I have just recently taken to infrared photography. Great fun!
One of the most crucial editing steps in IR editing is to swap the red and blue channels. This transforms the pictures from having orange skies and light blue foliage into pictures with blue skies.
I currently process my raw files in PL3 and then do the channel swap and other editing in Affinity Photo. I do this by using their “Channel mixer” tool, set the reds in the red channel to 0, the blues in the red channel to 100 and vice versa for the blue channel.
Is there any way to do this in PL3? It would save me a ton of hassle, especially since I could batch edit my raw files with PL3.
Thanks! That did work. Not quite where I want it to be yet but it is definitely possible.
For anyone else wanting to try this: just sliding the red or the blue does nothing. You have to extend the range to a third of the wheel by dragging the two inner points on the circle outwards. Best results (so far) by then sliding the outer point to the opposite end of the wheel.
As an example, I made this night shot b/w using the white pill with max desaturation and then changed the red balloons to blue using the steps mentioned above. Lastly, I desaturated some leftover blues using the local adjustment paintbrush.
