I'm running out of my stocks of Kodak Contrast (Process Ortho), which I shoot at ISO 12 and DBI. I'm looking for a 4x5 replacement. ISO isn't much of an issue, since they're basically all ISO 100 or slower. As far as I can tell, this is what's out there: ADOX ORT25 EFKE PL 25 ORT (Same as ADOX?) Rollei Ortho 25 (Same again? These three are all FK, no?) Ilford Ortho Plus (Gone from Freestyle website...) Maco/FK PO 100c (I'll have to call freestyle about this one...) Are there others I've forgotten? Does anyone have experience with any of these? I was hoping to get a little input, advice, recommendations, or cautionary tales before I run out to order a bunch of different ones. If it comes to that, then I will, and test them all. Thanks in advance for any advice.
