A lot of subjects I see as quite graphic and like to process as monochrome, to use that definition, as they impact better to me. This view changes from scene to scene, obviously, I like to have blocks of colour as well. Processed in the main in Lightroom, which has an abundance of adjustments.
This is a random selection from my library, all I think quite good, but I cannot be objective enough with them to differentiate sometimes, so much harder with my own stuff. Different genres of course.
