Fuji Acros 100 and Diafine Developer – Part 2

Finally part 2! Here are some sample images made on my M7 Leica and my Rollei 2.8 (F – 1960) using Fuji Acros at an EI of 160.

The two square images of course were shot with the Rollei (120mm) and the hand and zipper image was made with my Leica M7. Full size the Rollei images are 18″ x 18″ (142MB, 16 Bit, Grayscale, 120mm Negative, 3200 dpi scan) and the hand and zipper image is 16″x 24″ (160MB, 16 Bit, Grayscale, 35mm Negative, 6300 dpi scan). The detail crop of the zipper represents approx a 3″x4″ section of the larger 16″x24″ print…amazing!

Here is how I processed it…

Fuji Acros 100…EI 160

  • Diafine Developer at 68-72 F
  • Part A 4.5 minutes (two inversions every minute…gentle.)
  • Part B 4.5 minutes (two inversions every minute…gentle.)
  • Water Stop 1 minute Fill and Dump (68-72 F)
  • Fix Kodak Rapid (5 minutes)
  • Wash 1 minute running water (68-72 F)
  • Perma Wash 1 minute constant agitation
  • Wash 5 minutes (65-75 F)
  • LFN
  • Dry

For more information on the process and testing conducted please listen to the audioblog link below….

TIP– When your developer starts to get dirty…say after 30 plus rolls just run it through a coffee filter to “clean” it…use a different filter of course for each solution.

  1. I love Acros to death! I expose it at its native speed of 100 and process it in two developers successfully:

    Microdol-X: 75 degrees, 1:3, for 18 minutes when I need to control excessive highlights

    ID-11: 68 degrees, no dilution, 6:45 minutes for standard shooting

    In both cases, I get astonishing tonality, sharpness, and detail with my Leica R8 and M6 TTL cameras and related lenses with both natural light and with my Metz flashes. I used to use only Delta 100, but I have discovered that Across 100 is just as forgiving in all exposure environments and I like its appearance on prints I make in my darkroom more than I do with Delta 100.

    Am new to diafine and Acros 100 but am excited by the combination – am in the process of shooting test roll at 200 and your article and examples are very useful – thanks, Jeff

    Just finished a test acros 100 @ 200, 3.5 min A and same B, 70degrees – I think it needs more speed – highlights way overexposed (about 2 stops??) – more tests at 400 tomarrow though I am impressed as it is.

  4. Stephen, I really appreciate your tutorials regarding Dianfine and I am starting to use it with reasonable results. I recall a post you made saying you were going to do one on the scanning peocess and contrast adjustment that you make in post. Have you posted that and I missed it? I would really like to learn more about your technique. Thanks!

    Stephen,

    Thanks for all the information you’ve provided on Diafine/Acros. I’ve managed to develop few rolls of Acros 100 (and I really like it) but one or two had few frames with silvery spots on them (when inverted – that is, the circular spots looked black on the negative itself). I’m guessing under-agitation but which part, A or B?

    And what happens if I over-agitate? Part A vs Part B.

    Thanks a bunch!

    Hi

    I started doing b/w analog again one year ago (after a short 20-year break(!)) Pinhole first and now i’m using a used Hassi500 too. Its simply more fun than doing digital.

    Combination, almost Efke 25,50,100 & FP4/HP5 with rodinal. But i want to try another combo now.

    I like to experiment more with the picture itself than with the developing process, so Diafine could be a choice for me.

    The article is very helpful. I ordered some rolls Acros 100 and Diafine today.

    Can you say something in general about agitation / solution B?

    Thanks!
