Just found 3 boxes of 4x5 film in my garage refrigerator. One box of Tri-X 320, two years out of date, one box Illford HP-5, two years out of date, and one box of Kodak color 4x5 portra, one year out of date. Will these still perform normally, or will I lose something in the processing?

The TriX and HP5 will perform like new to have an extra .01 base fog density at worst.
The Portra may have a color shift, the older version did (10 years ago) but the newer version may be better.

That's good news. Thanks.
