Hello all, I recently bought some developer for cheap, XTol and Rodinal. My trouble is that the XTol is long expired (5 years or so) and I'm not sure I should trust it. So my questions are : - how do I test it (a clip test showed some activity, but I'm not sure it's as active as fresh XTol) ? Do I run a film through any camera and process it ? Will these results be meaningful for the shelf life of my 5 liters ? - Supposing it's fine today, will a clip test be meaningful in a few months to decide it didn't go bad ? I'd rather throw it than risk ruin some films, but on the other hand, if it works I'd be happy to use it... To put things at worst, the price I paid for the lot (XTol + Rodinal) is about 1/2 price of fresh Rodinal, so if I only use the Rodinal it'll still be a bargain.
