Clearstreet is a preset for Silver Efex that I made to give the photo a nice clear view as street photos. You may also use it with other photos, but you can try that for yourself. The beautiful, clear appearance is especially evident in photos that already have a lot of light, such as stray light or reflection light. In the example below is a nice light background and nice reflective lights in the window.
Below an additional example, the cover photo, in its entirety. Here you can see the effect of the light parts.
