For anyone who is wondering this is how I make I backgrounds.
1.First you have to make a random background in photoshop (have fun!)
2.Then take the photo on a background that is a color that you have nowhere on your clone etc.
3.Then pull it up in photoshop along with your background.
4.Use the magic wand tool at 50 tolerance and select the background!( you may have to do it a few times and make sure
the backgound layer is titled "layer 0" by double clicking on it)
6.Make A new layer behind layer 0
7.Now Select your background and copy and paste it into your "layer 1"(size it appropriatly) and close your background file.
NOW, HERE COMES THE HARD PART!
8.Go to Image>Adjustments>Replace color(make sure you are on "layer 0")
9.You will have an orange (or whatever color background you used) glow to it here's how we fix it, select the orange glow on the picture (while you are still in replace color) and set the bottom color to a shade of grey.
10.Hit OK and save Viola you have a background!
Please Enjoy And if use this technique please give me credit!
