Also, i finally learned how to trim out photos better, I magic wand everything like you usually do, then i select all the blank space, Inverse Selection(this is important) , then Refine edge.. the REFINE EDGE button is glorious.
 
Gotta make sure your selecting the pic and now all the area around it hence the inverse selection, when you refine edge i have been using smart radius, 1.4X Radius, Feather it a couple points, Decontaminate colors leave at 50% and it makes a new picture with a mask over it that clears up all the nasty hard to erase colors. SOOO many headaches before now gone with a few button presses.
