Erm... you've lost me a bit here. Not difficult, maybe!

I thought the Iodide solution we added to FX1 and the like was suppossed to *Increase* the edge effects? With modern film it appeared (so I've witnessed myself) to have little or no effect. Why would you want to prevent edge effects in a HDD developer? Does this explain why I always found FX1 to be a bit lacking when it came to the pronounced mackie lines I was hoping for?
