Using an orange filter on the full spectrum Sigma SD14 without the IR cut filter. Converting direct in Rawtherapee with default pp3 file to convert the raw file to have blue sky and convert the infrared to yellow-gold. Converting in Rawtherapy does not get the full resolution from the file I think.
Just for fun, this is a weird false-color version of part 4 of the "lost gorge series", where the water turned out a bit green-ish.
Take care folks.. 🌼
Technically that is mercator projection, consisting of 21 individual photos, ~219,6MP, cropped to 8:5 with 14366 x 8979px, 129MP.

Using this setup and corresponding workflow for some years now, I'm amazed and shocked that: I still blunder and make mistakes but also still discover ways of improvement (which are perhaps 2 ways of saying the same thing?).
This is more nerd-talk (feel free to skip): I think I found the reason for my increased struggle with artefacts in the sky with the latest panoramas. And it was an "improvement" on one level. 🎉
I stopped developing the raw sources like it was the final thing or look, and treated it more like a preparatory step for stitching: get rid of clipping, reducing dynamic range, making the pano as well-behaved as possible (which often means flat and dull looking, but that's ok at this stage), exploiting the RAW format.
However, this also made these artefacts prominent and persistent. Some changes are made during and for stitching (not necessarily for aesthetics) and post-stitching I'm with TIFF.
Trimming/cropping in Ps due to huge size, perhaps some tweaking already, then final development in Lr, multiple b&w conversions, usually more crops etc.
So I re-worked this project (meaning I already did it back then) and noticed the seamless sky right away, realizing, I need to preserve the natural IR shadows and blacks in RAW format as much as possible! It's not the ultimate solution (for this panoramic layout), but it helps greatly with the artefacts and the shadows are usually not the problem, I just need to check the highlights in RAW, to leave some room for the final development to not blow them out there.
Ergo: While this might not be the best "composition", I'm quite pleased with the development and used a (false-)color scheme I haven't in a while. This view is a bit further back (where I could utilize the shade of the trees) as this one:

Technically, the source of this is a 36-piece mercator projection (trimmed 20791 x 12375px, ~257,3MP) that I vertically cropped to about 214,5MP.

These are some of the first images taken whilst testing out a newly converted full-spectrum Lumix GX1. These were taken with a 590nm Infrared filter on the lens. They were R-B channel swapped in CS6 then processed in LR5.

This was taken along the River Wey above Triggs Lock. Shot with a Full Spectrum converted Lumix DMC-G1 with a 590nm IR filter fitted on the lens. This image is a non-R-B swapped version of an earlier upload.

One more Fullspectrum Experiment:
I try to make the best of these days with the same subjects over and over again ... And I'm lucky I have a lot of things to do on my list: It's almost 2 years ago I got some rather strange IR-block filters.
Here I used the B+W #470. It's a blue-greenisch color, pretty dark. It's actually a technical filter, to be honest I didn't understand what exactly it was used for (maybe 40 years ago?), but I understand it blocks IR. On the Fullspectrum camera it's always easy to check this: If you see green more or less normally, IR is more or less blocked.
I needed to custom white balance there photos, again simply on the birches bark. A litte tweaking was necessary. What I get are very rich greens. Magenta comes bold, also, red is more subdued here, but it's not absent. I like the colors quite a bit, I tried to get away from a too extreme rendering, but still the cooler tones are somewhat dominant (or is it just me imagine that?)
I only used this one filter on a Minolta 70-210/4 (the manual focus variant of the famous beercan) and used it wide open (the filter needs a lot of light) and at it's minimum focus distance. Not too bad for an old zoom wide open!

Now that it's gloomy and frozen outside, it is nice to see some lush radiant IR vegetation, and flowing non-icy water. 😊
Here it's flat and would be possible, but I don't particularly enjoy fighting through the bushes (especially with a backpack and tripod + pano head + camera + expensive filter on my sholder), so for these type of things, exploring gorges etc., I just wear old shoes without socks and wade in the stream, much easier and there are still enough obstacles, it's not like it's getting boring or so. And the option of dropping gear in the water or on some rocks sustains attention for sure.

Juust so, ..early February, meaning winter, still psyched about the color craziness at this time of the IR year, doing stuff handheld, 😊 that was kinda 'new'..

From early December, when I got the filter, perfect conditions for IR obviously, but I just had to go out, ..obviously. 😜
Wanted to see what this wavelength does to the fog, but somehow I ended up in a bubble of no fog / clouds while it was all around. This is my own sepia development, but frankly, it looked almost the same in real life, very bleak! I let you discern if or how much of the / our beloved IR features are present in the photo..

Hazy, windy afternoon at the beach and these kite surfers were taking full advantage of the moment.
I thought infrared with 850nm filter could kick up the contrast a bit.
