My experience with industry warm tones paper developer finished years ago with the dismission of Agfa WT. In these years I tested many developers and my favourites mixing by scratch (without glycin) are:
- ID 78 for the real warm tone produces with this chance to increase the amount of Potassium bromide in it that allows you to make your prefered grade of warm tones.
- Gevaert 262 a real warm tones developer, realiable and with very interesting results.
- Gevaert 261
- BJ Warm Tone Developer for Chloro-Bromide Papers a very short life developers, but the warmer of the bunch.
It was posted in the section dedicated to paper developer some time ago.
