    Sure, there we got the problem - you give yourself the good stuff while your films have to suffer being bathed in instant coffee? Is this fair? No - no wonder they were underdeveloped... this happens when a film receives no proper treatment and love - just like with kids.

    Next time drink the Instant coffee and treat the APX with Rodinal. Or a decent Arabica.
    Tschüss,

    By using 300 ml you need 2 more tsps of coffee and 1 more tsp of Washing soda
    Also your development time seems very short, I'd give it another 20 minutes.

    I have had the best results with films in the 100 EI range (FP4, JC Classic)

    For 300ml (12 oz)

    3 tsp Washing soda (dissolve this first)
    6 tsp Instant coffee

    Develop for about 30-45 minutes @20C

    Stop/fix/wash as usual

    Thanks! I'll try with a roll of Agfa 100 (any objections?). What about the T-Max or Delta? Does the grain type of these film respond to this?

    I dodn't have good experience with APX400, but APX100 should be fine
    Just note that APX 100 times are usually longer than the rest so 45 min should be fine.
    Try bracketing the roll from 50 to 125 or so and see which one looksbest

    I just got some EFKE 100 and I'll be trying that one soon.

    Baking soda is Na-Hydrogen-Carbonat, gives an pH around 8, sodium carbonat gives around 11-12, depending on concentration.
    Colour? We can always use an airbrush later...
