Comments:  10 -15 gentle complete inversions in the first 30 seconds, then 1 inversion  every 30 seconds for the remaining time.  I process using plastic Paterson tanks.  I meter out the Rodinal in a syringe 3 ml of Rodinal to 300 ml of  68 water.  The resulting negs print wonderfully in my diffusion enlarger.  Using the syringe is important...there is very little difference between 3 ml and 4 ml when you use a beaker to measure.  The single inversion every 30 seconds is important because my highlights blow out if I over agitate.  [Rate film at EI 125 for condenser enlarger.]

Comments:  Agfa 8 is a glycin developer intended for portraits, and it gives superb  mid-tones and a very sharp result.  The grain is similar to what you get with Rodinal.

    Agfa 8:

    Warm Water (125 F or 52 C) -          750.0 ml
    Sodium Sulfite, desiccated -               12.5 grams
    Glycin -                                                    2.0 grams
    Potassium Carbonate -                        25.0 grams
    Add cold water to make -                      1.0 liter

Agfa 14 will give you very fine grain, but is not as sharp as Agfa 8 or Rodinal.

    Fine grain film developer Agfa 14:

    Warm Water (125 F or 52  C) -         750.0 ml
    Elon (Metol) -                                         4.5 grams
    Sodium Sulfite, desiccated -               85.0 grams
    Sodium Carbonate, monohydrated -   1.2 grams
    Potassium Bromide -                              0.5 grams
    Add cold water to make -                       1.0 liter

Comments: I get very nice results with APX 100 in good old Kodak D-76 1:1 (even my Minox  negatives yield sharp, nearly grainless 5x7s) with nice, even,  medium-density negatives that are a joy to print on our good old Omega D-3v  condenser.  However, I definitely use less developing time than Agfa  recommends, and less agitation than nearly anyone recommends:  gentle agitation at 1-minute intervals.

Comments:   Agitation during the first 30 seconds, followed by two inversions at the  beginning of every minute. Works perfectly for my condenser enlarger (Focomat  1c), probabely too flat for a colour enlarger.

ID-11

Comments:  I use 400 ml total (200 ml ID-11 and 200 ml water) in a 16-ounce tank.  I gently agitate for the first 30 seconds (banging the tank several times to loosen air bubbles), then four gentle inversions every minute after that.  I keep it at 68 degrees, but sometimes it's 69 or maybe even 70 degrees at the end.  I use a water rinse and Photoformulary T4 alkaline fixer for about four minutes.  I'm amazed at the end result with this film.  No matter
what film I try to compare it to, this combination of developer and film still gives me the sharpest-appearing images.  It's a wonderful film and developer combination.  I haven't used the 120 format enough to comment because this same amount of development time yields negatives that are overdeveloped, so I'll need to test.
