Hello,
is there any possibility to select pixels with specific RGB values in Affinity Photo?
For example, in an picture from a fluorescence microscope, I would like to select all pixels with RED values >251.
I already tried with mask followed by a brush with different red values, but this did not work.
Unfortunateloy, with "Select/Color Range/Red" I cannot define the minimum red level of the selection. Seems to be a fixed value.
Any idea?
Regards,
Jens
