H & W Control Film Developer

Freshly mixed, H & W Control will give similar results as the commercially packaged Bluefire HR for Bluefire Police, Kodak Technical Pan, and similar films. For ordinary films, H & W Control will yield low contrast, often unacceptably flat, negatives. The shelf life will typically be six months or less, depending on storage conditions. The Stock Solution is pale yellow and should be discarded if pink or red.
