B&w slide tried and true process

  1. I just wanna share with the community my process, hoping it will turn useful to
    anyone...

    Kodak T-Max 100 (@100)

    First development: Tetenal Eukobrom 1+5 (42ml) for 11 minutes at 20?C, add
    125ml of a 2% di sodium hypo (equalling 2,5g of the same chemical specimen in
    250ml), 1 inversion of 5 seconds every 15 seconds; diluition guideline: 125ml →
    167ml → 250ml; start with 125ml of a 2% sodium hypo, then add 42 ml of developer
    (up to 167ml) then add water up to 250ml;

    Washing: modified Ilford method 5/10/20/20 with tap water adding EDTA 2g/l;

    Bleaching: 4g potassium permanganate in 1000ml of pure distilled water (stock
    solution A), 40g sodium bisulfate in 1000ml of pure distilled water (stock
    solution B); take 62ml from stock A and add to it 125ml of stock B, then top it
    off to 250ml with pure distilled water; 5 minutes using constant agitation; it's
    paramount to prepare this solution just before use;

    Washing: modified Ilford method 5/10/20/20 with tap water adding EDTA 2g/l;

    Clearing: 25g sodium metabisulphite in 1000ml of pure distilled water, 2 minutes
    using 1 inversion of 5 seconds every 15 seconds;

    Washing: modified Ilford method 5/10/20/20 with tap water adding EDTA 2g/l;

    II? exposure: at the distance of 10 cm from a fluorescent bulb exposing for 1
    minute each side of the spiral, mantaining it on the tank full of pure distilled
    water;

    II? development: Tetenal Eukobrom 1+9 (25ml) for 6 minutes at 20?C (for other
    temperatures check the Ilford Conversion Table), 1 inversion of 5 seconds every
    15 seconds;
    Washing: modified Ilford method 5/10/20/20 with tap water adding EDTA 2g/l;

    Fixing: add 5m of Tetenal Härter to 30ml of Agfa Agefix and then top it off to
    250ml; treat for 5 minutes, 1 inversion of 5 seconds every 15 seconds;

    Washing: modified Ilford method 5/10/20/20 with tap water adding EDTA 2g/l;

    Washing: modified Ilford method 5/10/20/20 with tap water adding EDTA 2g/l;

    Photo-flo: add 0,25ml of Agfa Agepon to 250ml of pure distilled water;

    Hang to dry in a dust free environment (I use a home made film dryer using a
    Toyota air intake filter and a hair dryer under a big plastic bag)


    You can alternatively swap the Eukobrom with any other paper developer you have
    handy, changing accordingly the development time through trials...
     
  2. Glad this is working, Alessandro. I'm going to link to this thread from my site.

    The EDTA probably isn't necessary unless you have hard water.
     
  3. Hi Jordan,
    glad to hear from you!

    Yes, my tap water is very hard, it's 32 ?F or around that figure, with a pH of 7,5-8.

    I'm just attaching some pics just to show...
     
  4. Another sample
     
  5. The 2% hypo solution at the beginning is in reality a 20% solution.
     
  6. Correction to my last post: it's a 2% solution meaning 20g hypo in 1 litre of water.
