There’s something about this photo I’ve always liked. It was taken in 2013 and something inside back then inspired me to play with color settings on one of my image processors. I liked what I had come up then with so I re-did the processing here some 12 years later.

The original NEF image was taken under natural daylight, has pixel size of 7370/4916, was translated to TIF with ProPhoto color, then scaled with no further processing to 800/534 JPG with zero-compression and print resolution of 300px/in.
But I go further … and y’all get to experience the joy of pretending you’re in an art gallery, examining works of “fine art” exploring variations in hue, saturation, and a bonus example image of edge detection.
Or not …
The same conversions and scaling were used as in the original print with the addition of adjusting hue and saturation. No mixture of hues was utilized; color filters were RED, YEL, GRN, CYN, BLU, and MAG. Saturation levels for each color were 0% or 100%.
Only RED:

The RED only appears more orange than red and appears over-emphasized when other colors are removed.
Only YEL:

On the other hand, while YEL-only is mostly emphasized on the edges, the color is not as over-whelming as RED-only.
All colors except RED and YEL:

Other than a small hint of green grass through a gap in the machinery, it appears to be a black&white image.
All set to 0% saturation:

With all colors set to 0% saturation, the image appears fully B&W
No adjustments to saturation or hue; conversion of ORIG to Gray-scale (B&W)

At this scale, it’s hard to differentiate between the last three, but there are subtle differences between the 0-saturation image and the gray-scale image. Differences in the conversion algorithms but subtle enough to not be noticeable at first glance of a scaled image.
Just for grins, I applied a basic EdgeDetect filter:

There you have it.
The original is OK as is, but I believe my preference is B&W.
