I'm used to Ilfochrome. I just realized there is no recommended filter pack on the paper I bought. It's the Arista paper. I suppose it's pointless to ask where to start since everyone will be using different enlargers/chemicals/films, but I'll ask anyway. Any suggestions? I'd like to minimize my time and waste. I can then use this thread for other stupid questions that come up as I climb the learning curve.Does any RA-4 paper come with filtration suggestions, ior do I have to dial in each pack separately? Or is it all rock solid and consistent batch to batch, unlike Ilfochrome?
