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.

To get building visit Thingiverse:
The sun had set out behind the house and the deck had a rather harsh light that glanced off the glass surface of the table. Lights from inside were hitting the clay pots and the yellow Muskoka chair (that is what they are called in this part of the world, but naming always seems to reflect regional vacation areas). It was actually much darker than I presented in this image, but it just looked like the summer on the deck feeling that the lousy summer weather this year had pretty much not produced. Ah well, there is always next year. - JW
Date Taken: 2014-08-27
Tech Details:
Taken using a tripod-mounted Nikon D7100 fitted with a Nikkor 12-24m lense sett to 12mm, ISO100, Aperture priority mode, f/8.0, three auto-bracketed exposures spaced at EV+/-2.0 around a base exposure of 20 sec with an EV-1.67 exposure bias. HDR processing was done using free Open Source Luminance/Qtpfsgui using the Mantiuk06 tone-mapping model to bring out textures and provide a gritty look, settings as indicated below. PP in free Open Source GIMP: adjust the tone curve to get a more natural look by shaping the curve to a classic 'S' shape, slightly boost contrast, darken the sky in the top left to better match the tone along the upper right, dodge the red pots a bit, sharpen, add fine black and white frame, add bar and text on left, scale 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.

The shoreline of Lake Ontario in Grimsby, Ontario has a very substantial shore ice formation following the extended cold spell we have been experiencing. On Friday Morning (Jan 24) we finally had some early morning sunshine as well as having very cold conditions (-20C/-4F) before considering wind-chill, and very still air. This is the exact set of conditions to get sea smoke, essentially fog off the warm lake water rising into the super cold air. Sadly, there was just enough of an off-shore breeze, slight though it was, coupled with a thin skim of ice on the dead still lake waters, to limit the formation of the sea smoke to an area starting about 2 km (1.5 miles) offshore. But the colours were were looking very warm in the early morning/Golden Hour light, even though it was so cold I lost all feeling in my fingers in about 60 seconds once exposed and had to keep putting my hands into my pockets to prevent frost-bite. Here you see a section of shore ice along Nelles Beach in Grimsby, with the sand inclusions from periods during which the shore was clear of ice, and sand from the beach was blown out onto the continually forming ice surface. You can also tsee he fog bank off shore and, nearby, the thin ice layer on the still water with its small dots of snow formed from what little humidity was in the air, freezing and gently falling in the extreme cold. - JW

Taken using a tripod-mounted Nikon D7100 fitted with a Nikkor 35mm f/1.8 DX, ISO100, Aperture Priority mode, f/7.1, 1/400 sec, EV-0.33 exposure bias. This is a single image processed in HDR software and thus it is tone-mapped rather than true HDR. HDR processing was done in free Open Source Luminance/Qtpfsgui using the Fattal tone-mapping operator to emphasize colour rather than detail. PP in free Open Source GIMP: used the tone-curve tool to adjust the tone-mapped image and get a better looking tonal range by shaping the curve slightly into a classical 'S' curve by slightly pulling down the curve about 15% in from the left edge and then pulling up the curve slightly about 15% in from the right edge, slightly reduced overall saturation and then further reduced the yellow channel saturation, duplicated the working layer, further brightened up the lower layer by pulling up slightly in the centre of the tone curve so that the detail in the deeper blue ice area (bottom of frame) showed its detail a bit better, deleted the area corresponding to the deep blue ice area with a large soft-edged eraser tool, created new working layer from the visible result, svery lightly boost contrast to get a bit of crispness to the image, sharpen, add fine black and white frame, add bar and text on left, scale to 1800 wide for posting.
