Photo Formulas and Techniques

Various photo formulas from multiple sources

Sandy King developed Pyrocat HD – a semi-compensating staining film developer with high accutance. He then developed other fomulas (the glycol ones with the help of Pat Gainer) that work with subtle differences.  These developers seem popular with shooters of all formats. Some photographers think the tanning action of the Pyrocatechin helps reduce scrathes in [...]

510 Pyro was developed by Jay DeFehr. It’s a simple developer that keeps indefinitely and can be used at many dilutions – usually 1:100 – 1:500.     Warm triethanolomine (TEA) 75 ml Ascorbic Acid 5 g Pyro 10g Phenidone 0.25 g Triethanolomine to make 100 ml   I usually make 4 times this amount [...]

Hypercat was developed by Jay DeFehr as a high acutance, catechol-based tanning/staining developer. Mixed in glycol, it has a long shelf life.     Hypercat A Ascorbic Acid 1 g Catechol 10 g Propylene Glycol 100 ml   Hypercat B Distilled water 750 ml Sodium Carbonate 200g Distilled water to make 1 L   People [...]

Pat “Gadget” Gainer developed PC-TEA as a simple to make alternative to Kodak’s X-tol.  It’s a one solution, one shot developer. Some folks found it prone to fog, so they experimented with adding Potassium Bromide.  Here’s the version I use.   Triethanolomine heated to about 180F 200 ml Ascorbic Acid 45 g Phenidone 1 g [...]

This is a fine-grain developer recommended for all Ansco roll, pack and 35mm films. It can also be used for obtaining soft gradation with Ansco portrait and press films.  It is recommended for motion picture negative development.  This soft-working, fine-grain developer may be obtained in packaged form by ordering Ansco 17 developer. Hot Water (125F [...]

Add 1/2 to 3/4 ounce of replenisher to Ansco 17 for each roll of 120 film or 36-exposure 25-mm film (or equivalent) develped. Maintain original volume of developer, discarding if necessary some used developer. No increase in original developing time is necessary when replenisher is used in this manner until the developer is exhausted. Available [...]

This formula is similar to Ansco 17 but due to the use of sodium metaborate as the alkali, permits greater variation in developing time.       Hot water (125F or 52C) 750cc (ml) Metol 1.5 g Sodium Sulfite (anhydrous) 80 g Hydroquinone 3 g Sodium Metaborate 2 g Potassium Bromide 0.5 g Water to [...]

Maintain original volume of developer, discarding for necessary some used developer. No increase in original developing time necessary when replenisher is used in this manner.   Hot water (125F or 52C) 750 [...]
