Dan' de Bourgogne I agree with User ID here... building contrast with sharpening and/or a contrast (S) curve brings out bias relief... thereby aiding in the creation of an aura of depth.
btw the spiral you've chosen to illustrate here is actually a Fibonacci pattern... the same pattern of seeds within a sunflower which follows the Fibonacci sequence, or 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144...1 If you remember back to math class, each number in the sequence is the sum of the previous two numbers. ... This number is exactly the golden mean.
The seeds of sunflowers display a two-dimensional pattern involving the Fibonacci sequence. The seeds of a sunflower form two spirals, called parastichies, one set eminating from the center in a clockwise direction, the other in a counter-clockwise direction.
Since many are now becoming aware of the Fibonacci sequence which is the bases of the DNA double helix molecule also based on the golden section, and are numbers in the Fibonacci series and their ratio.
The only two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine. Yes Covid is simply an RNA molecule.
For those with a background in mathematics and bio medicines I would suggest a much deeper dive into the origins of life itself... again the Golden Ratio, ϕ = 1.61803

It is truly a surreal quality that seemingly holds the mysteries of our virtual existence and the creation of life itself.
Not a subject of many theological institutions but a truly awesome clue as to our own origins and it is being pursued in earnest by the most brilliant minds in the scientific community.
Thank you for sharing your Fibonacci sequence Dan' de Bourgogne
