Custom made background image

I started with  this  found sports court image and ran it through photoshop...

Sourced from:

http://www.gamecourts.com/ClientFiles/GameCourts/Assets/UserFiles/file/tile_and_lines.jpg

Converted the image to greyscale then  adjusted the Brightness and Contrast.
I then used the burn tool too create this darker shadow perspective off into the distance effect.

Final BG:

I left the black bar in the middle as that wont be seen due to the large container over it which will be black to give the layout visual symmetry which looks aesthetically better
