I used to use a lot of XP2, and mostly use TMX/TMY these days. XP2 has a characteristic curve with a fairly long toe and prominent shoulder that starts in the mid-tones. T400CN has a curve much more like TMX/TMY - not a terribly long toe but nearly linear up into the highlights. I happen to vastly prefer this look, but studio portraiture might be better for XP2. T400CN is also a faster film than XP2 (honest EI 400 vs. EI 200 for XP2) and much finer grain. If you plan to use it above EI 800, Kodak says you must use push processing.(posted 9743 days ago)Dana K6JQ Dana@Source.Net
