The first developer in my E-6 kit has gone bad - there are some crystals floating on the bottom. I just ordered some replenisher, but the starter is out of stock at unique photo. Would that be a reasonable approximation to just use some 5% acetic acid with 15% sodium bromide, and then adjust based on the results? I got these numbers from the MSDS, which sounds reasonable to adjust Ph and add some restrainer. The MSDS also mentions potassium iodide, but less than 1%, so I don't feel very confident of how much to use... Any suggestions? Eugene.
