Here is a link i recommend that you read, Photoshop users. I just discovered this one, of all the years i’ve been using Adobe Photoshop, i think it’s now time that i use this one.

It’s called the Background Eraser Tool 😀 pretty handy for rush designs and simple background changes.

Hope it helps you guys!
