Can I use that stock solution further for say another roll of 36 exposure film? From your reply, it seems that the answer is no. Sorry, I could not get the second sentence of your reply. Could you please explain a bit further, if it is not annoying? I shall like to know one more thing. Suppose I am using films without uprating and all the films are of identical speeds. Now there is a term called "Batch Processing" where more than one films are developed in one go. Now suppose that I have 4 rolls of films to be processed. Suppose I am using a negetive developing tank which can accept 2 rolls of film at once. In "Batch Processing", am I supposed to change the developer solution with fresh solution after processing 2 rolls or shall I continue using the same developer solution?
