Many thank to you, Mr. Knoppow!
Your detail information is worth experience for me. I read
some fomular on
www.photoformulary.com and want to compose by myself.
Best regards,
Xuan Truong
For those interested in formuae here is Ansco/Agfa
130. 130 was called a "universal" paper developer and was
sold packaged in cans.
Ansco/Agfa 130
Stock Solution
Water, at about 125F or 52C 750.0 ml
Metol 2.2
grams
Sodium sulfite, desiccated 50.0
grams
Hydroquinone 11.0
grams
Sodium carbonate, monohydrated 78.0
grams
Potassium bromide 5.5
grams
Glycin 11.0
grams
Water to make 1.0
liter
Add ingredients in order given. Allow each to dissolve
completely before adding the next.
For use dilute one part stock with one part water.
Contrast can be varied over a narrow range by using the
developer full strength or diluted 1:2
130 is reputed to produce more neutral tones (less green) on
many warm tone papers.
For comparison here is Kodak D-72, this is the published
formula for a developer similar to Dektol.
Kodak D-72 Universal paper developer, may also be used for
lantern slides or press negatives.
Stock Solution
Water, at about 125F or 52C 500.0 ml
Metol 3.1
grams
Sodium sulfite, desiccated 45.0
grams
Hydroquinone 12.0
grams
Sodum carbonate, anhydrous 67.5
grams
Potassium bromide 1.9
grams
Water to make 1.0
liter
Note: If sodium carbonate, monohydrated is used the amount
is 79.0 grams.
Add ingredients in the order given and allow each to
dissolve fully before adding the next.
For use dilute 1 part stock to 2 parts water. Dilution can
be varied from 1:1 to 1:4 depending on application.
The amount of bromide in both developers can be
increased if desired to produce warmer tones.
Note: Defender/Dupont 53D is exactly identical to D-72
Agfa/Ansco also published two other general purpose
paper developers which are similar, Agfa 103 and Agfa 125
Agfa/Ansco 103 Paper Developer Stock Solution
Water, at about 125F or 52C 750.0 ml
Metol 3.5
grams
Sodium sulfite, desiccated 45.0
grams
Hydroquinone 11.5
grams
Sodium carbonate, monohydrated 78.0
grams
Potassium bromide 1.2
grams
Water to make 1.0
liter
For use dilute stock solution 1 part stock to 2 parts water.
Dilution can be increased to about 1:4 for slower
development.
Agfa/Ansco 125 Paper Developer Stock Solution
Water, at about 125F or 52C 750.0 ml
Metol 3.0 grams
Sodium sulfite, desiccated 44.0 grams
Hydroquinone 12.0 grams
Sodium carbonate, monohydrated 65.0 grams
Potassium bromide 2.0 grams
Water to make 1.0 liter
For use dilute one part stock to 2 parts water.
Every maker of photographic material had a formula
essentially identical to D-72
If you have Glycin available here is an Agfa/Ansco formula
for a warm tone developer.
Ansco/Agfa 115 Warm Tone Developer Stock Solution
Water, at about 125F or 52C 750.0 ml
Sodium sulfite, desiccated 90.0 grams
Sodium carbonate, desiccated 150.0 grams
Glycin 30.0 grams
Hydroquinone 9.5 grams
Potassium bromide 4.0 grams
Water to make 1.0 liter
For use dilute 1 part stock with 3 parts water. Dilution can
be increased up to 1 part stock to 6 parts water for warmer
tones but the blacks will be less dense.
Note that there was an old German Agfa formula numbered 115
for a quite different developer.
Glycin is an interesting developer but has become
expensive and rather difficult to obtain.
