How to remove something from a photo using Clone Stamp Tool in Photoshop (Hard Edit)

This video is for those who want to remove something from their photo like a person , an object or even cars in Photoshop . The clone stamp tool is perfect when you need to remove something that a spot healing brush tool or even lasso tool won't do.
I used Shortcuts (only for Windows OS) :
Alt : To first select a pattern.
[ , ] : Brackets to decrease or increase the size of brush.
