I have felt the need for an ISO 200 B&W film for some time. It would allow an extra stop for using a deep yellow #15 filter and still allow using a small aperture when needed, with a high enough shutter speed. Kodak used to make a double-X (XX) film rated at 200 (as I recall). It would be a welcome addition. In fact, if XX were subjected to the same upgrading over time that Tri-X has received, it would probably be a great film!(posted 8479 days ago)
