    GEVAERT G.33 Soft Developer

    Soft-working film developer with extended shadow detail

    Mixing instructions: Add chemicals in specified sequence.

    Dilution: Use undiluted

    Starting point development time: 8 mins (tray), 14 mins (tank)

    Just mixed a liter tonight, going to try it tomorrow with Arista EDU Ultra 120 in 100 and 400 ASA and try 14 minutes for roll tanks.

    Forgot to add; used .83 g of Sodium Bromide instead of 1g of Potassium Bromide as per substitution table in Anchell's DRCB.

    All films shot at rated ASA/ISO speeds.

    For Arista Edu 100 -- I suggest 14 minutes with 15 sec. agitation per min.

    For Artista Edu 400 and Ilford Pan F 50-- I suggest 12 minutes with 15 sec. agitation per min.

    Kodak TMax 400 -- not recommended

    The effects of extended development depend heavily upon the stock, but tend to work best on slower, old-style emulsions.

    Ilford HP5 -- somewhere in the vicinity of 12 minutes -- YMMV

    Do you have a reference for this?
    I looked in the Gevaert manual and Taylor&Taylor photo lab-index but cannot find such recipe

    Well, I will have to pile through my books again, but I DO know it is posted on the Digital Truth site in their formulas section online.

    I think there is something wrong in the numbering, film developers had numbering 210-230s, paper developers 250-260s. So it maybe 233?
    The only one I've found that is close is G212
    * Water, 125F/52C 750 ml
    * Metol 2 g
    * Sodium Sulfite (anhydrous) 25 g
    * Hydroquinone 1.5 g
    * Sodium Carbonate (monohydrate*) 35 g
    * Potassium Bromide 0.5 g
    * Cold water to make 1L

    Given the amount of Metol, this should be quite vigorous? or am I wrong?

    There is a Gevaert GD-33 formula on page 84 of Morris Germain's Darkroom Handbook and Formulary, published by Ziff-Davis 1940.

    This Gevaert GD-33 formula is identical to the one posted by Kino.

    Thank you, Tom. I knew I wasn't crazy... well at least in that respect...

    I think mine came from a Focal Press book from the Mid to late 30's that I can't lay my hands on again to save my life. It is part of a two volume set; one is "Developing", the other, "Enlarging".
