In truth it isn't winter yet, and in a few months I'll look back fondly to how warm these days were. But the city is getting ready for it, with holiday-everything promotions and skating rinks popping up around the place. These photos are from a couple of casual days spent carrying my infrared camera – casual photography and infrared are both things that I don't do as much as I used to, so I wanted to try them out again.

Normally my IR photos are in black and white, as they should be when taken through an 820nm filter. These are colour files, though, and they have some trace of tone left in them. The warm or cool tones are from biasing the white balance to different areas of the frame, but the whole thing is likely an artifact rather than actual colour information.

I remain unconvinced about casual photography. Popping out with a camera can be fun and can get some lucky shots, but mostly I feel like I'm being a prat for the sake of images that will die in the dark of my hard drive. Do these photos add anything to an ongoing conversation, bring a unique sensibility to their subject matter, or record a moment of significance?

No, I don't really think so, either.

The other question I'm trying to answer is whether I should go ahead with converting my mostly-idle X-T2 to infrared. I haven't been using my IR cameras much this past year – I've been distracted by a couple of other gimmicks – so breaking out the Coolpix A-IR was a useful refresher. In this case, the answer is an easy "yes". The look of the photos still grabs me, but using the 28mm-e Coolpix had me constantly wishing for a different focal length. And with that conversion finally done, perhaps by this Spring, maybe I'll be able to integrate IR photography into the things that I already like.

Yes, that probably means IR photos of aircraft are in my future. I'm excited to think about how well that will be able to cut through haze and distance, and what the liveries will look like in a part of the spectrum that we were never meant to see. Those effects of infrared simply can't be emulated, or even predicted.
