I am a amateur using the Tetanal Colortec RA-4 for processing in the Jobo CPP-2. I am living in Hong Kong and used to get it from B&H Photo of the USA. However, the kit is no longer available in B&H photo. I tried to get it from somewhere else but found out that it cannot be sent overseas now, even available. The B&H photo guy advised me to get the Tetanl RA-4 Color Developer Starter. I am confused. Is the starter to be used with the developer replenisher instead of using alone. Please advice. The place I am living is lack of chemicals for home processing. Is there any alternative. It seems that the airflight rule for chemicals has tightened as I still could get them shipped a few years ago. I do not want give up my own darkroom. It's sad.
