What I find of the most interest in Colin's IR rendition of the cathedral is the poignant portrait of the lady with the walking stick on the right. Almost an apparition, but she is very real.
Its funny sometimes how we get focused on different issues as we move forward, mine has been stitching and The Edge of Hell, appropriately named in this case, has been quite a learning experience. To pass this along, when merging large numbers of images, it would appear that doing sub merges of smaller groups of 2-3 and then merging the results from those will yield much better alignment.
So this is where the edge of hell stands now, same images, much different result. Please feel free to pick at this if you like, it will only help me further identify stitch issues and potentially resolve them.

Serge, if I've not said it yet, enjoying the virtual Italy tour. If all this uncertainty ever clears up there's some pent-up Europe touring in my blood I think.
Ray, glad you are enjoying the tour, it was a great little adventure. I may have a few more photos to share.
The uncertainty has the benefit of much lower crowd levels. The entire trip was easier than expected and the only pain was the required Covid PCR test one day prior to departure. I suspect the testing requirement will remain in place for many moons to come.

Have been thinking of an IR try myself, have to time it for when there's sun peaking out enough through the winter skies.
Film or digital Samy?
These recent winter IR images are softer than I'd like.
I was expecting more 'snap' at ISO 200 on an FX sensor.
It could be that my camera holding technique has gone downhill since I got the Z6.......

That newfangled high tech antivibration stuff is making you lazy

I actually tried a shot right after work today (or a whole 120 roll which turns out to be 4 shots). The weather super computers were claiming 20% cloud cover at that time but in actuality it was more like 50% or more, so will see if the calculations worked out.
Colin, I noticed some of the outer parts of the cathedral image were softer. Could it be the aperture got left to a more open setting?

Oh boy that must be an effort (for your sofware) stitching those electric lines.

Nope, 28 core I9 under the hood, build my own PC's because I do a lot of stuff on that PC. My ham radio stuff requires some heavy duty CPU. Usually when I build, the PC benchmarks 98th percentile and still hits 90th in 5 years. I try to make sure it can process images like a real graphic workstation. Only place I skimp is on monitor where I usually use a large TV/monitor since I don't need the high frame rate gamers do.

From fall of 2020. I struggled with leaving that protruding branch at the upper right, but decide I liked the crop ratio and left it. 85mm f1.8H.
Ray, that branch works well, adding a little red touch against the large evergreen on the left. Well captured.

rafael,
Thats the thing - the sharper the lens the more the fly poo shows. Your 55mm f3.5 compensating lens is a winner!

James, if I want to show lenses at this magnification I will have to clean them under the microscope! Posting these photos is about sharing the craftmanship built into the original Nikkors, but it becomes so easy to see tiny bits of dirt in the grooves, dust specks and tiny scratches that a bath and make up session is warranted.
But - isn't that iridescent chrome and engraving just beautiful!. At least to an engineer, something about ground and polished lenses and machined metal turns me on.
