Alright, to give an update: I listened to everybody's advice and tried a variety of fixes. I had success with pulling the compendium shade further out while also covering the camera with my dark cloth as added precaution. The negatives have increased contrast by eliminating the excess fog. The highlights are about the same density as before, but the shadows are reduced to a normal level. Thanks to everyone that chimed in and gave suggestions.
Glad you got it figured out. I kind of enjoy the troubleshooting process myself, but there's a point where you just want to take photos and not fuss with it. At least now you are past the fussing with it part and get back to taking photos.
Excellent news, Greg.
