pico Posted August 20, 2011 Share #1 Posted August 20, 2011 Advertisement (gone after registration) Today is the day to test some Kodak 4x5 infrared film that's been frozen since about year 2000. My first pass left me with fogged film, right into the borders. Since then I've learned a bit about safer film holders, but someone told me that IR film will fog even in steel canisters due to long term cosmic radiation. I thought you 35mm experts might know something about that. I don't believe it. Do you? Anyway. I'm developing one sheet without exposing it. Another put into a (supposedly) safe holder and left in the sun. Hoping for clear negs. (And processing in a stainless steel Nikon reel tank to be sure the plastic tanks aren't IR translucent.)

treeplanter Posted August 20, 2011 Share #2 Posted August 20, 2011 I found a roll of 35mm 1980's expiration date Kodak B&W HIE film in my freezer a few years back. Out of curiosities sake, I shot an exposed it as normal. It actually came out not too bad though the look of it was a bit different than "current "HIE (a bit more washed out, something you can partially correct for in Photoshop). My guess is that your 2000 stuff will turn out OK too. Jim B. Link to post Share on other sites More sharing options...

EMMA That's a good thought, but I rebuilt a Printex 4x5 just for this purpose. It uses a steel cylinder instead of bellows and is light-tight. And it has a rangefinder. (With LF it's not very hard to correct IR focus). Here is a picture of my first one w/o the rangefinder (I have 4 of them now). (If you read the article you will find my real name.)

pico Posted August 21, 2011 Author Share #5 Posted August 21, 2011 My objective is to reshoot the following image so that it prints well in 16x20" You see, without infrared nobody can see the distant geography due to haze. Ever. I will shoot with a longer lens. http://www.l-camera-forum.com/leica-forum/members/23965-albums4157-picture5809.jpg This area is called the Driftless Zone. We will see if it works out.
