    Ilford Multigrade vs. Ilford PQ Universal paper developers

    ...there were complaints about shifts in image colour abnd variations in warmth, so they added Benzotriazole to control this the new formula was ID-62. These where powder developers. PQ Universal is a liquid concentrate, the Sodium carbonate is replaced by Potassium carbonate and Sodium or...

    I MADE A DEVELOPER TODAY, YES A NEW ONE!

    Looks like you're re-inventing Ilford's ID-62 developer which is the basis of most of Ilford's commercial paper developers. This is a concentrated version, however I replace the Sodium Carbonate with Potassium carbonate & Sodium or Potassium Hydroxide as it keeps longer without any...

    Reverse engineering a developer?

    Bromophen is very similar to ID-62, and I posted a link. The difference is that the packaged powder form has a small amount of Sodium Metabisulphite in Part A which helps preserve the developing agents in the packet, Kodak do the same with Microdol-X, but it's not required if made up as a...

    ID-78 paper developer color

    That makes sense, 62 g (anhydrous) and 72 g (monohydrate) are equivalent. I prefer the monohydrate as it is more stable. Given time, anhydrous will be monohydrate anyway.

    Choosing a (paper) developer

    ...In which case there are good developers which use few ingredients and are easy to mix and those with more ingredients and more difficult to mix. Ansco 120 is of the easier type while Ilford's ID-62 is a more difficult type. If properly used both will make good film and paper...

    Home Made B&W Developers.

    Look at ID-20, ID-62 & ID-78 :D ID-20 was sold as a PQ version early 60's but there were image colour problems so it was re-formulated as ID-62, take away the Benzotriazole & put back the Bromide & warm tone ID-78. Ian

    B&W reversal

    Probably, it's possibly not that different, Ilford used to recommend ID-62. Multigrade dev is balanced to give the same image colour regardless of Grade. Ian

    Formulating cold tone paper developers

    ...FB and the difference in colour was quite distinct. The left side was developed in the PQ version of ID-20 (Forte FD-203 which is ID-62 with no benzotriazole), the right with the same developer with Additive-X. However Additive-X which is Thiourea (Thiocarbamide) is problematic, the...

    ...then added 1g Benzotriazole to the working solution which seemed counter productive, and resulted in odd changes in tonality and contrast. The ID-62 developer with reduced Potassium Bromide and the addition of Benzotriazole in 20, + 10, + 20, + 30, + 20ml increments produced similar results...

    Formulating cold tone paper developers

    ...The level of Hydroxide is Image colour/tone is related to grain size, it would be interesting to see what effect dropping the Sulphite level might have in a formula like ID-62 along with the increase in Benzotriazole. In addition switching from Phenidone to Metol which is colder working. Ian

    Less Benzotriazole should give colder tones? Would you expect ID-62 with additional Benzotriazole to give colder tones? Tom.

    You've probably rather over done the Benzotriazole, essentially you've gone towards ID-62/ID-20 it should be quite cold. Ilford Cooltone dev used a proprietary agent instead of Benzotriazole. Ian

    ...Cookbook, and Silvergrain.org. For instance ID78 should have 1.25g Bromide not 0.2 as you're showing, ID-20 should be very similar to ID-62/78 with Metol instead of Phenidone and less bromide than ID-78, it's incorrect as is ID-36, . Ansco 103 is wrong as John says, there are two versions...

    Cool tones, Warm tones Neutral tones

    I've been making up concentrated ID-78 for over 20 years now and never had a problem. You can replace the Sodium Carbonate with Potassium Carbonate & Potassium or Sodium Hydroxide which allows far greater solubility. Assume Potassium Carbonate (anhyd) 12 g + Potassium Hydroxide 4 g is approx...

    I just ordered some liquid Dektol...

    Liquid Dektol is a Dimezone/Hydroquinone liquid version of D72, it's probably like PQ Uninversal or ID-62 which is the PQ version of theprevious MQ developer ID-20. It may have a different name in the US. Often the Sodium carbonate is replaced by Potassium Carbonate & Sodium or Potassium...

    PQ Universal vs Harman Warmtone developer??

    ID-72 is the PQ variant of ID19/D19b and is probably more contrasty than PQ universal. ID-62 is closer, with no Benzotriazole & additional bromide it become ID-78 which is very similar to Neutol WA. Ian

    Dektol won't offer any advantages at all over PQ Universal. Dektol and ID-20 are very similar, ID-62 is the PQ version. Ian

    Homebrew alternative to Ilford MG Developer

    ...the information. I will try the Ansco 103. Ian - the formula for ID-78 is in the Darkroom Cookbook (courtesy of yourself) but there isnt one for ID-62. How much Benzotriazole does it have and how much less Bromide? Also is the Sodium Carbonate monohydrate or anhydrate? Cheers Ritchie

    Homebrew alternative to Ilford MG Developer

    Agfa Ansco 103 is very close to ID-20, ID-62 is the PQ variant of ID-20. Modern commercial liquid developers such as Multigrade, Neutol NE & WA etc are usually PQ devs (or more commonly Dimezone instead of Phenidone) and the alkali is changed, so instead of Sodium Carbonate they use a balance...

    Homebrew alternative to Ilford MG Developer

    What about ID-62, it's fairly similar to Multigrade dev. Leave out the Benzotriazole and add more Bromide it becomes ID-78 a Warm tone developer, or add more Benzotriazole and it will become much Cooler. ID-3 is a good alternative to Selectol Soft/Agfa Adaptol. Ian

    New Arista Premium 100 & 400 films
