Last Batch of Infrared Negatives

A week ago I processed my last batch of Infrared negatives... for now...  This included nine more sheets of Kodak High Speed Infrared, as well as eleven sheets of Maco IR820C Aura.  This European film was discontinued some time ago, with the "fatal equipment failure" at the coating plant in Croatia.  This forced the elimination of a number of my favorite films including Efke PL25M, Adox CHS50, and this infrared emulsion.  I never quite got this stuff nailed down.  Exposure is complicated, since light meters measure infrared wavelengths combined with visible.  Refining development time is by trial and error, and I was just starting to get comfortable with it, when it was discontinued.  I think I still have a couple boxes left in the freezer and will try to use it up on some subject matter that it is suited to.  Here are scans of some of the better negatives from this recent batch...

These first two were taken on the Maco IR820C Aura.  Some backlit aspens out at Elk Island National Park, taken way back in the summer of 2011.

Kind of jumping around a little here.  These next two were taken at Bryce Canyon National Park in Utah back in October of 2013.  These were both on Kodak High Speed Infrared.

As I continue to attempt to catch up on my backlog, here are a couple of the oldest.  These two were taken in the Fall of 2010, out at TL Bar Ranch in the badlands.  These were on Maco IR 820C Aura.
