I think this was around the time I decided to really start exploring false colour infrared. Capture here is with a full spectrum conversion and 720nm filter, and even the weak colours here were enough to inspire me to play with some different filter options.
It's continuing to be cloudy/hazy these days, so here's another from the archives. Amsterdam with a full-spectrum conversion and a 630nm filter, post-processing in ACR and Photoshop for channel mixer and hue refinement.
IMO you have a pretty severe blue color cast going on. Here's what I did with some level adjustments and color balance. It may not be perfect but gives you an idea of what I think is closer to the correct color.
My new full spectrum camera is here! The old GF2 was one of my first m4/3 cameras and has served me well over the years but it was time for something a little more modern. I'm still getting used to Olympus ergonomics but so far I'm loving the output. Full spectrum conversion with a blue/IR filter, three photo panorama stitch all processed in Lightroom.
Sigma SD1 with the removable UV/IR blocker out, Probably the 17-50mm zoom. No filter on the lens, so full-spectrum shot.
Converted to RGB by RawDigger and then messed with in RawTherapee; didn't save the PP3 sidecar file and don't remember what I did, sorry. Might have WB'd on the light gray transformer.
I believe the SD1 uses a Foveon sensor rather than a more normal Bayer filter. With this set-up IR shows mainly in the red channel. This alternate IR mapping is what I use a couple of ancient SD14s for. :)
I use my foveon camera in a slightly different way, adding a #58 (green) filter, to the sort of arrangement used by @xpatUSA. This filter reduces the IR by about 50% (other #58 filters differ here!) using a fluorescent WB correction & then minor hue adjustment in post, I get results like this:
