Some Ilford film developers

[Christopher Walrath]

Here are some more recipes. Ilford this time. Mix chems in the order given and exercise caution when mixing chemistry. And have fun.


ILFORD FILM DEVELOPER ID-2

This is a rapid developer intended for tray processing of sheets and plates. It can be further diluted for use with tank processing as well.

STOCK SOLUTION

WATER(52C OR 125F)------------------750.0 cc
METOL--------------------------------2.0 g
SODIUM SULFITE,DESSICATED----------75.0 g
HYDROQUINIONE-----------------------8.0 g
SODIUM CARBONATE,MONOHYDRATED---43.0 g
POTASSIUM BROMIDE------------------2.0 g
ADD COLD WATER TO MAKE------------1.0 litre

For tray processing, dilute the stock solution 1:2 with water. Develop from 3'00" to 6'00" at 20C.
For tank processing, dilute the stock solution 1:5 with water. Develop from 6'00" to 12'00" at 20C.


ILFORD FILM DEVELOPER ID-67

A phenidone version of the metol ID-2 developer, suitable for sheets and plates.

STOCK SOLUTION

WATER(52C OR 125F)--------------750.0 cc
SODIUM SULFITE,ANHYDROUS------75.0 g
HYDROQUINONE--------------------8.0 g
SODIUM CARBONATE,DESSICATED--37.5 g
PHENIDONE------------------------0.25 g
POTASSIUM BROMIDE--------------2.0 g
BENZOTRIAZOLE-------------------0.15 g
ADD COLD WATER TO MAKE--------1.0 litre

For tray development, dilute 1:2 with water and develop from 2'30" to 5'00" at 20C.
For tank development, dilute 1:5 with water and develop from 5'00" to 10'00" at 20C.


ILFORD FILM DEVELOPER ID-68

This is a replenishible, low-contrast, fine-grain developer that is very similar to Kodak's D-76 in all respects excepting the use of phenidone instead of metol.

WATER(52C OR 125F)----------750.0 cc
SODIUM SULFITE,DESSICATED--85.0 g
HYDROQUINONE----------------5.0 g
BORAX-------------------------7.0 g
BORIC ACID--------------------2.0 g
POTASSIUM BROMIDE-----------1.0 g
PHENIDONE---------------------0.13 g
ADD COLD WATER TO MAKE-----1.0 litre

DO NOT DILUTE.
Develop films from 8'00" to 10'00" at 20C.
Develop plates from 4'00" to 7'00" at 20C.


ILFORD ID-68 REPLENISHER

WATER(52C OR 125F)----------750.0 cc
SODIUM SULFITE,DESSICATED--85.0 g
HYDROQUINONE----------------8.0 g
BORAX-------------------------7.0 g
PHENIDONE--------------------0.22 g
ADD COLD WATER TO MAKE-----1.0 litre

Add the replenisher as needed to maintain the level of the developer. You can replenish an amount equal to the original amount of developer before discarding the solution.

ID-68 is not similar to D76 at all, it's similar to Microphen. Ilford did publish PQ variants of ID-11/D76 in the 1950's and 60's.

Ilford published all their formulae with "Anhydrous" Sodium Sulphite & Sodium Carbonate (after WWII) and there are many mistakes in formulae taken from the Photo Lab Index where the conversions are incorrect, or formulae miss typed. One consequence is that they are a huge number of errors in most US books containing formulae and only those published by Ilford, Kodak etc themselves should be used as references.

To be borne in mind. Thank you for the advice again, Ian.

FYI, I merely wanted to post recipes for reference here on APUG. And there may well be errors. I have triple checked and have relayed the info as I have received it. As Ian points out, that is not to say that those who provided it were not in error originally.

And another remark to the ID-68. It has been mentioned here on another recent thread that Dimezone-S can be substituted at a rate of 1.27x the volume of the phenidone.

What about ID-11 Plus? I was using it and dropped out of darkroom work for a number of years and when I returned, it was gone.

Not familliar. Sure a Google would turn something up.
