Hi Art,
As Wade said, Elite Chrome 200 has a slightly
better Ha response, while the Provia 400F has a slightly better blue
response. Also, I've found in shooting Comet Machholz, the Provia does a
little better on recording the comet and tail. I push both films 1 stop
so, understandably, the Provia records more at twice the speed. Here's an
example of Elite Chrome 200 and also one of Provia 400F...
Both are very good for AP.
