What it is

A metol and ascorbate developer that keeps midtones long and grain tight. It is mixed for one-shot use, so every roll meets fresh chemistry and your times stay honest from the first tank to the last.

What it is not

It will not rescue a roll you metered wrong, and it does not pretend to. Push past EI 1600 and you are on your own, but here is where we would start: add forty percent to the push time and expect the shadows to thin.

Storage

Keep the concentrate cool, dark, and squeezed of air. An opened bottle holds six months and a sealed one holds twelve. If it pours the color of strong tea, mix a fresh batch and pour the old one out with respect.
