Дорогие коллеги .
Предлагаю рецепт проявителя, который у меня работает очень хорошо.
Это модификация ГП.
Фенидон 0,2г
Гидрохинон 5 г.
Сульфит б/в 100 г.
Едкий натр 7,12 г.
Роданистый аммоний 24 г.
Вода 1 л.
Это запасной .
Рабочий 50 мл. запасного +1 л. воды.
Проявитель одноразовый.
Время проявления 5-6 мин. при 18 град.
Фиксаж - Тиосульфат 200-250 г/л
Он прекрасно работает без отбеливания для Денисюка и с отбеливанием для Лейта.
Проявитель
Re: Проявитель
Thank you, Valery, for the post.
For those not able to read Russian (you should practice if you are going to visit ISDH )
Valery describes a modification of a GP-2 developer, that works well according to hist post.
Phenidone 0.2 g
Hydroquinone 5 g
Sulphite anhydrous 100 g (I suppose sodium sulphite according to GP-2 recipe)
Sodium hydroxide 7.12 g
Ammonium Thiocyanate 24 g
Water 1 l
It is a concentrate. Working solution: 50 ml concentrate + 1 liter water
The developer cannot be reused.
Developing time 5-6 minutes, temperature 18 C.
Fixative - thiosulphate (I suppose sodium thiosulphate according to Slavich procedures) 200-250 g/l
It works well without bleaching for reflection (Denisyuk) holograms and with bleaching for transmission (Leith) holograms.
