Japan Camera Hunter StreetPan 400 is a high-speed panchromatic black and white negative film featuring a nominal sensitivity of ISO 400/27° and a fine grain structure. Using a unique two-layer emulsion, this film is ideal for working in low-light situations and also retains a low grain profile that makes it especially well-suited to scanning. Also distinct, this film has spectral sensitivity to 750nm, which helps to cut through atmospheric haze and fog for greater clarity and contrast. This extended red sensitivity also benefits working in lower light conditions, such as during dawn and dusk, and its wide exposure latitude allows you to rate the film between EI 200-500 for acceptable results. It has low base fog levels when processed at high temperatures, making it suitable for high volume processing, and the emulsion is coated on a 100Âµm-thick transparent polyester base. Additionally, base substrate layers offer permanent anti-static qualities and a gelatin coating has also been applied to the back layer to resist scratching.
