Continuing with this year's creative foray into winter IR photography.

The shapes sculpted by wind and snow are wondrous, and in infrared become otherworldly ...
Picking up on the conversation from last week, the challenge of lens performance in IR can make things quite interesting. For the image above, I used the Canon EF-M 18-55 standard zoom. The performance of this lens for infrared depends on shooting conditions given my experience. In harsh sunlight it can produce a 'hot spot' in the centre of the frame at medium to small apertures. My default aperture for most shooting is f/8 and for IR, this lens performs better at f/5.6 or lower, making depth of focus an issue for some shots. Taking the image above as an example, I was able to get reasonable focus sharpness at 18mm with f/5.6 for the foreground snow drift, which is the main subject. The background however is nowhere near sharp and this was acceptable as the birch tree and distant cottage chairs provide some context without challenging the main subject for the viewer's attention. No seen, is the hot spot that required some tweaking in post processing to remove a colour and brightness shift. Given the subject of the photo, this was not difficult however with different subject matter it could prove quite challenging.
The journey continues ...
