechol, etc. The only developers I have on hand at the moment are quercetin, ascorbic acid, and p-aminophenol. It would be a lot more fun if I had my tools.
  44. Hi, Jay. I didn't realise you were out of your environment. Pretty cool to do anything at all, I'd say.
    I have ordered some quercetin off the 'net and will eat the stuff if I can't do something photographic with it! Interesting that you expect it to need a high pH as the pyrogallol works down quite low. Perhaps I'll give it a 'go' with metol.
    I'm up to my eyeballs with work at the moment so it's not going to be a short story.
  45. Murray,
    Don't take anything I say as gospel; I'm just fumbling around in the dark. I couldn't get the quercetin to do anything with borax, but it might be the case that I wasn't using enough of the developer. It seems to act more like catechol than pyrogallol, but like I said, I'm just guessing at this point. I hope your quercetin is more pure than mine. I think I'll go by Glazer's and pick up a few essentials, like sodium sulfite/ metabisulfite, KBr, maybe some more developing agents to try some pairings. Good luck with your work, and your experiments, and do keep us posted.
  46. I made another test with Kodak Imagelink HQ film and the following developer:
    Quercetin capsules 3
    ascorbic acid 0.7g
    washing soda 10g
    water 300ml
    Development: 10:00/ 80F/ agitate 10 seconds/3:00
    Result: Grossly overdeveloped negatives with little/no stain. Negatives appear to be quite sharp, and gradation is not terrible, despite the high contrast material and over development. Due to the poor solubility of quercetin, I think it's best suited for use as a secondary developer, and that's the path I plan to follow in future experiments, beginning with ascorbic acid, but following with catechol as soon as I can get some. I want to try substituting quercetin for the ascorbic acid in Hypercat II, but I really wish I could find some pure quercetin.
  47. Interesting results.
    This patent notes that Quercetin is almost insoluble in water (elsewhere it is stated sparingly soluble in aqueous buffers),but Quercetin Chalcone dissolves 20% in distilled water:
    Thorne Research Quercenase pill supplement contains:
    250mg soluble Quercetin and 100mg Bromelain per capsule.
    It might be of interest if the Quercetin wont dissolve.
    I wonder if it would be superadditive with phenidone.
  48. Thanks, Alan!
    Solubility is indeed sparing, in my very limited experience. I'll look for the chalcone variant. I think I'll contact Mike Jacobson at Artcraft Chemicals and see if he can find the pure stuff, sans bromelain. I don't have any phenidone on hand, but I might be able to get my hands on some metol. I'll keep you posted.
  49. Quercetone is reported to be Quercetin Chalcone, each capsule containing 250mg and a small amount fillers, magnesium citrate,silicon dioxide.It would be better than Quercenase I mentioned above.
  50. I must say the IL-HQ is impressive from the tonality point of view, Jay. But then you are used to getting it pretty darn good! AN EI of 40 is a distinct advantage, too.
    No sign of the capsules yet. May take some days. My first action will be to see if anything I have here dissolves it better.
  51. Murray,
    The image I posted was the best of the bunch, from a gradation standpoint, though not necessarily the sharpest. Overall, gradation was very coarse. I'll attach another example. I'm very curious about the quercetone. I hope your caps turn up.
  52. More work on Quercetin.By mistake I ordered Quercenase capsules instead of Quercetone.
    Each capsule of Quercenase contains 250mg Quercetin Chalcone and 100mg Bromelain.I am assuming the Bromelain has no detectable effect in my experiments.
    First this developer was made:
    Quercenase..........................6 capsules(the contents can be tipped out)
    Sodium Sulfite.......................2 teaspoons
    Washing Soda Crystals.........3 teaspoons
    Water to................................600ml
    Mixture was heated to 50C with stirring and filtered through cotton wool.There was a lot of residue and the developer was dark brown like ancient Rodinal.
    T-Max 3200(TMZ) was developed in this for 27m 68F .The resultant negatives were very thin,no use.
    To the above mix I added:
    Phenidone..............................0.2mg (approx)
    Again TMZ was developed 27m 68F. The result was quite a good set of negatives, see pic below.
    Finally I repeated the test leaving out the Quercenase to check that the phenidone alone was not giving the good negatives. Without the Quercenase the negatives were very thin.
    The tests suggest that Phenidone is the primary developing agent and the Quercetin Chalcone ingredient of Quercenase regenerates it, they are superadditive at this pH~11.5.
  53. Would not the Bromelain act as a restrainer?
  54. I see an enzyme blocker.
  55. Alan,
    How do you isolate the contribution of the quercetin in the QP developer? Did you try the same developer without the quercetin? Just curious.
    Before I wasted too much time with quercetin, I wanted to satisfy myself that it was indeed a developer, so my first tests were just quercetin and sodium carbonate. When I got acceptable results, I had a baseline from which to assess the effects of any additional agents; in my case, ascorbic acid. I think it's possible the phenidone in your developer is capable of producing your results without the help of quercetin. I'd want to rule that out by running another test with phenidone alone. Isn't this stuff fun?!
  56. Jay Um Yes as I am now playing with Aspirin as a developer. It works but is slow but now mixing some Ascorbic acid it gets faster. It though also is acting as a restrainer in Caffenol and making finer grain without base fog in the vein of Kbr. Just finer grain.
    Some day in the future when there is no developers sold on the internet, MacGyver may be all we have left. :-(
    Fun though it is.
  57. I wish I had ordered the right stuff Quercetone but at about $30 a time will carry on with Quercenase for now.
    Please see the second last paragraph of my post, I did run a test with phenidone and no Quercenase and it produced only very thin negs.
    However the test is worth repeating at this early stage ,it is wanted to know if Quercetin Chalcone is a regenerator like hydroquinone, ascorbic acid, pyrocatechol or a primary developing agent like phenidone, metol.
    I might try make a staining developer with it since it seems to need high pH.
  58. Alan,
    Sorry I missed the second paragraph. Quercetin is actually a heavy stainer. I thought of pairing it with catechol, but that will have to wait until I get some more soluble quercetin, preferably without a lot of additives. I would try replacing the ascorbic acid with quercetin in Hypercat II, weight for weight, to start. But, since one of the roles of the ascorbic acid in Hypercat II is to control stain, it's not clear how the substitution might affect the resulting developer, but that's what experiment's are for.
  59. Alchemist are some of my favorite people... :)
  60. Larry: Aspirin in Strong base or Acid will give the salicylate salt or salicylic acid, or salicylic acid itself (strong acid), which of course you can use to protect developers.
  61. I found it though will develop with a Base... ,,, Acts though as a restrainer in the iodine sodium class at times too.... Though remember I am the guy who used urine as a developer.. :)
  62. Please post a 4,000 dpi (or higher) scan of TMY or TMX.
    I would like to see the results and compare it against my developers.
  63. To whom are you talking to Mauro?
  64. Formula correction:
    In my post giving the formula used it should read :
    Phenidone.....................0.2g (approx) and not 0.2 mg.
    I only did about 3hrs work on this, it is too early to test as a good formula is not yet established.
  65. Lately I've been thinking about biological developers. Theoretically, it should be possible to genetically engineer a bacteria, like e-coli, to convert sugar to a developing agent, in solution. If film had a future, this is the course I would pursue.
  66. I meant the question for Jay. I would like to see a scan or maybe look at a spare negative if you can mail me one.
  67. Mauro,
    To which of my developers do you refer? If you're referring to the quercetin developers, those are just experiments, not really developers. If you refer to Halcyon, I might be able to get a good scan of one of my negatives. A friend of mine has an Imacon, and has offered to scan a few negs for me, and I could include one developed in Halcyon. My own scanner is an Epson 4490, and not much of anything can be determined by scans from it.
    What are your developers?
  68. Halcyon.
    I mainly use Xtol with a few touch ups. I get no grain at 4,000 dpi from TMAX and very smal with TMY-2.
    I was wondering if you thought Halcyon produces finer results than Xtol and how did you determine that.
  69. Yes, Halcyon produces finer grain than Xtol. I determined so with lots of comparisons. TMX and TMY-2 are not the best films for grain comparisons, because they're both very fine grained. Tri-X is better, HP5+ is better still, and Foma 400 is even better. The difference in grain is quite apparent, even in moderate sized prints.
  70. TMY2 would still be easy to evaluate with my Coolscan and microscope.
    Could I email you my address in the hope of getting a piece of film for evaluation?
    If not, can I send you a roll to develop? I would take two rolls and shoot them in parallel and develop one myself and send you the other. You can then mail it back to me and I will scan them together with the same settings.
  71. Why are the ImageLink pictures posted here so greyish?
  72. Mauro,
    There a re a few problems with your proposal. One, I'm at work in Alaska, and so I don't have access to my negatives, and two, I don't have any Halcyon since I left my dark room in Idaho for an apartment in Seattle. When I get home, I'll try to find a negative developed in Halcyon, and ask my friend with an Imacon to scan it for me, and post the results.
    Getting a low contrast image from Imagelink is much more challenging than getting a high contrast image. Your flowers image looks like what I'd expect (blown highlights and empty shadows) from Imagelink in standard developers. I posted my image as an example to show it's possible to get normal pictorial contrast from Imagelink film. I'm not sure why the image looks "greyish" to you, as there is a full range of tones from black to white, with a lot of tones in-between, which is what I want for a pictorial rendering.
  73. I sure don't see grayish in that Christer. Maybe time to check your monitor.
