In my last post I shared an example of the false infrared colour technique and explained how it was achieved. I also confessed that in general I don’t like the effect, although in some cases it does work well. I thought it would be good to share another example that I think works reasonably well (although not as well as the previous post) although I will admit that I still prefer the traditional black and white conversion.
This example is a little more stylised than the previous image and was created by first converting the image to colour before applying a Fuji Provia Slide Film simulation in Exposure 6. This was then further edited with a boost to the Vibrancy slider and a negative Clarity to give the soft effect. My reasoning for these adjustments was to prepare the image for conversion to black and white but I found I quite liked the colour image.
When converting the images with the Channel Mixer it can seem a bit hit and miss. It appears to help if you have both sky and foliage in the image. With a Red/Blue channel swap such as shown here the sky will turn blue and the foliage will go red. Most other areas (in landscapes) tend not to be affected.
You can improve the results by picking a white balance point during RAW conversion which causes the foliage to take on a blue tint. Typically this will leave the sky with some red tint and when the channel swap is made with the channel mixer the red tint in the sky turns blue and the blue tint of the foliage turns red.
Also try to avoid images which have been shot in the shade (such as tree lined country lanes) as you won’t get such a good effect. You really need direct and strong sun to make this work well.
Hope this helps anyone who is also struggling with Infrared false colour.
