Infrared compared to Panchromatic Film - Example Three

One more example comparing Infrared to Panchromatic film.  This time there are two examples of the panchromatic films.
I took these shots of high water at Abraham Lake in the fall of 2022.  The lake is actually a reservoir created on the North Saskatchewan River by the Bighorn Dam.  This is the same lake that experiences all the ice bubbles in winter.  The dam is closed and the reservoir is allowed to fill during the summer months, then the water is slowly released over the winter.  In the past couple of years the reservoir has been filled to capacity, right up into the trees and very close to the David Thompson Highway in places.
The upper image is the one that I shot on Kodak High Speed Infrared.  The film was loaded into the film holder on September 15th 2022, and the image was taken on October 6th 2022.  The exposed film was pulled from the holder on October 10th 2022, and stored in the fridge until I developed the film on January 14th 2024.  The film reached its expiry date in August of 2001.
I shot this on October 6th 2022 at about 3:30 in the afternoon.  I used my one of my Ebony view cameras and a Fujinon-W 250mm lens.  A number 25 red filter was used, with no filter factor.  The film was rated at 100 iso and exposed at F29.0 for 1/4 second.  Development was in Kodak T-Max Developer, diluted 1:6, for 6:45 minutes at 22C [71F].  This one turned out pretty well, and even though it sat in the fridge for  over a year before being developed, it was exposed shortly after being loaded.  In my experience, prompt exposure and then a return to cold storage seems to yield reasonable results.
The second shot was actually taken moments prior to the infrared version.  It was taken on Fuji Neopan Acros 100 film, rated at 80 iso and given N+1/2 development in Rodinal developer, diluted 1:50.  Exposure was with the same camera and lens, and a number 25 red filter with a three stop filter factor was used.  Exposure was at F45.0 for 8 seconds.  Development was with hangers in open tanks for 11:00 minutes at 24C [75F].  The long exposure rendered the water with a really soft, silky look, with the value deepened considerably by the red filter.
The third shot was actually taken right after the second, and just before the Infrared.  It was taken on Fuji Ilford HP5+ 400 film, rated at 320 iso and given Normal development in 510 Pyro developer, diluted 1:100.  Exposure was with the same camera and lens, and a number 25 red filter with a three stop filter factor was used.  Exposure was at F22.0 for 1/4 second.  Development was with hangers in open tanks for 7:25 minutes at 24C [75F].
The images certainly look fairly similar, though there are some obvious differences.  All show motion in the leaves due to the breezy conditions and the long shutter speed.   The extremely long exposure of the middle shot gave a totally different look to the water.  The infrared film shows more of a glow on the tree trunks and in the leaves.
