I have been using Delta 3200 for about two years now and probably exposed over 200 rolls. Delta 3200 is a marvelous film but not at ISO 3200. I regularly use it at ISO 1200 and develop in Xtol 1:1 or 1:3. Developed in Xtol it looks more like Delta 400. I especially like to use it in medium format.(posted 8666 days ago)
