Ouch, I'm not too fond of the results with a red filter. I take it a Cokin 001 yellow is about what I'd need?

I doubt mine was frozen. Refrigerated if I was lucky but when I purchased it it was not in a fridge. I put it into the freezer when I got it back though.

Do you know of where one would obtain refrigerated/frozen EIR?

I guess I should set to about 200 or 160 since I'd have lost IR sensitivity...
