Redirecting Non-logged in Users

Hello ,

I need a system where all the non-logged in visitors to my site are redirected to a landing page.

CASE 1 : I have tried using this code below

if( !is_user_logged_in() ) {
	wp_redirect('http://facepassion.com/welcome') ;
	exit;
}

It works but i don’t like the way it is preventing them from reading posts and pages.

Is there a way i can redirect them only to the landing page but not restricting them from reading pages and posts.

Anyone here to help ?

Thanks in Advance.
