Comparison of Infrared to Panchromatic Film 2

I did a blog post on this same subject a few years ago.  I recently processed a batch of Kodak High Speed Infrared Film that yielded some half decent images.  Here are some of those compared to images taken at the same time, on standard Black and White Film.  With each pair, the one on the left is the infrared version.  

The first pair is some backlit pine trunks at the Alexo Cemetery.  The right image was taken on Adox CHS-50 film developed in Rodinal.  Both images were taken in late June, on a rather wet and overcast day.  Obviously the sun was starting to bust out a little by the time I took these shots in the late afternoon.  I can't recall but the clouds must have rolled in again by the time I took the seond one on IR.   I used a #8 Yellow Filter on the Adox film, and of course a #25 Red on the Kodak High Speed Infrared.  If you look closely at the IR image you will see that the vegetation has a glow, and the backlit trunks are darker.. Also the atmospheric haze in the background is reduced a little.

The second pair is a shot of Blackmud Creek in Edmonton.  This was taken in mid May of this year.  I used a #25 Red filter on both shots.  The left one is of course the Kodak High Speed Infrared, while the right one is Kodak T-Max 100 developed in 510 pyro.  The vegetation is lighter, and the water darker in the IR image.  This is very typical of this type of film.  The sky is not much different, which is a bit of a surprise as IR usually yields very dark skies.  But in this instance there was backlight, so that is probably the reason.  The staining pyro developer nicely held the highlight values in the clouds. in the T-Max image.

The last pair is a shot of the train station at the abandoned museum.  The right image was taken on Fuji Neopan Acros 100 film, developed in Rodinal.  I used a #25 Red filter for both images.  It was a relatively sunny day in late August, with partly cloudy skies.  This is much more typical of the different tonality exhibited by Infrared film.  Even in these small screen shots the grain of the Infrared is more evident.
