Thanks foe taking your time to explain what is happening in the pic. With all the simple technology tools, photographers can change a colorful picture into a black and white concept with one press of a button. Although the editing part might sound super easy, taking the perfect photo is a challenge. Anybody can pick up a camera and take a picture, but it takes a skillfull photographer like @velimir to take a magnificent photograph and use composition, exposure, and aperture as an advantage. You are doing a great job friend .
