Atomal/Calbe A49 - Successful clone.
Last month I was make some experiment with different formulas like Atomal/Calbe A49. I use CD-1 because it available in my country. I'm really impressed with results. Some samples:
CD-1 + Ascorbate + Kodalk, Ilford HP5+ @400
CD-1 + Hydroquinone + Borax, Ilford HP5+ @400
