I've recently was looking trough E-pay, and noticed the many different Tungsten balanced films that are no longer made.
I dug into their datasheets and found interesting info when comparing with the current offerings:
- They seem to suffer less from reciprocity (Fujichrome 64T type II seems real good with only +1/2 stop needed all the way to 256 seconds exposure); and
-Can be converted to daylight with less of a penalty (Portra 100T: +2/3 stop) than converting daylight to tungsten(Portra 160, Ektar 100: +2 stops (!)).
So my question: Why were they all axed? Were they considerably more expensive than their daylight counterparts, or the converted color rendition wasn't really great, or something else? To my eyes it seems nonsense, they seem all around more versatile.
