B&w slide tried and true process


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 concentrate (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); mix in a separate container 62ml from stock A and 125ml from 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)
