Technically not infrared, but a different spectrum filter.
The purple foliage comes from using a full spectrum converted camera with an 85A filter. NO color channel swapping or photoshop effects.
What makes this shot unusual (besides the filter) is that the fog is coming from the opposite direction from what it usually does.
Taken with a 650nm IR filter. using a full spectrum modified NEX-5N.
Post production:
3x exposure bracketed images were combined to remove noise and increase the dynamic range. Photomatrix software was used for this. (Highly recommend this product.)
For "Golden IR" effect. Simply swap the red and blue channels in Photoshop.
No masking or per-pixel manipulation was done.

A few days prior to taking this image I was attending a function in the area and the timing happened to coincide with the tail-end of Blue Hour. I noticed three nearby houses decorated for Christmas and like their look and resolved to return at Blue Hour to photograph them. This house is located at 15 Murray Street in Grimsby, Ontario. The owners noticed me photographing the area and offered to turn on the window lights to show the house off to better advantage, an offer I happily accepted. The combination of the lights, the red-blue colour contrasts and the snowy setting really made the scene look like Christmas time to me. - JW

Tech Details:
The original image set used to make this HDR image was taken using a tripod-mounted Nikon D7100 fitted with a Nikkor 12-24mm lense set to 20mm, ISO100, manual white balance set to tungsten, Aperture priority mode, f/8.0, three auto-bracketed images spaced at EV+/-2 around a base exposure of 2 sec with an EV-0.67 exposure bias. HDR processing was done with free Open Source Luminance/Qtpfsgui using the Mantiuk '06 model. PP in free Open Source GIMP: adjusted the tone curve to get a more 'natural' tonal range overall, used the colour balance tool to reduce the red channel as well as green channel and get a more 'natural' colour balance overall, slightly increased overall contrast, used the dodge/burn tool to brighten the edges of some of the edges along the larger snow mounds, reduce overall saturation very slightly, sharpen, add fine black and white frame, add bar and text on left, scale image to 1800 wide for posting.

Just recovered some files I thought had been lost with a computercrash several years ago. These are from 2006 and were shot with the venerable Canon Powershot Pro1
After buying a batch of filters from ebay. I found the 85A + 85 filters (combined) give an interesting effect. So, I took a walk around the block shooting various things.
The white balance was adjust in-camera when the photo was taken. I also used bracketed photos and HDR to increase the dynamic range.
Notice the hill in the background still has green grass.
