Corrected, thank you. At least the post is correct.
Processed in Capture One, first in colour and then also converted to black and white. Finally assigned a red and blue duotone using the Black and White/ Split Tones sliders for hue and saturation of both highlights and shadows. (In Lightroom I think you have to use the colour wheels for shadows and highlights).
No, I don't use presets, so I use different settings each time I do a duotone including different colours.
