Harman Direct Positive FB Paper Glossy 4x5 25 Sheets paper is great to use in pinhole cameras. You get a positive print straight out of the camera. No need for a film negative or inter-negative. You develop Direct Positive paper in conventional black and white print chemistry. The result is a beautifully rich fibre based print. This is a fixed grade, high contrast paper. It is similar to Ilford Multigrade grade 3½ - 4.
