White Backgrounds-Here's another quick way to do it!
You've photographed your subject against a white background, but it still isn't quite as white as it needs to be, here's what you do.
In photoshop go to Image adjust>Curves>when the box pops up go to the top right hand side and pull the diagonal line to the left, voila! A nice white background.
