Hey guys, I've got a couple of rolls of Kodak HIE in my refrigerator which actually have an expiration date of last month. But I'm hoping they're still good. My question is, will this filter work? Sorry to post an eBay link, but I think this forum's fast enough that I'll get a reply before the auction goes away. From the description; I'm just wondering about the 720nm specification. Is that what I need? I've never shot infrared film, but I would like to before I can't get any more HIE. While I'm at it, can anyone point me to any information on metering this stuff?
