Infrared emulation

Macros for Affinity Photo

Back in James Ritson created a video tutorial showing how to emulate infrared photography using Affinity Photo. It is a simple procedure, but involves lots of clicking. I have recorded two macros to speed up the whole processes: one for colour emulation and another if you want to go with a monochrome option.

The process is non-destructive – each macro duplicates an original background layer and creates additional adjustment layers that can be easily tweaked afterwards.

Colour infrared emulation macro copies the background layer and inverts it with blend mode set to Colour, then creates Channel Mixer Adjustment layer (swaps red and blue channels), adds Diffuse Glow adjustment layer. On the end the macro adds HSL adjustment layer. You can adjust HSL (Hue, Saturation, Lightness) adjustment layer to your liking – usually reduce saturation of red and increase saturation of yellow. You can also change Diffuse Glow adjustment layer.

Monochrome infrared emulation macro copies the background layer and inverts it with blend mode set to Colour, later it creates Channel Mixer Adjustment layer (swaps red and blue channels), and on the end it adds Black & White adjustment layer where you can manage lightness value of the named colour areas of the image.

Simply add macros to Affinity Library panel and it is all done for you.

  1. Download infrared macros (infrared.afmacros 3kB)
  2. Open Library panel: ViewStudioLibrary
  3. Import macros (top right small hamburger menu icon and chose Import macros… in macros panel)
  4. With a photo for emulation in layers panel selected click one of two available options: Infrared or Infrared monochrome
