Mixing Channels - The Making of a B/W Picture

A brilliant Sunlight day with lots of bright blue sky and plenty of clouds, just right for a bit of infra red photography. Pity the wind was so bally cold.  A good job I'm not related to any brass monkeys. I was trying out a new IR filter on the 'full spectrum' 1200D. This one is infinitely adjustable from 530nm  to 720nm.

This photo was taken with it set to 530nm and the camera white balance set to the green grass.

Result as seen and taken by the camera:

The RAW file was adjusted for contrast and black level in Affinity Photo. Then the channel mixer was used to adjust each Red, Green & Blue level independantly on each R G & B channel:

Finally that was changed to B/W (greyscale) with a tad more tweaking:

  1. That's dramatic. And far too complicated for me to do!
